OLEN ELLYN, ILLINOIS 90137 OCT 101986 MEMORANDUM FOR: DRP Technical Personnel FROM:
Charles E. Norelius, Director, Division of Reactor Projects
SUBJECT:
CLARIFICATION OF REPORTABILITY PURSUANT TO 10 CFR 50.72 AND 10 CFR 50.73 On September 5, 1986, Quad Cities discovered that the discharge valve on the Reactor Core Isolation Cooling System (RCIC) pump would not open remotely.
This failure, by itself, would have prevented RCIC from perfonning its design function. Historically, the licensee has reported RCIC system failures pursuant to 10 CFR 50.72 and 50.73; however, following the September 5 event, they questioned whether the event was reportable in light of the fact that RCIC is not a system taken credit for in their accident analysis, and is not needed for safe shutdown.
On September 5 this question was posed to Mr. J. Rosenthal, Chief Events Analysis, Branch, IE and Mr. E. Weiss of his staff. Their response was that RCIC inoperability alone, for whatever reason, was not reportable pursuant to either 10 CFR 50.72 or 50.73 provided that the licensee has not taken credit for RCIC as either an Engineered Safety Feature or in their safe shutdown analysis. Resident inspectors are requested to discuss this matter with their licensees.
