12, About seven safety tests (not listed in Table 1) bre
planned:
Five one-point safety tests, in which a device
will be detonated by use of only one detonator in order
to simulate a "one-point" detonation of the type which
could occur in an accidental crash,
fire, or similar
accident. The purpose of these tests is to determine
whether any nuclear yield would result from accidental
detonation.
Two safety tests for determining plutonium hazards
resulting from (1) one-point non-nuclear detonation of
the sealed-pit implosion warhead pnryepep, and (2)
purning of plutonium,
