Bomba all'uranio Little Boy arricchito del peso di 3. The Mk-I was a gun-type nuclear gravity bomb using highly enriched uranium. It detonated meters over central Hiroshima at 8: The airburst height was selected to maximize the extent of prompt effects and to minimize residual radiation fallout.

Individuals at ground zero received combined gamma and neutron doses of perhaps 80, rad, although flash and blast would have been immediately fatal. The thermal flash produced fires which merged into a firestorm, razing much of the city.

Flash, blast, and prompt radiation killed most people within 1. Small numbers of people were injured by residual radiations neutron-induced radioactivity and residual material from the weapon.

On the day of the bombing, an estimated , people were in Hiroshima, including , Japanese residents, 20, Korean residents, 12, conscripted Japanese workers, 3, conscripted Korean workers, 48, Japanese soldiers, and a small number of prisoners of war. Casualty figures are uncertain, despite many surveys some figures presented here are extrapolated from partial surveys.

Among civilians, possibly 44, to 59, were killed the day of the bombing, with another 17, missing. Subsequent deaths include about 25, through the end of August , 9, in September , 2, in October-December , and 2, in Many of these subsequent deaths involved radiation injuries.

Deaths among survivors after include greater fractions from natural causes. Less information is available regarding military fatalites, but at least 9, soldiers died through the end of The estimated , fatalities to include about , Japanese civilians, 12, Japanese soldiers, and 6, Koreans.

After , deaths attributed to radiation include about 60 leukaemia deaths, other cancer deaths, and non-cancer deaths. New cases of leukaemia peaked in Those injured in the bombing numbered through August 30, severely injured and 48, slightly injured. These figures do not include a possible 7, injuries among military personnel. Of 2, medical personnel in Hiroshima at the time of the bombing, 1, were killed or injured.

Emergency response was supported by the arrival of about 3, medical personnel from surrounding areas and other parts of Japan, along with another 2, relief workers. An additional 40, to 60, are registered as having entered Hiroshima shortly after the bombing. Survivor registries include 2, individuals exposed in utero.

Studies suggest that excess miscarriages and fetal deaths numbered in the dozens, and excess infant deaths for those exposed in utero also in the dozens. About 45 cases of microcephaly are known among those exposed in utero, including at least 15 with mental retardation. Portions of Hiroshima with little or no damage were continuously inhabited, and the city was rebuilt.

The primary target city, Kokura, had been covered by clouds, as was Nagasaki the secondary target when the bomber arrived. The bomb was dropped through a gap in the cloud cover over a point somewhat displaced from the city center. It detonated meters over Nagasaki at Individuals at ground zero received combined gamma and neutron doses of perhaps , rad, although flash and blast would have been immediately fatal.

The thermal flash produced fires which swept through much of the city. On the day of the bombing, an estimated , were in Nagasaki, including , Japanese residents, 10, Korean residents, 2, conscripted Korean workers, 9, Japanese soldiers, conscripted Chinese workers, and prisoners of war. Estimated fatalities are 70, various published estimates range from 22, to 74, , including 2, Koreans and at least POWs.

After , deaths attributed to radiation include about 35 leukaemia deaths, other cancer deaths, and 85 non-cancer deaths. Those injured in the bombing numbered 74, through December Thousands of injured survivors were transported by train and other means to neighboring cities.

From 10, to 30, are registered as having entered Nagasaki shortly after the bombing. Survivor registries include 1, individuals exposed in utero. Japan surrendered three days after the bombing, ending World War II. Portions of Nagasaki with little or no damage were continously inhabited, and the city was rebuilt. Nagasaki reattained its pre-attack population by and had a population of , in Due giorni dopo la bomba atomica di Nagasaki, gli scienziati giapponesi di stanza a Konan il maggiore complesso industriale sotto il controllo nipponico ed ignari della decisione presa dall'imperatore di arrendersi evitando ulteriore morte e devastazione, eseguono un test nucleare: Per diversi giorni relitti di imbarcazioni e altre vecchie navi furono portate sull'isola che era talmente piccola da non risultare su molte mappe.

I pochi abitanti furono evacuati. Venti miglia dall'isola gli osservatori aspettavano e pregavano che gli assidui sforzi avrebbero prodotto il risultato che tanto speravano: Il risultato fu sorprendente: Un fungo atomico che probabilmente era molto simile a quello di Hiroshima e Nagasaki.

Ma tutto fu inutile per la presa di posizione dell'imperatore di cessare i combattimenti. Peranto, una volta a conoscenza dell'imminente resa, gli scienziati giapponesi si diedero da fare per distruggere tutti i loro documenti nonche' tutto l'equipaggiamento e strumentazioni possibili incluse altre bombe atomiche quasi completate perche' i russi ormai avanzavano verso il complesso di Konan dalle montagne nel nord della Corea.

Daghlian crea accidentalmente una massa subcritica, lasciando cadere un mattone di carburo di tungsteno su un nucleo di plutonio. Lo scienziato rimuove subito il mattone, ma resta fatalmente irradiato. Morirà il 15 settembre. An experimenter was hand-stacking tungsten carbide bricks around a plutonium metal assembly. The plutonium assembly comprised two hemispheres with a total mass of 6. While moving a final brick, the experimenter noticed from neutron counters that the final brick would make the assembly supercritical.

At this point he accidentally dropped the brick onto the pile, providing sufficent neutron reflection to result in a supercritical power excursion. The experimenter quickly removed the final brick and disassembled the assembly. He sustained a dose of rem and died 28 days later. A nearby Army guard received a dose of 50 rem. A French minesweeper explodes near Marseilles, killing five. Navy shore-liberty boat capsizes in San Francisco Bay, California. Fire damages four Royal Navy minesweepers docked at Dover, U.

Il fisico canadese Louis Slotin assembla manualmente una massa critica di plutonio durante una dimostrazione. Il suo apparecchio era costituito da due semi-sfere di plutonio ricoperte da berilio, che poteva essere rimosso lentamente per misurare la criticità.

Normalmente le sfere avrebbero dovute essere manipolate da una macchina, ma Slotin lo fece manualmente inserendo le sue dita in fori, come in una palla di bowling. Un certo numero di cuscinetti avrebbe dovuto impedire alle due semi-sfere di cadere, ma li aveva rimossi. Aveva usato un cacciavite per controllare lo scarto fra le due semi-sfere.

Ad un certo punto il cacciavite è scivolato e l'insieme è diventato critico. Nessuno dei sette osservatori ha ricevuto una dose mortale, ma Slotin muore il 30 maggio di un avvelenamento massivo, stimato in 1.

An experimenter was demonstrating techniques to a group using a plutonium assembly. The assembly comprised two hemispheres of plutonium metal, total mass 6. The experimenter had the two hemispheres together, separated by a screwdriver supporting the top hemisphere, when the assembly became supercritical. He separated the assembly within 0. The experimenter received a dose of rem, from which he died 9 days later. The other individuals in the room received doses of , , , , 65, 47, and 37 rem.

The individual receiving the second highest dose, a woman, was the only other individual to develop radiation sickness.

Un bombardiere B sgancia d'urgenza una bomba in mare, senza esplosione. The warhead contained uranium instead of plutonium. After six hours of flight, the bomber experienced mechanical problems and was forced to shut down three of its engines at an altitude of 12, feet 3, m. Fearing that severe weather and icing would jeopardize a safe emergency landing, the weapon was jettisoned over the Pacific Ocean from a height of 8, ft 2, m.

The weapon's high explosives detonated upon impact. All of the sixteen crew members and one passenger were able to parachute from the plane and twelve were subsequently rescued from Princess Royal Island. The Pentagon's summary report does not mention if the weapon was later recovered. A Royal Navy midget submarine explodes in Portsmouth harbor, U. Un bombardiere B si schianta contro una montagna, vicino alla baase aerea di Kirtland AFB, e brucia.

Three minutes after departure from Kirtland Air Force Base in Albuquerque a B bomber carrying a nuclear weapon, four spare detonators, and a crew of thirteen crashed into a mountain near Manzano Base. The crash resulted in a fire which the New York Times reported as being visible from 15 miles 24 km The bomb's casing was completely demolished and its high explosives ignited upon contact with the plane's burning fuel.

However, according to the Department of Defense, the four spare detonators and all nuclear components were recovered. A nuclear detonation was not possible because, while on board, the weapon's core was not in the weapon for safety reasons.

All thirteen crew members died. Un bombardiere B si schianta. La carica esplosiva della bomba salta, lo stadio nucleare resta inattivo. Mechanical difficulties caused the bomber to nosedive from a height of 7, feet and crash. The weapon's high explosives detonated upon impact, causing an explosion felt well over 25 miles away and creating a crater 25 feet deep and feet square. Four officers and twelve airmen were killed in the accident.

Paul CA suffers a powder blast in a gun turret while operating off Korea, killing The uranium oxide was in small particles most 10 microns in diameter, some 40 microns in diameter embedded in polystyrene plastic; a total of 6. These fuel strips were combined with zirconium strips in a water-containing tank.

Contrary to operating procedures, a control rod was being replaced while the tank was filled to the normal level with water. A criticality excursion occurred, heating the fuel sufficiently to cause bubble formation near the larger uranium oxide particles. This bubble formation forced most of the water out of the core, terminating the excursion within 0.

Most of the 3 megajoule energy release occurred in a period of about 0. Doses to four individuals were , , 60, and 9 rad. The Zephyr suffers flooding in one of its magazines. The submarine's periscope and radar mast are damaged.

Procedural errors in an unrecognized accumulation of g of plutonium in one vessel, which became critical and brought the vessel contents to boiling. The operators transferred contents of another vessel to the first, ending the reaction. The accident was unrecognized for 2 days when one operator developed symptoms of radiation sickness. This operator had received a 1, rad dose, resulting in severe radiation sickness. He also sustained severe radiation burns on his legs, requiring amputation of both legs, but survived another 35 years.

A second operator received a rad dose; this worker and a third operator both developed radiation sickness. The captain of the Naboland is held by Turkish authorities in connection with the incident, and on 11 April Sweden protests his arrest. The Netherlands charges that U. State Department later reports anti-aircraft artillery shells were accidentally fired within two miles of the plane. The USS Leyte CV is badly damaged by an explosion and subsequent fire caused by the accidental ignition of hydraulic fluid on a catapult while moored at Charlestown Naval Yard, Boston, killing The fire takes five hours toextinguish.

Navy landing craft off Inchon, South Korea, drowning 28 Marines. The first shot in the series was Bravo, a test of the "Shrimp" TX device, with a predicted yield of 6 megatons. The device was placed at the end of a causeway extending onto the reef meters from the southwest tip of Namu island in Bikini Atoll.

It was detonated at 6: Additionally, shortly after the detonation the wind shifted from northward to eastward. A Japanese fishing boat, the Fukuryu Maru Lucky Dragon was just outside the km radius restricted zone and received heavy fallout beginning about 1. The 23 crewmembers did not recognize the falling material as hazardous and made little effort to minimize their exposure to it; some crew members tasted the fallout. Some crew members began developing radiation sickness within three days, and the entire crew developed acute radiation sickness before the boat returned to Japan on 14 March.

On return to Japan, the boat's owner recognized the crew was ill and called a hospital, which referred the men for treatment the following day. One member of the Fukuryu Maru crew died of a liver disorder, a complication from radiation sickness, on 23 September Significant fallout also fell on inhabited islands west of Bikini under U.

The highest doses were to the 64 inhabitants of Rongelap Atoll about km from ground zero , some of whom received rads before their evacuation 44 hours after the detonation. Some reports indicate that Rongelap inhabitants unaware of the nature of the fallout did little to minimize exposure, including inadvertent ingestion of fallout, contributing to acute radiation injury.

In addition, 37 U. Some evacuated inhabitants of downwind atolls later developed thyroid hypofunction; thyroid exposure for some who were children at time of exposure is estimated at , rad and at rad for some adults.

The Japanese fishing boat Kine-Maru sustains damage as a result of shots fired by vessels of the Netherlands, Australia, and New Zealand during target practice in "Area George.

State Department rejects the claim, saying that "Area George" is located on the high seas and that its use does not require permissionf rom the Japanese government. Several weeks before its first sea trials, a small steam pipe in the reactor compartment of the USS Nautilus SSN bursts, filling the area with steam during a test of the steam system while the ship is at the Electric Boat Shipyard in Groton, Connecticut. The test is part of a quality control effort to check the adequacy of the shipyard's inspection system.

The incident initially appears to be minor. There are slight personnel injuries and no radiation hazards. However, subsequent investigation shows the situation is more serious. Specifications called for seamless pipe, but ordinary stanchion pipe had been used. All suspect pipe is ripped out and the mistake leads tomore stringent quality control measures. The Battleaxe suffers a five-foot-hole in its bow, but is able to return to Plymouth Sound, U.

A bomb disposal expert stated it was a miracle exposed detonators on one bomb did not fire, which presumably would have released nuclear material into the environment.

The experimental sodium-cooled nuclear reactor of the USS Seawolf SSN suffers a failure in the steam plant during a full power test run while the new ship is at Groton, Connecticut.

A leak of sodium-potassium alloy being used as the third fluidin the steam generator aggravates stress corrosion in the system, causing two cracks in steam piping and a leak in a superheater. Makeshift repairs permit the Seawolf to complete its initial sea trials on reduced power in February Due to the difficulties of running a sodium-cooled reactor, the Navy decides to replace the Seawolf's sodium-cooled reactor with a water-cooled reactor, and use only water-cooled designs in the future.

The Nautilus mistakes the ship for an aircraft carrier on its sonar. Fra il e il , kg. Il materiale permette di fabbricare più di una bomba atomica. Il presidente della società aveva delle relazioni con Israele, ma il mistero non è mai stato risolto.

For several reasons, an unexpectedly large amount of uranium precipitate accumulated in a filter receiving vessel. The operator at the glovebox observed the filter vessel to bulge prior to ejection of gas and some solution and precipitate from the vessel within the glovebox. The operator gathered some precipitate by gloved hand and returned it to the vessel; within seconds she began to feel ill.

It was not recognized that a criticality excursion had occurred until the radiation control officer made measurements minutes later. The female operator received a whole body dose of 3, rad or 4, rad, developed nausea, vomiting, headache, and fatigue within minutes, and died 12 days later.

The other five operators in the room at the time received doses over rad, and five other individuals sustained doses up to rad; the five operators developed radiation sickness one report suggests all ten did. All ten 3 male, 7 female recovered. Roosevelt CVA reportedly hits a submerged object off Florida.

The object is not thought to be a submarine. The Navy later denies that the carrier had hit an object, claiming instead that a propeller had broken. The wharf is heavily damaged, while damage to the carrier is light. Navy experimental X-1 submarine is damaged by a blast at the Portsmouth Naval Shipyard. There are no injuries. Una bomba nucleare senza la sua capsula fissile cade dal vano bombe di un B ad un'altitudine di circa metri ed esplode all'impatto.

Il bombardiere stava trasportando entrambe le bombe e la loro capsula fissile, che era stata rimossa per sicurezza, dalla base di Biggs dell'Air Force in Texas alla base di Kirtland in New Messico.

Sebbene i paracaduti attaccati alla bomba si fossero aperti durante la sua caduta, essi non funzionarono correttamente. La bomba nucleare fu completamente distrutta nella detonazione che accadde a circa 7 Km. I frammenti della bomba e i detriti furono dispersi su di un area di oltre 1. Eleven depth charges explode prematurely off the stern of the USS Whitehurst DE 18 miles off Pearl Harbor, endangering the lives of a Hollywood movie cast on board to shoot a movie scene.

Un aereo da trasporto C con problemi meccanici abbandona due armi nucleari, senza la loro capsula di materiale fissile, al largo della costa orientale degli Stati Uniti. Il C, sulla rotta dalla base aerea di Dover a Delaware, perde potenza nei motori numero uno e due.

Anche se nessuna bomba detona, si presume che entrambe le bombe si siano danneggiate nell'impatto con la superficie dell'oceano e che siano affondate quasi istantaneamente. Nessuna delle due bombe, né detriti sono mai stati trovati. Il C atterra per sicurezza su un campo d'aviazione vicino ad Atlantic City, nel New Jersey, con la bomba rimanente e la testata nucleare a bordo. The Peruvian diesel submarine Iquique is freed from a sand bar where it had run aground during trials in the Long Island Sound, New York.

In the first few days of September, the USS Nautilus SSN suffers damage to two periscopes while rising under ice conditions during an exploratory trip under the Arctic icepack. The Nautilus returns from under the icepack to the open sea to perform repairs on the surface.

It takes 12 hours in rough seas, freezing temperatures, and gale winds to fix one periscope. The other is damaged beyond repair. A fire began in a materials handling glove box and spread through the ventilation system into the stack filters at the Rocky Flats weapons mill 27 kilometres 17 mi from Denver, Colorado.

Plutonium and other contaminants were released, but the exact amount of which contaminants is unknown; estimates range from 25 mg to kg.

No damage is reported. A small hole is punched in the Purdy's hull above the waterline. In una fabbrica di armi nucleari negli Urali e stoccaggio di scorie radioattive, una cisterna contenente scorie radioattive prende fuoco ed esplode, contaminando migliaia di chilometri quadrati di terreno.

Una nube, contenente più di 2 milioni di curie di prodotti radioattivi, si solleva per più di un chilometro in altezza la metà di quanto rilasciato a Chernobyl. Il rilascio esterno di radioattività avviene a seguito di un malfunzionamento del sistema di refrigerazione di una vasca di immagazzinamento di prodotti di fissione ad alta attività. Vengono esposte alle radiazioni circa Si stimano per le conseguenze dell'incidente oltre morti.

Nella zona vengono installati cartelli stradali con le scritte: Nel , il quotidiano francese Libération rivela che i materiali radioattivi stanno riemergendo in superficie ingiallendo le acque sotterranee. I principali materiali rilasciati sono gli isotopi radioattivi di xenon, iodio, cesio e polonio.

La nube attraversa l'Europa intera. Sono stati ufficializzati soltanto morti per cause ricondotte all'incidente malattie, leucemie, tumori , ma il dato potrebbe essere sottostimato.

La radioattività su Londra giunse fino a 20 volte oltre il valore naturale, e Londra dista da Windscale km. Il consumo di latte venne vietato in un raggio di 50 km una zona di kmq.

Nel un documentario della televisione britannica rivela che nel villaggio di Seascale, non lontano da Sellafield, il tasso dei bambini colpiti da cancro è dieci volte più elevato che la media nazionale. Secondo il giornale Le Monde del 2 gennaio , il vecchio primo ministro conservatore britannico, Harold Macmillan, aveva ordinato di insabbiare un rapporto dettagliato sulle cause di un grave incendio avvenuto all'interno di una fabbrica per il ritrattamento delle scorie nucleari di Windscale.

Un bombardiere B si schianta con una bomba di cui la carica nucleare era disinnescata. L'aereo brucia, esplode la carica classica. A B bomber carrying a nuclear weapon and its separated fissile core crashed shortly after takeoff.

The aircraft crashed in an inhabited area approximately 3, feet from the end of the runway, enveloping the nuclear weapon and its fissile core in flames which burned and smoldered for approximately four hours.

Although two small explosions occurred during the burning, the weapon core and its carrying case were recovered intact and only slightly damaged by the heat. Approximately one-half of the weapon remained and all its major components were recovered but damaged. The Washington Post reports that the reactor compartment of the USS Nautilus SSN flooded several days ago after a small leak developed while the submarine was in port in Connecticut.

The leak was due to the malfunctioning of a valve, and according to the Navy caused no radioactive contamination or damage to the power plant.

Catastrofe nucleare a causa dell'esplosione di un deposito di scorie radioattive. Decine di migliaia di contaminati. Criticità di incidente con soluzione di uranio Following the criticality accident at the same facility in , an apparatus had been constructed to test criticality phenomena in fissile solutions. A liter tank on a platform was used for measurements involving solutions; after each experiment, the tank was drained into individual 6-liter containers of favorable geometry.

After filling several 6-liter containers, operators decided to circumvent the standard procedure to save time. Three operators unbolted the tank and lifted it to pour directly into containers. The presence of the operators provided sufficient neutron reflection to cause a criticality excursion, producing a flash of light and ejecting solution as high as the ceiling, 5 meters above the tank.

The operators dropped the tank and, along with a fourth operator in the room, left the area for decontamination and transport to the hospital within 2 hours of the accident, having already exhibited symptoms of acute radiation syndrome. The three operators who lifted the tank all men incurred fatal doses of radiation, with respective doses of 7,, rad died on day 6 , 7,, rad died on day 7 , and 3,, rad died on day The fourth operator, a woman, sustained a dose of , rad but recovered from radiation sickness.

She suffered chronic health problems afterwards, developing cataracts in both eyes and becoming blind years later, eventually dying of lung cancer in Un treno merci diretto a est deraglia nella ferrovia Nickel Plate. Cinque automobili che trasportano "materiale classificato AEC" sono coinvolte nell'incidente. Secondo il rapporto della Commissione indagante non c'è stato alcun danno al materiale e alcun ferito tra il personale AEC che scortava il carico.

Un bombardiere B con una bomba nucleare in configurazione d'attacco sta compiendo un decollo simulato durante un'esercitazione quando la ruota posteriore sinistra viene a mancare, provocando l'urto della coda contro la pista e la rottura del serbatoio del carburante.

L'aereo prende fuoco e brucia per sette ore. Sebbene l'alto esplosivo non detoni, si ha contaminazione nell'area immediatamente circostante allo schianto. In seguito all'incidente, le esercitazioni di allertamento vennero temporaneamente sospese.

Un servizio del New York Times dell'8 giugno , menziona un incidente di bomba nucleare che era accaduto "in un campo degli Stati Uniti vicino Tripoli, in Libia", senza fornire ulteriori dettagli. Febbraio - Luogo ed aereo sconosciuti. An unidentified aircraft crashed "on base" while carrying a MK-7 training weapon in February, Aircraft wreckage and weapons parts were scattered over an area approximately feet wide by 0.

The largest piece of weapon recovered was located with part of the plane's tail section. Un bombardiere B che sta subendo un guasto al motore durante il decollo espelle due cisterne piene di 6.

Il fuoco che ne deriva brucia per 16 ore e causa la deflagrazione delle alte cariche esplosive di almeno una bomba atomica. L'esplosione rilascia materiale radioattivo, includendo uranio polverizzato e ossido di plutonio, dei quali almeno grammi vengono trovati intorno alla base. Inoltre un hangar adiacente è gravemente danneggiato e altri aerei vicini vengono spruzzati con pompe d'acqua per prevenirne l'incendio a causa dell'intenso calore alimentato dal combustibile per jet e dal magnesio del B Il fuoco uccide due persone, ne ferisce altre otto, e distrugge il bombardiere.

L'Air Force non ha mai ammesso ufficialmente che armi nucleari fossero coinvolte in questo incidente. L'Air Force e il ministro della difesa inglese furono d'accordo nel di negare l'esistenza delle bombe nucleari in qualsiasi incidente che coinvolgeva le armi nucleari statunitensi collocate in Inghilterra. The Swedish diesel submarine Illern sinks in a shipyard, Malmo, Sweden. Un'arma nucleare senza la capsula nucleare fissile viene perduta in seguito ad una collisione a mezz'aria.

Un bombardiere B trasportante un'arma nucleare senza il suo nucleo fissile, si scontra con un aereo F vicino a Savannah, in Georgia. Dopo tre tentativi senza successo per far scendere l'aereo alla base Hunter in Georgia, l'arma viene gettata via per evitare il rischio di un'alta detonazione esplosiva nella base stessa. L'arma viene rilasciata in mare a diverse miglia dalla foce del Savannah River a Wassaw Sound al largo di Tybee Beach, ma il preciso punto dell'impatto rimane sconosciuto.

Gli alti esplosivi dell'arma non esplodono nell'impatto. Una ricerca successiva, su un'area di 5 km. La ricerca viene sospesa il 16 aprile , e la bomba viene considerata irrimediabilmente persa. La migliore stima della posizione della bomba, annota un resoconto del Dipartimento della Difesa, " è stata determinato essere 31 gradi 54' e 15'' a nord, 80 gradi 54' e 45'' ovest". Il B era in una missione di combattimento simulata dalla base dell'Air Force di Homestead in Florida.

Una bomba atomica è sganciata per errore e cade in un giardino. Esplode la carica classica. Viene distrutta la casa e gli abitanti vengono gravemente feriti. Il cratere provocato è di 20,5 m. The bomb's high explosive material exploded on impact, causing property damage and several injuries. The aircraft, which was heading to an undisclosed overseas base, returned to Hunter Air Force Base in Georgia without further incident.

Numerous accounts of the accident describe the bomb falling in the garden of Mr. The high explosive detonation virtually destroyed his house, creating a crater feet in diameter and feet deep. It caused minor injuries to Mr. Gregg and five members of his family, and damaged five other houses as well as a church. Following the accident, Air Force crews were ordered to "lock in" their nuclear bombs, which reduced the possibility of accidental drops but increased the danger during a plane crash.

The source of the leak cannot be pin pointed, however, and the ship proceeds to Seattle,Washington. During the trip to Seattle, the captain decides touse the same type of additive that is sold for leaky car radiators to try to repair the leak in the condenser.

Upon arriving in Seattle in late May or early June, quarts are purchased and half are poured into the cooling system. The reactor plantis started and the leak stopped. The USS Nautilus SSN suffers a fire in the insulation around one of its turbines as the ship is running submerged in the Pacific shortly after leaving Panama on its way to its Arctic mission.

The insulation had become oil-soaked during the submarine's three years of operation and had caught fire. The fire is put out with minor injuries, but the submarine must surface to ventilate. Incendio al reattore e fuga radiottiva. Due to inadequate cooling a damaged uranium fuel rod caught fire and was torn in two as it was being removed from the core at the NRU reactor.

The fire was extinguished, but not before radioactive combustion products contaminated the interior of the reactor building and to a lesser degree, an area surrounding the laboratory site.

Over people were employed in the clean-up. There are no casualties. The submarine had lost power and drifted into the Silverstein's path. There is little damage. Un incidente a Oak Ridge: The leak was not properly logged. The following day other tanks were being drained into a gallon drum; uranium solution from the leaking tank also entered the drum. The operator nearest the drum noticed yellow-brown fumes rising from the drum's contents; he retreated before seeing a blue flash as the criticality excursion occurred.

Excursion power output rose for at least 3 minutes, then ended after 20 minutes. Eight people received significant doses: Navy barge used for research in under water explosions suffers an explosion and flash fire while in port at Norfolk, Virginia.

The Royal Navy destroyer HMS Hogue collides with the British trawler Northern Foam while trying to prevent the arrest of the trawler by an Icelandic patrol boat for illegally fishing in Icelandic waters.

A subcritical foil counting experiment was being performed when an experimenter noticed the smell of ozone and realized a criticality excursion was occurring. The power buildup had gone undetected as the water level was raised due to saturation of both detecting chambers. The total energy release was about 80 million joules about 2 kg of TNT equivalent. The six individuals in the room received doses of , , , , , and rem. All developed severe radiation sickness and one died.

The five survivors all received experimental bone marrow transplants, which were rejected in all patients, although before rejection the transplants probably contributed to survival. During a subcritical counting experiment a power buildup went undetected at at the Boris Kidrich Institute's zero-power natural uranium heavy water moderated research reactor. Saturation of radiation detection chambers gave the researchers false readings and the level of moderator in the reactor tank was raised triggering a criticality excursion which a researcher detected from the smell of ozone.

Six scientists received radiation doses between to rems. An experimental bone marrow transplant treatment was performed on all of them in France and five survived, despite the ultimate rejection of the marrow in all cases. A single women among them later had a child without apparent complications.

This was one of the first nuclear incidents investigated by then newly-formed IAEA. Un B si schianta dopo il decollo. Il materiale nucleare non viene danneggiato. A B bomber carrying a nuclear weapon caught fire during takeoff and crashed from an altitude of 1, feet, killing one crew member. The resulting detonation of high explosives created a crater 35 feet in diameter and six feet deep.

Nuclear materials from the weapon were recovered near the crash site. The Growler, designed for launching the Regulus II sea-to-landmissile, was several hundred feet below the surface when the leak developed in an improperly adjusted sonar compartment fittingfor an electrical cable. A careless act by two crewmen trying to obtain gunpowder from the magazine to fuel a minature ram jetengine they had built caused the explosion.

The Navy said the two men were known rocket enthusiasts and were not authorized to be in the magazine area at the time of the explosion. The "relatively minor" damage takes about amonth to repair due to the location of the accident. Un aereo C che trasporta una bomba nucleare senza la sua capsula fissile si schianta durante il decollo, distruggendo completamente l'aereo e la bomba nucleare.

Si ha una quantità limitata di contaminazione immediatamente sotto alla bomba distrutta, tale da non impedire, fortunatamente, operazioni di salvataggio o di spegnimento. When stirring of the tank began, a criticality excursion occurred which ended as the contents became more fully mixed. An operator who was viewing the tank received a dose to his upper body of 12, rem and died 36 hours later. Two others were exposed to doses of and 53 rem but suffered no ill effects.

In the late s, a Soviet Northern Fleet diesel-powered submarine, possibly a Whiskey class submarine, reportedly sinks. The vessel was specially converted to be a test platform for a Soviet cruise missile, which was under development. The submarine went to sea carrying empty missile containers and sankon its return voyage.

FINE - Alla fine del , gli esperimenti nucleari hanno prodotto sul pianeta circa 65 chili di stronzio 90, con una radioattività totale di 8,5 milioni di curie; la radioattività del cesio , alla stessa epoca, ammonta a 15 milioni di curie.

Il fall out degli esperimenti americani e britannici, di grande potenza, e tutti. Tra il ed il , gli USA hanno eseguito 90 test nel poligono nucleare del deserto del Nevada. Queste esplosioni hanno rilasciato una quantità di iodio superiore di dieci volte a quella che si è sprigionata dalla centrale di Chernobyl. Gli stessi test hanno esposto mediamente ogni cittadino statunitense ad una radiazione pari a 2 rad quelli provenienti dalla radioattività naturale ammontano a soli 0,24 rad annuali.

Alcuni medici hanno calcolato che circa The plane was carrying a payload of one nuclear weapon and three external fuel tanks. The fire was doused in about seven minutes and there were no contamination or cleanup problems. The accident occurs during routine operations off the U. The Navy says nobody was hurt. According to the Navy, the fire spread from the galley into the ventilation lines of the crew's mess.

But quick action by crew members "resulted in the saving of the ship's equipment and possible loss of life. Mackenzie DD recently collided during maneuvers in the western Pacific.

Secondo Makhijani, presidente dell' Institute for Energy and Environmental Research, "Le misurazioni di Iodio 31 sono state da 80 a volte più importanti di quelle rilevate a Three Mile Island". The Soviet ship reportedly stands by with its engines stopped while the Christel's crew works to plug a hole, then steams off when the Christel is out of immediate danger.

Navy discloses that a ruptured water pipe aboard the USS Nautilus SSN partly flooded a compartment while the ship was submerged off Newfoundland four months ago. The USS Wasp CVS is heavily damaged by an explosion and subsequent fires when a helicopter engine explodes while beingtested in hangar bay Number 1 as the ship is operating miles east of Norfolk, Virginia. The fires and reflashes take over two hours to control.

The ship was carrying nuclear weapons. In the first 30 minutes as the fires burned out of control and the forward magazines were flooded, preliminary preparations also were made to flood the nuclear weapon magazine. It was not flooded, however, and 30 minutes later the nuclear weapon magazine reported no significant rise in temperature. But water from the fire-fighting efforts eventually leaked into the nuclear weapon magazine around electrical cables.

The fire is extinguished after two hours during which the ammunition stores are flooded as a precautionary measure. Catastrofe sfiorata per incendio a bordo del caccia Decour.

Arson is blamed for the incident. A RAF weapon load carrier forming part of a convoy experienced a brake failure on an incline and overturned.

There was no damage to any nuclear weapon. Prima Bomba atomica francese. In late February in the Atlantic the USS Triton SSN , shortly after departure for a submerged global circumnavigation, suffers a leak in a main condenser circulating water pump, necessitating the shut down of the port reactor for five hours to effect repairs. In the beginning of March the USS Triton SSN , while traveling down the Atlantic, springs a severe leak in its starboard propeller shaft due to loose bolts and an improperly installed water seal.

The USS Triton SSN suffers a serious casualty in the after torpedo room when a hydraulic line to the stern plane mechanism bursts just prior to the end of its global circumnavigation. Quick action by crew members prevents the accident from getting out of control. The leak is stopped and hydraulic poweris restored.

The accident touches off a jet fuel fire on the Saratoga which is quickly extinguished. The fire scorches the vessel's amid ships hull. Un missile BOMARC "BO" per Boeing e "MARC" per Michigan Areonautical Research Center per la difesa aerea, immagazzinato in uno stato di pronto utilizzo per permetterne il lancio in due minuti, viene distrutto dopo l'esplosione di un serbatoio con elio ad alta pressione e la rottura del serbatoio di carburante del missile.

Anche se la testata viene distrutta dall'incendio, il dispositivo di sicurezza funziona correttamente e previene la detonazione della carica altamente esplosiva della bomba. Un articolo del New York Times descrisse, allora, uno scampato disastro nucleare, notando che il missile "si fuse sotto una fiamma intensa alimentata dal suo detonatore da 45,5 kg.

Le radiazioni seguenti "furono causate quando la parte metallica di magnesio e ossido di torio, che forma parte della bomba, presero fuoco". He took a capsule containing the source from the laboratory and put it in his left pants pocket for 5 hours, then shifted it around his abdomen and back for 15 hours. His whole body dose was 1,, rad, with 3, rad to the trunk. Symptoms of radiation sickness developed within hours, and he died after 15 days.

Sabotage is suspected in an incident involving damage to a shipyard fire hose used on board the USS Nautilus SSN for testing the ship's evaporators while the ship is undergoing overhaul at Portsmouth Naval Shipyard, New Hampshire. The Navy says, "No damage occurred to the ship. The fire starts from a leak in a high-pressure line that was pumping oxygen aboard.

The explosion occurs a few moments later. When dock unitsand boats are unable to bring the fire under control quickly, officers take the Sargo a short distance from the dock and deliberately submerge it with the stern torpedo hatch open to put out the blaze. The Navy says the ship's nuclear reactors weresealed off, and there was "absolutely no danger of an explosion from the reactor compartment.

The Sargo is the first nuclear ship in the Pacific Fleet and was scheduled to take the visiting King and Queen of Thailand on a cruise the next day. Luglio - Il sottomarino USS Theodore Roosevelt SSBN tenta di sbarazzarsi della resina consumata del proprio sistema di demineralizzazione utilizzato per eliminare le particelle ed i minerali radioattivi sciolti presenti nei circuiti refrigeranti primari.

Il mezzo resta contaminato quando il vento rigetta la resina nella sua direzione. Eleven of the Ammen's crew are killed and 20 are injured, and the ship is damaged beyond repair.

A Navy spokesman later says that the Edwards "apparently lost steering control" and its superstructure smashed into the Bennington's Number 3 elevator.

The destroyer is extensively damaged while the carrier is only slightly damaged. Navy minesweeper is swamped at Charleston, South Carolina. The Australian destroyer Anzuc accidentally fires a salvo into the hull of the Australian destroyer Tobruk opening a hole above the waterline during maneuvers off Australia. Un guasto al radar di NORAD provoca uno stato di massima allerta per un imminente attaco nucleare nemico. The K-8 hull was a Project November class submarine commissioned on 31 August On 13 October a loss of coolant accident occurred when a leak developed in the steam generators and an additional pipe.

Equipment for dealing with the leak was also damaged. The crew improvised a system to restore coolant to the reactor. During this time radioactive gases leaked into the entire vessel; radiation levels exceeded the maximum sensitivity of available monitors.

Three crew members suffered radiation injuries, with doses later estimated at rem. The submarine was returned to service; on 12 April the K-8 sank in the Bay of Biscay off Spain following an onboard fire. One man accidentally bumped a valve releasing the water onto himself and the others. Clothes and dosimeters were thrown away, making radiation measurement impossible. Questo piano di guerra consiste nel lanciare più di 3. Questo piano avrebbe dovuto esere sufficiente per uccidere un quarto della popolazione sovietica.

A Navy court of inquiry investigation later finds there were 42 small fires earlier in the year. The fire delays the ship's commissioning by several months to 27 October A seguito di un incidente dalle cause sconosciute, anche se pare che sia per un errato ritiro delle barre in un reattore sperimentale di Idaho Falls negli Stati Uniti, muoiono, durante l'esecuzione di attività di routine, tre tecnici John Byrnes, Richard McKinley et Richard Legg.

Non noto il numero di intossicati dentro e fuori l'impianto. Il reattore viene smontato; il nocciolo di 13 tonnellate e la vasca vengono ritirati alcuni mesi dopo.

The SL-1 reactor was a prototype of a reactor intended for easy assembly at remote facilities such as DEW line stations in the Arctic. Five aluminum-clad cadmium control rods provided reactor control. The SL-1 had operated 2 years, with an day shutdown for maintenance being completed at the time of the incident.

Three workers were reassembling the control rod drives on 3 January in preparation for startup the following day. The reactor became supercritical, with a total energy release of 1.

The worker who extracted the rod was killed instantly, impaled on the building's ceiling by a control rod. The other two men were burned and thrown by the steam explosion, one dying instantly from impact with a shielding block and the other sustaining head injuries of which he died 2 hours later maximum dose sustained was possibly rad.

The release of radioactive material was largely contained to the building. Emergency responders were alerted by an automated alarm and arrived at the site at 9: High radiation readings were measured in the reactor building, delaying entry.

One body was removed from the reactor building on 4 January and the other on 9 January. The reason that the control rod was withdrawn is unknown, since none of the workers survived and the facility did not have appropriate data recording systems. The control rods in SL-1 had some tendency to stick, sometimes causing difficulty during manual extraction.

One hypothesis is that the worker accidentally withdrew the control rod too far in an effort to overcome a stuck condition. The amount of withdrawal involved was about 50 cm, possibly difficult to achieve accidentally, and the particular control rod involved had not been sticking for the past six months.

Another hypothesis is that the rod was intentionally withdrawn in an act of murder-suicide; this was the conclusion of the investigation of the incident. The Oberon is refloated the next day without damage. A nuclear bomber on round-the-clock alert crashed on takeoff causing spilled fuel to erupt into flames which engulfed the aircraft at an undisclosed USAF base in Britain.

A nuclear weapon mounted on the aircraft's centerline pylon was badly damaged before the fire could be put out. According to secret correspondence to the Chairman of the U. Government has never acknowledged the accident and it is not included on the DoD's list of broken arrows.

A B bomber carrying one or more nuclear weapons was reported to have exploded in midair about 10 miles north of Monticello, Utah. Near Monticello the aircraft began climbing from 36, to 40, feet and soon experienced a violent bump followed by a descending right roll of about degrees, a short period of wings-level, nose-down flight, and then a violent spin.

Observers on the ground said the plane's left-wing engine caught fire, after which there was a midair explosion. Five crewmen were killed in the accident. Durante un allertamento aereo, un bombardiere B, che trasporta due bombe nucleari, a causa del cedimento strutturale dell'ala destra, va a pezzi a mezz'aria, uccidendo i tre membri dell'equipaggio: Il paracadute di una delle due bombe si apre correttamente con danno finale minimo.

Il secondo paracadute della bomba, invece, funziona male e la bomba si squarcia a pezzi nell'impatto con il terreno, spargendo i suoi componenti su un'area estesa. Secondo Daniel Ellsberg, la bomba avrebbe potuto accidentalmente esplodere perché "cinque dei sei dispositivi di sicurezza avevano fallito". Anche il fisico nucleare Ralph E. Lapp conferma questa ipotesi, sostenendo che "solo un unico interruttore" ha "impedito alla bomba di detonare e di spargere fuoco e distruzione sopra un'ampia area".

I 24 megatono della bomba rappresentano una potenzialità magiore rispetto a tutto l'esplosivo usato in tutte le guerre della storia.

Il presidente degli Stai Uniti Kennedy, allertato sull'incidente a Goldsboro del 24 gennaio dello stesso anno, viene informato che vi erano stati più di 60 incidenti che coinvolgevano armi nucleari dopo il , di cui due riguardanti missili antiarerei con testata atomica realmente lanciati per inavvertenza.

Un bombardiere B con due armi nucleari, si schianta durante una missione di addestramento. Nessuna esplosione e nessuna contaminazione. The Royal Navy diesel submarine HMS Finwhale arrives in the Firth of Clyde, Scotland, with a six-by-two-foot hole in her casing caused by heavy seas in a gale as she sailed to the Arctic for underwater tests. A dent on the aluminum casing forward of the sail measures 20 by 6 feet.

One sailor is killed and one hurt when a steel cable whiplashes during an attempt to free the ship. The ship is subsequently scuttled. La fuoriuscita di radiazioni per un guasto al sistema di controllo di uno dei due reattori di un sommergibile atomico sovietico provoca la morte del capitano e di sette membri dell'equipaggio. On 4 July a leak developed at an inaccessible part of the primary cooling circuit, causing a sudden pressure drop and triggering emergency systems.

The crew improvised a system to supply coolant, involving prolonged exposure to radioactive steam and other gases in the reactor compartment. Eight crew members sustained doses of 5, to 6, rem; the rest of the crew sustained significant doses as well at least rem. A diesel submarine evacuated the crew, and the K was towed back to the Kola Peninsula.

For the eight crewmembers with fatal doses, time from exposure to death in days was 6, 6, 6, 8, 9, 11, 16, and The remaining crew were hospitalized with radiation sickness until September. Replacement of the reactor compartment was completed from to , and the two damaged reactors were dumped in Abrosimova Bay in the Kara Sea.

The munitions ship Save runs aground and explodes off Mozambique. Operators failed to identify the cause of the radiation readings and resumed operations. An operator turned on the vacuum pump again, producing a criticality excursion accompanied by a flash of light; the operator turned off the pump and went to a telephone to alert a supervisor.

He developed mild radiation sickness from a dose of rad. The oil reservior was finally drained July. Navy tanker catches fire and explodes while in port at Morehead City, North Carolina, killing one. Flames from the burning ship threaten seven huge storage tanks containing more than ten million gallons of high octane aviation fuel. Two sailors seal themselves in the flooded compartment and save the submarine and its 76 crewmen by manning the controls until the submarine surfaces.

The collision ruptures a gasoline line on the carrier causing a flash fire which is extinguished in less than five minutes. La Bomba "Zar", la regina delle bombe, fu la bomba H più potente.

La bomba venne lanciata da un bombardiere Tu pilotato da A. Durnovtsev, diventato un eroe dell'Unione Sovietica. Il soprannome di "Bomba Zar" gli venne dato dagli americani per qualificare il progetto come inutile poichè esisteva già il cannone più grande al mondo, lo Zar Pushka.

Si riporta che la bomba potesse infliggere ustioni di primo grado anche a km. La distruzione è totale in un raggio di 25 Km e le costruzioni sono seriamente danneggiate fino a 35 Km. Si ignora quali potrebbero essere i danni anche a più grandi distanze, ma è probabile che, in caso di vento i suoi effetti si sentirebbero anche a 1. Its reactor is shut down and a diesel generator is started up to provide electricty in keeping with usual docking procedures.

But after seven or eight hours of operation the diesel generator breaks down. While sailors work on the generator, electricity is provided by an electric storage battery. The generator takes much longer than expected to repair, however, and so the decision is made to restart the reactor. But, a nuclear reactor takes several hours and considerable electricity to restart, and the Thresher's battery is depleted before the reactor becomes critical.

With no electricity to keep the ventilation system going, the submarine starts to heat up. Temperatures in the machinery spaces reach approximately degrees. Some men are ordered out suffering from the heat and fumes, and the captain fears the heat and humidity could damage electrical equipment and lead to a general evacuation. Ultimately the problem is solved by hooking up electrical cables to the diesel-electric powered submarine Cavalla SS which is moored along side early the next morning.

With electricity from the Cavalla, the Thresher's reactor is able to be restarted. Pare che non ci sia stata alcuna contaminazione risultante dall'incendio. The Falmouth is holed above and below the waterline, but returns to Portland, U. The Tide Flow suffers superficial damage. Un test sotterraneo con esplosione nucleare, libera nuvole impreviste di vapori radioattivi.

A rocket motor aboard the USS Meredith DD ignites and burns on its launcher, causing an intense fire of short duration, while the ship is at Mayport, Florida. The commander of the destroyer squadron to which the Meredith is attached says that safety features prevented the rocket from leaving the ship. In an accident in the nuclear power plant of an early class of Soviet nuclear-powered ballistic missile submarine probably a Hotel class reportedly occurs near the coast of England while ship is returning from a training exercise.

Crew members were seriously contaminated and parts of the ship and its missiles were also contaminated when a cooling pipe broke. The level of radiation is reported to have been five roentgens per hour in the space where the pipe broke.

After a two-month ventilation of the submarine, a decision is made to transfer the missiles to two diesel-powered submarines for their test launches. Western intelligence sources report that a submarine belonging to the United States or another NATO power was damaged and forced to the surface by a megaton underwater nuclear test blast set off by the SovietUnion in the Barents Sea.

The detonation point is said to have been about miles from the submarine whose commander is quoted as saying, "If we had been much closer we might not have survived.

The accident damages one of the Balao's mast headlights, punches two small holes in the superstructure supporting the periscope, and breaks one radar antenna and damages another.

Four family members died of resulting radiation sickness: Radiation exposure was not identified as the cause of the deaths until July-August. The father survived with lesser symptoms. Estimated doses for the four who died were 4,, rad, 3, rad, 3, rad, and 2, rad; dose to the father was about , rad. Criticità di incidente con soluzione di plutonio An accident at a plutonium processing plant resulted in a criticality accident. Plutonium solution was spilled onto the floor of a solvent extraction hood.

Improper operation of valves allowed a mixture of plutonium solutions in a tank that became supercritical, prompting criticality alarms to sound and subsequent evacuation of the building. Exact details of the accident could not be reconstructed. The excursion continued at low power levels for Criticality was probably terminated by precipitation of plutonium in the tank to a non-critical state. Three people had significant radiation exposures , 43, and 19 rem.

The West German training diesel submarine Hai sinks in the North Sea in feet of water miles northwest of Wilhelmshaven, West Germany, during a storm, killing A week later cracks are reported to be found inthe steel hull similar to cracks found in other nuclear submarines built in Britain.

The cracks occur in thick steel welding. The Navy has known about the cracks ever since it was discovered that the original specification for steel for the submarines was not of high enough standard. The cracks do not mean the submarines will not go to sea, but if there are too many the metal will have to be rewelded.

And, if cracks develop quicker than expected, Polaris submarines would require excessive amounts of welding when they come in for refits between patrols. Ottobre - Lagoona Beach Usa.
