Subject:

Oyster Creek Nuclear Generating Station l' Docket No. 50-219 Technical ~ Specification Change Request No. 181 J

Pursuant to 10CFR50.90, CPU Nuclear Corporation, operator of the l Oyster Creek Nuclear Generating Station (OCNGS), Provisional Operating License No. DPR-16, requests a change to Appendix A of that license.

3 The attached Technical Specification Change Request proposes to eliminate eight (8) main steam safety valves with the two highest set' points. The original deoign for Oyster Creek Reactor Vessel was ASME Section I 1962 edition which was interpreted to require that the safety valve capacity be such that all potentially generated steam by the boiler (reactor vessel) be discharged without credit for-fuel stoppage. The ASME Section I deals specifically with power boilers ,j and not nuclear reactors. Recent codes and standards.(ASHE Section-I l and III) recognize operating controle or safety controls for the l protected system upon which the required relief capacity is l predicted. In addition, NUREG 0800, " Standard Review Plan" Section J 5.2.2.II.A allows credit for reactor scram for safety valve sizing.

Thus, the scram feature and' recirculation pump trip can be utilized in sizing relief capacity.

Based on the above, GPUN proposes that the high flux scram be used for determining the safety valve capacity, with the result being a ,

reduction in the number of-safety valves. This reduction will  ;

significantly reduce radiation exposure, probability of failures, i A

leakage and maintenance costs.

We request the NRC. staff.to place an appropriate priority for a timely review of these proposed Technical Specification changes, such that the modification can be scheduled and completed during the 13R outage.

This change request has been reviewed in accordance with Section 6.5 of the OCNGS Technical Specifications, and using the standards in 10 CFR 50.92 we have concluded that-these proposed changes do not

-constitute a significant hazards consideration..

Pursuant to 10CFR50.91(b)(1), a copy of this change request has been sent to the State of New Jersey Department of Environmental Protection.

Very truly yours, 1
