WASHINGTON PUBLIC POWER SUPPLY SYSTEM NUCLEAR PROJECT H0. 2 DOCKET NO. 50-397 LICENSE NO. CPPR-93 10CFR50.55(e) CONDITION #251 LIMITORQUE MOTOR OPERATORS WITH HOTORS FROM BALDOR ELECTRIC COMPANY FINAL REPORT Description of Deficiency i

Motor operated valves were received from the manufacturer with unqualified l

motors by Baldor Electric Company. Condition was discovered after valves were installed during equipment qualification group walkdown to obtain nameplate data on March 24, 1983. The valves involved are SW-H0-187A, -1878, -188A, and

-188B.

Safety Significance Valves SW-M0-187A and B and SW-M0-188A and B are Service Water System (SW) iso-lation valves at the interface with the Reactor Closed Cooling Water System (RRC) to provide an alternate cooling water source for the fuel pool cooling heat exchangers FPC-HX-1A and IB. The valves will allow utilization of the seismic Class I service water system for FPC cooling in the event of an earth-quake. Operation of the valves is not required for normal plant operations, but only under emergency conditions. The unqualified motors would have the potential for jeopardizing corrective action to meet emergency conditions and the deficiency is, therefore, considered reportable.

Cause for the Deficiency Error on the part of the manufacturer in that Limitorque supplied motor opera-tors to WNP-2 with motors that were not qualified to IEEE 382 - 1972.

Corrective Action The manufacturer, Limitorque, has been made aware that the motors were impro-perly supplied and is to replace the existing motors with units qualified to IEEE-382-1972 meeting requirements of NUREG-0588 Category II. Startup Defici-ency Reports (SDR) #8308, 8309, 8310, and 8312 have been issued to identify the deficient condition. The new qualified motors have been received from the manufacturer, but the physical replacement of the motors has been deferred until no later than the first refueling outage. This decision is based on the 4 ser-vice water valves identified are part of the fuel pool cooling modification, which has been deferred.

Action to Prevent Recurrence The vendor has pri. nary responsibility for assuring that components supplied correlate with the qualification records submitted to substantiate their suita-bility for the service designated.

The Supply System Equipment Qualification Program represents a complete review of safety-related equipment relative to environmental and seismic qualification.

This program assures that components are qualified for their design service conditions and will preclude unqualified components in completed plant installa-tions, unless justified by specific evaluation, such as the J10.
