Proposed Changes to Technical Specifications fi Cooper Nuclear Station " ~%

1

" 1l NRC Docket No. 50-298, DPR-46 1

In accordance with the provisions specified in 10CFR50.90, Nebraska Public Power District requests that the Technical Specifications for Cooper Nuclear Station be revised to incorporate the following proposed change. It is further requested that this request for change be incorporated into the proposed changes dated January 30, 1980. Please note the similarity between Item 5 of the already outstanding proposal and the following.

Copies of the revised Technical Specification pages are enclosed with the change indicated.

1. Figures 3.11-1.3 and 3.11-1.4, page 211a:

Fuel exposure for Type 8D250 and Type 8D274 fuel at Cooper Nuclear Station is approaching the maximum exposure plotted on the Maximum Average Planar Linear Heat Generation Rate-(MAPLHGR) curves. Higher exposure points are being added which were generated using the approved methodology of NEDO-24045 " Loss-of-Coolant Accident Analysis Report for Cooper Nuclear Station . " NEDO-24045 was submitted September 1,1977, and was utilized in Amendment 39 to the Facility Operating License.

The safety significance of these proposed changes has been reviewed by appropriate District personnel, and under 10CFR170, these changes are judged to be a Class II amendment. However, g l- consistent with our request to incorporate this into an existing g proposed change, no payment is enclosed.
