Title: ARMY GAS-COOLED REACTOR SYSTEMS PROGRAM. Quarterly Progress Report, Januart 1, through March 31, 1963

Abstract

The scheduled modification of the ML-1 power plant was completed and the plant was operated continuously for 101.3 hr. The maximum reactor power was 3.2 Mw(t) and the maximum shaft output power was 252 kw. The plant performed essentially as predicted. The tube sheets temperatures were lower than predicted, indicating that the bypass flow corrective modification was successful. Evidence of a leak between the process gas and moderator systems was observed shortly after shutdown. Investigation confirmed the presence of a leak in the lower plenum and a program for partial disassembly of the reactor to locate and repair the leak was initiated. The TCS 670A failed during open cycle testing because of insufficient clearances in the turbine. A program of modification and repair was initiated. The development testing of the alternator was essentially completed; the alternator will deliver 400 kw with a 45 kvar per phase external capacitance. Start motor development was completed. The investigation of the embrittlement of the IB-8T-1 fuel pin cladding continued. It was tentatively concluded that the X-phase formation resulted from nitrogen inside the pins. No evidence of X-phase was found in preliminary examinations of IB-8T-2 cladding. The IB-17R (ML-1-II prototype) in-pile tests were initiated. (auth)
