.. a Docket No.: 50-312 Mr. Joe Firlit Chief Executive Officer, Nuclear Rancho Seco Nuclear Generating Station 14440 Twin Cities Road Herald, California 95638-9799
SUBJECT:
REACTOR COOLANT PUMP TRIP FOR RANCHO SECO (TAC No. 49680)
Dear Mr. Firlit:
For the reactor ccolant pump (RCP) trip issue defined in the TMI Action plan item II.K.3.5 (Multiplant Action G-01), the staff generically approved the Babcock & Wilcox Owners Group (BWOG) methodology in Generic Letter 86-05, with the condition that plant-specific information needs to be addressed. Our review of the Rancho Seco plant-specific information has progressed to a degree that we can conclude that implementation of the BWOG methodology has signifi-cantly improved the reactor safety, and there are no major safety-significant concerns for the plant-specific information.
Accordingly, we have completed our review of your plant-specific RCP trip setpoint development and find it acceptable. This issue may be the subject of on-site verification.
Sincerely,
/s/
