~ll1954.) - He said that detailed shot programs had been requested from Los Alamos and Livermore for early December review. It was hoped that the GAC would review them as soon as possible, At 2:00 p.m. Col. V. G. Huston and Col, R. D. Gahl entered the meeting. With regard to possible duplication in the three case tests scheduled for TEAPOT, Gen. Fields said that Dr. Bradbury and Dr. York had discussed them and felt all three were warranted, To minimize fall-out incidents, the large shots will be interspersed between small shots. weather criteria are met. Shots will be made only when rigid The operation will be difficult, and long delays (for good weather) in the big shots may be anticipated. _ Gen. Fields said that a smaller operation may be desired in enSee 7 8 peed eaawmeeeS - Possible Tests, Fall 1955 Jeapon Effects Presentation Nevada in the fall. The purpose would be to test the nuclear safety of sealed designs. At 2:10 p.m. Dr, Herbert Scoville, of AFSWP, joined the meting to discuss weapon effects. Dr. Scoville first displayed curves of "scaled crater radius vs scaled sharge depth" (radius/wi/3 vs depth/?/3) for TNT and for nuclear explosions, In general the cratering effect of nuclear shots is much less than that of INT shots of the same energy release, because of the diversion of energy into non-effective forms. At the surface a 10 MT shot is expected to give a 2700 ft diemeter crater
