\P)'s

Dear Sir:

Pursuant to 10 CFR 50, 5 50.90, please find attached a proposed amendment to the Oconee Nuclear Station Facility Operating License and revision to the Technical Specifications. This proposed change extends the Oconec Unit 2, Cycle 5 operating ler gth to 390 EFPD.

Oconee Technical Specification 3.5.2.9 requires that an evaluation be performed to verify that operationa) limit curves are valid for operation beyvnd the nominal design cycle length. This evaluation has been performed and has confirmed that the existing Oconee 2 operating limit Technical Specifications are valid. The current Oconee 2 Technical Specifications state that the operational limits are valid to 360 I 10 EFPD. This pro-posal revised the title block of each affected Specification to state that the limits are valid to 390 + 10, - 30 EFPD. As a consequence, the Cycle 6 length of Oconee 2 will have a nominal design length somewhat shorter than previously planned (N400 EFPD).

With the current burnup of Oconee 2, Cycle 5, the current Technical Specifi-cation will expire September 12, 1981, assuming a 100 percent capacity factor for the Unit. The prcposed extension would allow continued opera-tion of Unit 2 until its scheduled refueling shutdown in early October.

In order to allow continued operation of Unit 2 beyond the above date, prompt approval by the Staff is requecced.

Pursuant to 10 CFR 170, S 170.22, this amendment request is deemed to consist of one Class II license fee, in that the evaluation has been per-formed by Babcock & Wilcox, the Oconee NSSS vendor, on behalf of Duke Power Company and it is an administrative matter to revise the affected Technical Specifications. As such, please find a el ek in the amount of $1,200.

ry truly yours,

\
