February 8,1980 Director, Nuclear Reactor Regulation Attention: Mr. Thomas A. Ippolito, Chief Operating Reactors Branch No. 3 Division of Operating Reactors U.S. Nuclear Regulatory Commission Washington, DC 20555

Subject:

Reload Licensing Submittal, Reload 5, Cycle 6 Cooper Nuclear Station NRC Docket No. 50-298, DPR-46

Dear Mr. Ippolito:

In accordance with the provisions of the Atomic Energy Act of 1954, and the amendments thereto, the Nebraska Public Power District requests that the operating license for Cooper Nuclear Station be revised to allow operation following the fifth refueling of the reactor.

Specifically, the results of the plant unique analysis are presented in the " Supplemental Reload Licensing Submittal for Cooper Nuclear Station Unit 1, Reload 5", NEDO-24230, dated December 1979, and are submitted as an enclosure to this letter. This document has been prepared utilizing the format contained in Appendix A of Ger.eral Electric Report NEDE-24011-P "BWR Generic Reload Fuel Application".

Proposed changes to the Cooper Nuclear Station Technical Specifications are enclosed with the changes as follows:

1. The Rod Block Monitor setpoint is being changed from 105% to 107% due to the results of the rod withdrawal error analysis.

2. The operating Minimum Critical Power Ration (MCPR) limits and Overpressurization Analysis results are revised .

3. Maximum Average Planar Linear Heat Generation Rate (MAPLHGR) curves are being added for type P8DRB265L and P8DRB283 fuel.

4. The requirement for the Safety / Relief Valve (SRV)

Bellows Monitoring System is only applicable to three stage SRV's. It is planned to replace all three stage SRV's with two stage valves.

The schedule for this refueling outage currently indicates that the station will be shutdown beginning March 15, 1980, for a period of approximately eight weeks; therefore, Nebraska Public Power District respectfully requests approval of this license amendment prior to May 1,1980. A brief summary of the station modifications planned for this outage is enclosed for your information.

The safety significance of these proposed changes has been reviewed by appropriate District personnel, and under 10CRF170, these changes are judged to be a Class III amendment. Payment in the amount of $4,000 is enclosed.
