i, Argonne Reactor Program -~ Boiling Reactors, At this Meeting the Committee heard a report from its Subcommittee on Reactors covering a three-day set of detailed and thorough briefings by Dr. Zinn and his associates at ANL during the preceding week. This study was undertaken. so that the Committee could respond to the General Manager's request for an appraisal of the boiling water reactor development being carried out as part of the ANL reactor program. , ‘We wish to endorsethe general programoutlined by Dr, Zinn, includ= ing the long-range development of the fast breeder reactor. In the following, we comment specifically on the boiling reactor program. Present plans call for testing the existing boiling reactor instal~ lation at Arco under conditions of high operating power leading to destructive melting of the fuel elements. Further tests will be carried out on a new and improved installation this fall, It was also noted | that a tentative schedule has been established for constructing, at the Argonne National Laboratory, an experimental boiling reactor (EER) capable of delivering five megawatts of electric power, This schedule provides for construction to begin April 1, 1955, and for the reactor to go critical by the end of 1956. The component tests and studies, outlined by Dr. Zinn, on fuel element design, corrosion, burn up, the use of radioactive steam in turbines, andchemical costs are integral and essential parts of this progran. The Committee continues to believe that the boiling water reactor | development program is one of great promise, We recommend continued strong support, with arrangements which will minimize contractual delays. In otir study of this subject we have been reminded of the importance of maintaining a flow of information between different groups with common technological interests; and ye hope that arrangements can be made to ' facilitate the exchange of technical reports between ANL, Hanford, and Savannah River. . . / A more detailed report is being prepared by the Subcommittee and will be available at a later date, 5. ~ The Meeting was the last meetingof the General. advisory Committee before the terms of office of Dr. Buckley, Dr. von Neumann, and Dr, Rabi expire, It was therefore impossible to fix a definite date for the next. | meeting. 1954. However, a tentative date was set for October 4, 5, and 6, ‘ In any event the meeting will occur in a perlod between October lst and October lith, Among other matters, the Commtise hopes to discuss weapons effects, and Project Sunshine,
