MEETING

SUMMARY

OF MAY 21,1998, REGARDING EMERGENCY CORE COOLING SUCTION STRAINER MODIFICATIONS (TAC NO. M96146)

On May 21,1998, representatives of the New York Power Authority (NYPA) met with members of the Nuclear Regulatory Commission (NRC) staff in Rockville, MD. The licensee had requested this meeting in order to brief the NRC staff on plans for modification of emergency core cooling system (ECCS) suction strainers at the James A. FitzPatrick Nuclear Power Plant (JAF). These modifications are being made to respond to Bulletin (B) %-03, " Potential Plugging of ECCS Suction Strainers by Debris." A list of attendees is provided in Enclosure 1. A copy of the handout provided by NYPA is provided in Enclosure 2.

NYPA plans to install new ECCS suction strainers during a JAF refueling outage scheduled to begin October 16,1998. The existing residual heat removal, core spray, and high pressure coolant injection strainers will be replaced with large stacked disk strainers. NYPA also plans to replace the reactor core isolation cooling system suction strainer.

NYPA indicated that following installation of the new strainers, it plans to desludge the suppression pool every other refueling outage. The NRC staff stated that the licensee needs to ensure that the suppression pool cleaning frequency is sufficient to ensure the strainer design basis assumptions for sludge and foreign material accumulation are not exceeded.

NYPA noted that its calculations of available ECCS pump net positive suction head assumed that 2 psi containment overpressure is available throughout an event. NYPA stated it believed using this overpressure credit is consistent with the original plant design basis as accepted by the staff in its safety evaluation of November 20,1972. However, it was noted that is not clear what duration for this credit was proposed by the licensee and accepted by the staff. NYPA and the NRC staff plan to review the licensing basis to clarify usage of the overpressure credit.

The NRC staff and NYPA discussed what information will be required to provide the staff with an adequate description of the suction strainer modification. The licensee presently expects to make the modifications under 10 CFR Part 50.59, so that prior approval by the NRC staff would not be required. Overall, the staff believes the new strainer installation provides a net safety benefit. The staff stated that it would like to receive information sufficient for confidence that the new strainers do not create any safety issues. )
