Comparative fireball radii for a selection of nuclear weapons. [citation needed] Contrary to the image, which may depict the initial fireball radius, the maximum average fireball radius of Castle Bravo, a 15-megatonne yield surface burst, is 3.3 to 3.7 km (2.1 to 2.3 mi), [6] [7] and not the 1.42 km displayed in the image.
Castle Bravo was the first in a series of high-yield thermonuclear weapon design tests conducted by the United States at Bikini Atoll, Marshall Islands, as part of Operation Castle. Detonated on 1 March 1954, the device remains the most powerful nuclear device ever detonated by the United States and the first lithium deuteride -fueled ...
English: A simple graphic showing comparative nuclear fireball radii for a number of different tests and warheads. From largest to smallest, the diameter are: Tsar Bomba — 50 Mt — 4.6 km (2.9 mi) Castle Bravo — 15 Mt — 2.84 km (1.76 mi) W59 warhead (Minuteman missile) — 1 Mt — .96 km (0.60 mi)
But as was discovered in the first test of this type of device, Castle Bravo, when lithium-7 is present, one also has some amounts of the following two net reactions: 7 Li + 1 n → 3 T + 4 He + 1 n 7 Li + 2 H → 2 4 He + 1 n + 15.123 MeV. Most lithium is 7 Li, and this gave Castle Bravo a yield 2.5 times larger than expected. [16]
Castle Bravo detonation, 1st Mar 1954 The liquid deuterium fuel of Ivy Mike was impractical for a deployable weapon, and the next advance was to use a solid lithium deuteride fusion fuel instead. In 1954 this was tested in the " Castle Bravo " shot (the device was code-named Shrimp ), which had a yield of 15 Mt (63 PJ ) (2.5 times expected) and ...
Veteran finance CEO Sallie Krawcheck is pulling back from the $2.4 billion investment platform she co-founded a decade ago and has appointed co-CEOs to stand in her stead at Ellevest, she ...
The Castle Bravo shot of 1 March 1954, at Bikini Atoll, was the first test of a deployable (solid fuel) thermonuclear weapon, and also (accidentally) [citation needed] the largest weapon ever tested by the United States (15 megatons). It was also the single largest U.S. radiological accident in connection with nuclear testing.
