Because the

required extensive cryo-
genic (low-temperature) facilities for the special handling of
liquid hydrogen, the AEC and the DOD had previously agreed that
the first attempt at designing a deliverable thermonuclear weapon
for emergency capability would be based on "dry" rather than "wet"
(eryogenic) principles,. The design of such a deliverable weapon,
BELETED
avoids the cryogenic problems by incorporating
deuterium in dry hydride form (lithium 6 deuteride).,
The lithium
6 would abserb neutrons during the explosion and be converted to
tritium, which would react with the deuterium to produce highenergy neutrons which would cause fission of natural ureniun.
