MEMORANDUM TO: E. L. Jordan, Director
Division of Emergency Preparedness and Engineering Response
FROM: Dennis F.- Kirsch, Director
Division of Reactor Safety and Projects
SUBJECT: POTENTIALLY GENERIC QUESTION ON RESIDUAL HEAT REMOVAL (RHR)
PUMP RUNOUT FOR WESTINGHOUSE REACTORS DURING RECIRCULATION
PHASE
Inspection Report 86-32 for the Trojan Nuclear Power Plant identified a
finding that with a single failure of.a RHR pump during the recirculation
phase af ter a Loss of Coolant Accident (LOCA), there was a potential for RHR
pump cavitation (See Enclosure for details). As the report indicates the
question of generic applicability was-asked of Westinghouse by the Trojan
licensee and there was indication that similar problems occurred or were
possible at other facilities. The ' result of a loss of all RHR flow (a single
failure and the other train failure due to cavitation or runout) is obviously
significant as it would result in the loss of all recirculation flow
following a LOCA. Actions taken by the Trojan licensee are specified in the
Enclosure. Inspection of the other, similarly designed Westinghouse plants
in the region (Diablo Canyon) concluded that because of procedural
differences that Diablo Canyon was not susceptible to the problem.
Contact for the Trojan licensee is Gary Zimmerman, telephone number: (503)
226-8119, address: Portland General Electric Company, 121 S. W. Salmon
Street, Portland, Ores,on 97204.
