Dear Mr. Crutchfield:

Subj ec t : Oyster Creek Nuclear Generating Station Docket No. 50-219, SEP Topic III-5B Pipe Break Outside Containment By this letter, we transmit the enclosed report entitled " FRACTURE MECHANICS ANALYSIS OF THE OYSTER CREEK NUCLEAR GENERATING STATIOP EMERGENCY COOLING SYSTEM" dated April 20, 1982.

An evaluation by Jersey Central Power & Light Company (JCP&L) and the NRC site inspection in 1980 identified a potential damage to the emergency condenser isolation valves and controls following a pipe break on the 75' elevation of the reactor building.

JCP&L letter to the NRC dated September 30, 1981 stated that an analysis to demonstrate that the emergency condenser piping will leak before a significant break could occur was to be performed.

Our analysis indicates that the 75' elevation piping satisfies " leak before break" criteria recently developed by the NRC.

The results and the detailed description of the analysis are given in the enclosed report.

Very truly yours,

/
