Re: Oconee Nuclear Station c) iD Docket Nos. 50-269, -270, -287

Dear Sir:

Your letter dated December 18, 1975 indicated various changes to model Technical Specificaricns relating to hydraulic shock suppressors which had previously been transmitted by your letter dated June 30, 1975.

These changes resulted from review of our August 15, 1975 submittal as well as consideration of other licensee submittals and your own further review of the subject.

Pursuant to 10 CFR 50.90, please find attached a proposed amendment to the Technical Specifications for the Oconee Nuclear Station which is in basic agreement with the revised model specifications which you supplied concerning hydraulic shock suppressors. The provision for monthly testing of shock suppressors whose seal material is not compatible with the operating environment has not been included since all Oconee shock suppressors have been determined to be compatible with tae operating environment. The provision for functional testing of the suppressors has not been included in our proposal. Functional testing of suppressors is performed at the vendor's factory to verify proper design, fabrication, and operation. The visual inspection of the suppressor is intended to  !

verify continued operability of the suppressors. It is also considered l that due to the internal design of the suppressors, it is extremely unlikely that a failure could occur. Oconee has not experienced a failure of a I suppressor due to internal failure. In addition, suppressors which require maintenance which could affect a ressor operation will be functionally

. e ,,

Table 4.18-1 indicates those safety related shock suppressors .-hich are to be considered by this Technical Specification. All suppressors in the Reactor Buildings have been classified as inaccessible during normal operation due to the radiation level and temperature considerations.

Suppressor surveillance will continue as presently required in Oconee Technical Specification 4.1 until such time that this request for amendment of the Facility Operating License is approved. Suppressor surveillance subsequent to approval cf this amendment will be performed within six months of the date of issuance of these technical specifications or within the previous surveillance frequency, whichever is sooner.

Ve truly yours, av' $.
