The most notable event of Operation Castle was the Castle Bravo test. The dry fuel for Bravo was 40% Li-6 and 60% Li-7. Only the Li-6 was expected to breed tritium for the deuterium-tritium fusion reaction; the Li-7 was expected to be inert.
Path of the nuclear fallout plume after the Castle Bravo test: the large plume lead to evacuations of additional atolls.
