The purpose of the test was to determine the station operating characteristics during a start-up with all reactor coolant loops initially cold, requiring chemical addition and the turbine cold. The plant was successfully taken from a cold condition to generator synchronizing in accordance with Volume I, Chapter 43, Station Start-up no. 1. Twice during the test malfunctioning equipment delayed the completion of the test. The 1B boiler drum level indication required repair work and the 1D loop was removed from service due to pump failure. This required completing the test with only two coolant loops in service.

Description
The purpose of the test was to determine the station operating characteristics during a start-up with all reactor coolant loops initially cold, requiring chemical addition and the turbine cold. The plant was successfully taken from a cold condition to generator synchronizing in accordance with Volume I, Chapter 43, Station Start-up no. 1. Twice during the test malfunctioning equipment delayed the completion of the test. The 1B boiler drum level indication required repair work and the 1D loop was removed from service due to pump failure. This required completing the test with only two coolant loops in service. Comment on start-up procedure is that there exists a minimum of 2 to 3 hours between steps 35 to 36 to deoxygenate the Condensate System. For step 31b, the excessive nuclear level trip setting in normal setting (175%) can not be readjusted with reactor power level above 1% at an average coolant temperature of 400 F. The limiting temperature is 480 F. Blanket and seed flow recorders (CIP) need calibration which will be done upon completion of the test.
