【 摘 要 】

The purpose of this report is to provide initial scoping for follow on work designed to improve nuclear plant operation. The focus of this report is twofold. Selected trips over the last five years are examined to determine if there are potential opportunities to automate tasks that are currently performed manually. The second area is to evaluate the potential for avoiding reactor trips by reducing power in a controlled manner upon the loss of turbine generator load. Some candidate opportunities to reduce the frequency on reactor trips identified in this report are redundant feedwater controls, automated response to a feedwater or condensate pump trip reducing power vice a reactor trip, and elimination of air operators for the feedwater control valves or providing redundant air supplies.
