WNP-2 Supplemental Sa fe ty Evaluation R eport 6.3.2.3 Emergency Core Cooling Systems Functional D esign With regard to provisions to protect the low pressure emergency core cooling systems from overpressurization by the reactor coolant systems the staff's position is that one of the three options discussed in Section 6.3 of the Standa rd R eview Plan (NUR EG-0800) be implemented.
In letters dated July 28, 1982, and September 28,1982, f rom G.D. Bouchey (Washington Public Power Supply System - WPPSS) i to A.
Schwencer (NR C), the applicant committed to a modification tc the control logic on the pressure interlocks for the lo w pressure ECCS injection valves.
The new togic will permit opening of the moter operated isolation valve only when the reactor coolant pressure is below the design pressure of low pressure system i
involved.
The interlocked valver in series with a check valver is censistent with the guidelines of the Standard R eview Plan.
The applicant has also committed to implementing this change by fuel load.
Based upon the conceptual design and schedule commitment discussed hereine but conti.ngent upon an amendment to the FSM in this regarde we find the applicant's preposed modification acceptable.
