Wie ae We also recommend that a test of a device using U-223 be made as s00n as practicable when a sufficient quantity is available. 2, isvoratt Nuclear Propulsion Program, The pressure of time, and the ' Anjection of the U-233 problem into our agenda at a very late date, com- - bined with the lateness of the Commission request for further elaboration of olir comments on the ANP program as given in the report of the Chairman of the GAC dated June 3, 1954, made it impossible to study the ANP problém in greater detail at this meeting. However, the Subcommittee on Reactors proposes to meet at Oak Ridge for three days, September 21, 22, and 23, | 1954, to consider the whole ANP program and hopes that the Commission will invite attendance at this meeting of representatives of the Nuclear ‘Development Associates and the General Electric Company, as well as AEC |” staff and other interested parties. We hope that a report, which may be useful to the AEC, will result from this meeting._—____~ \ We wish to reiterate our belief in the importance of the ANP program for our national defense, and our hope that it can be so organized as to proceed to its objectives with minimum delay, ‘ 3. Comments on the Discussions of July 12, 13, and 14, Jointly with the © MLC and the CCAE, we had three days of review and discussion at. Sandia and Los Alamos with the principal staffs of Sandia Corporatioa, LASL, and Livermore Laboratory. (a) Sandia. oO We were impressed with the strength of the organization for engineering development and design, and the great ettention which was given by the organization to reliability and effectiveness in weapon designs. Significant progress was reported in the developmen of fuses in the direction of reliability and simplicity.: . We noted with special interest and approval the careful effort which is being made in system studies toward understanding thenature of weapon systems which make for maximum effectiveress, We were also gratified to observe the close and friendly cooperation of Sandia with LASL and with the military cvganizations. (») Los Alamos, DOE ARCHIVES The day and a half of briefing and discussior. by the staff of Los Alamos was illuminating and complete, We heard from: Dr. Graves on the CASTLE tests and the future TEAPOT, Post-TEAPOT, WIGwM, and REDWING: estes a. Schreiber on present weapon status, nuclear safing and SR J Dr. MacDougall on tactical and saalt weapons, and also on § CASTLE and forward-locking prospects in two-stage weapons, and also ca the use of "dirty" plutonium; and, finally, Dr. Bradbury on future directions in weapon design, utilization and stockpiling.
