Subject:

Three Mile Island Nuclear Station Unit 1, (THI-1)

Decket No. 50-289 Operating License No. DPR-50 GPU Nuclear Schedule for Responding to NRC Request for Additional Information Regarding Generic Letter (GL) 90-06,

" Resolution of Generic Issue 70, ' Power-Operated Relief Valve and Block Valve Reliability,'and Generic issue 94,

' Additional Low-Temperature Overpressure Protection for Light-Water Reactors.' pursuant to 10 CFR 50.54(f)."

GPU Nuclear responded to Generic Letter 90-06 in a letter dated December 24, 1990.

The NRC staff reviewed that response and in a letter dated October 29, 1992 provided comments regarding testing of the Power-0perated Relief Valve (PORV) anc' the incorporation of model Technical Specifications.

Because the application-of model Technical Specifications is a generic issue, the NRC comments affect the other B&W operating plants as well.

Therefore, the B&W Owners Group (BWOG) Technical Specifications Committee has undertaken an initiative to respond as an owners group. A telephone conference call involving the BWOG utilities and the NRC staff was held on December 17, 1992.

As a result of that discussion, a BW0G response addressing the model Technical Specification issue is being prepared with TMI-l participation.

GPU Nuclear has discussed a schedule for responding to the recent NRC comments.

with the THI-l NRC Senior Project Manager, Mr. R. W. Hernan.

GPU Nuclear understands that the NRC will consider an extension of the 60 day response 150074 9301150232 930111 a/4 PDR ADOCK 05000209 Ut t P
