ADVISORY COMMITTEE ON REACTOR SAFEGUARDS NUCLEAR REGULATORY COMMISSION WASHINGTON. D. C. 20555 November 16, 1976 Dr. G. Paulson Assistant Comnissioner for Science Department of Enviromnental Protection State of New Jersey Trenton, NJ 08625
Dear Dr. Paulson:
The Advisory Conmittee on Reactor Safeguards has considered your request for comments on the preliminary analysis by Mr. Peter Davis of the prob-ability of a catastrophic accident during the remaining lifetime of the Oyster Creek plant. It is unfortunately not :possible for the ACRS to provide a detailed review of this study.
W:! note, however, that Mr. Davis suggests that the incor:poration of the automatic recirculation pump trip would lead to a substantial reduction in the probability of a core melt following a failure to scram on an anticipated transient.
The ACRS has been following closely the continuing evaluation of the matter of anticipated transients without scram (ATWS) since the question was raised by this Committee several years ago. The recirculation pump trip feature is included in ioost, if not all, of the newer boiling water reactors in operation or under construction, and in March 1976 the ACRS recormrended that this feature be implemented pranptly on all operating BWR's unless analyses have shown that such a trip is not required to mitigate the consequences of ATWS.
we understand that the Jersey Central Power and Light Conpany has made a comnibnent to install such a pump trip unless they are able to provide a convincing demonstration that other features incorporated in this plant make this trip unnecessary (see attachments).
