OFFICE OF NUCLEAR REACTOR REGULATION REQUEST FOR ADDITIONAL INFORMATION RELATED TO REACTOR EQUIPMENT COOLING SYSTEM NEBRASKA PUBLIC POWER DISTRICT COOPER NUCLEAR STATION DOCKET NO. 50-298 By letter dated March 24, 2008 (Agencywide Documents Access and Management System Accession No. ML080910062), Nebraska Public Power District, the licensee for Cooper Nuclear Station, requested a license amendment to revise Technical Specification 3.7.3, Reactor Equipment Cooling (REC) System.
The Operator Licensing and Human Performance Branch (IOLB) staff performed an initial review of the license amendment request (LAR) in the area of human performance. The licensees responses to the following request for additional information with regard to the human performance aspects of the license amendment are needed for the IOLB staff to complete its review.
- 1.
The LAR stated that operator action to align the Service Water (SW) system to the REC critical loops following a loss of the REC system during a loss of coolant accident (LOCA) can be performed within an hour. How much time does the operator actually have available to realign the SW system to provide cooling to the Emergency Core Cooling System pump rooms if the REC system is not available or determined to be inoperable during a LOCA? How was the one hour time frame determined? Does the assumed available time of one hour bound the recent (June 30, 2008) Measurement Uncertainty Recapture power uprate approved by the NRC?
- 2.
Discuss whether the operating crews will have an opportunity during operator training to perform a variety of scenarios involving the recognition of the loss of the REC system and realignment of the SW system to the REC system (in addition to long-term recovery from a LOCA).
