E FY ANYNHR ASey MPgtaectoEEape 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, - 13, Preliminary plans are being made for Operation HARDTACK, scheduled for the Ground, spring of 1958, at the Eniwetok Proving The Enivetok Proving Greund Technical.
