Because the yields for many tests at `` Operation Castle '' in 1954 were dramatically higher than predictions , `` Redwing '' was conducted Action using Using an `` energy budget '' : There were limits Limiting to the total amount of energy released , and the amount of fission yield was also strictly controlled Control .

Fission , primarily `` fast '' fission of the natural uranium tamper surrounding Surrounding the fusion capsule , greatly increases Cause_change_of_position_on_a_scale the yield of thermonuclear devices , and constitutes the great majority of the fallout , as nuclear fusion is a relatively clean reaction .

The bomb 's yield was estimated at , far below its designed capability .

Its yield made it Causation technically a megaton weapon Bearing_arms .

Its yield was a very disappointing .

This time the yield of exceeded Cause_change_of_position_on_a_scale expectations .

This was a true hydrogen bomb , but most of the yield came from nuclear fission rather than nuclear fusion .

With an explosive yield of about , it remains Presence the largest British nuclear weapon ever tested Testing .

The design of Grapple Y was notably successful because much of its yield came from its thermonuclear reaction instead of fission of a heavy uranium-238 tamper , making it Causation a true hydrogen bomb Attack , and because its yield had been closely predicted—indicating that its designers understood Know what they were doing .

The design of Grapple Y was notably successful because much of its yield came from its thermonuclear reaction instead of fission of a heavy uranium-238 tamper , making it Causation a true hydrogen bomb Attack , and because its yield had been closely predicted—indicating that its designers understood Know what they were doing .

Castle Bravo 's yield was 15 megatons of TNT , 2.5 times the predicted 6.0 megatons , due to unforeseen additional reactions involving Cause_to_be_included Li , which led to Causation the unexpected radioactive contamination of areas to the east of Bikini Atoll .

A fleet of 95 target ships was assembled Come_together in Bikini Lagoon and hit Attack with two detonations of Fat Man plutonium implosion-type nuclear weapons of the kind dropped on Nagasaki , each with a yield of .

Operation Dominic was a series of 31 nuclear test Testing explosions with a 38.1 Mt total yield conducted Action in 1962 by the United States in the Pacific .

The bulk of the object 's energy was absorbed by the atmosphere , with a total kinetic energy before atmospheric impact Influence estimated from infrasound and seismic measurements to be equivalent to the blast yield of 400–500 kilotons of TNT ( about 1.4–1.8 PJ ) range – 26 to 33 times as much energy as that released Causation from the atomic bomb detonated Attack at Hiroshima .

Because of the secretive nature of North Korea and small yield of the test Research , there remains some question as to whether it was a successful test Research of an unusually small device ( which would have required Preventing_or_letting sophisticated technology ) , or a partially failed Confronting_problem `` fizzle '' or dud .

A scientific paper Statement later estimated the yield as 0.48 kilotons .
