Dear Sir:

Subject:

Oyster Creek Nuclear Generating Station Docket No. 50-219 SEP Topic V-10.A In response to Mr. Ziemann's letter dated December 13, 1978, which was received by Jersey Central Power S Light Company on December 19, 1978, concerning your staff's evaluation of SEP Topic V-10.A, Residual Heat Removal System Heat Exchanger Tube Failures, the evaluation has been reviewed with the following comments:

1. On Page 3, the second paragraph, it should be noted that the throttling of the Reactor Building Closed Cocling Water (RBCCW) flow is done following the securing of shutdown cooling but is isolated during normal operation. +
2. No mention is made in the evaluation of the connection between the Shutdown Cooling Systems and the Process Steam System. This could provide a possible leakage path if the process steam isolation valves leak.

An engineering request has been generated to cut and cap these lines.

Very truly yours, l
