ABWR QUARTERLY PROGRESS REPORT FOR OCTOBER 1 TO DECEMBER 31, 1959. VOLUME I. SL-1 OPERATIONS AND EVALUATION

Technical Report · Fri Jan 15 04:00:00 EST 1960

OSTI ID:4175562

During the report period the SL-1 plant suffered 10 unscheduled shut- downsi four were the result of steam leaks, two resulted from instrumentation, and two were caused by turbine governor malfunction. Rod bank position; were obtained for various xenon conditions. Decay heat removal tests established that the system pressure buildup would not result in relief valve lifting following a scram and complete loss of power. The shield cooler performance was evaluated. Four nuclear power level channels were calibrated against a reactor thermal heat balance. The process flow dlagrams were completed and equipment specifications were prepared. A filter was installed in the branch feedwater line for rod sealing and cooling to prevent crud accumulation in the control rod drive labyrinth seals. An instrument to permit hot calibration of the reactor water level instruments was constracted. The feedwater control system was mcdified to single element control. (See also IDO-19006.) (W.D.M.)
