0 010 Northem States Power Company 414 Nicollet Mali Minneapohs Minnesota 55401 Telephone (612) 330-5500 November 7, 1983 Mr. James G. Keppler Regional Administrator - III U.S. Nuclear Regulatory Commission 799 Roosevelt Road Glen Ellyn, IL 60137

Dear Mr. Keppler:

PRAIRIE ISLAND NUCLEAR GENERATING PLANT Docket No. 50-282 License No. DPR-42 Docket No. 50-306 License No. DPR-60 In reviewing our commitments concerning IE Bulletin 83-03, it was found that one check valve which was to be tested at cold shutdown was not checked during the last Unit 2 refueling and maintenance shutdown period. The valve, 2CL-42-1 (Loop B Cooling Header Turbine Building Check Valve), was to be checked using the forward and back flow method during the outage. This will be placed in the plant'sSection XI program, along with other changes in the Section XI program dictated by NRC review of our initial program submittal and our second 10-year program submittal. In the process of making these changes, the Bulletin time requirement for testing 2CL-42-1 was overlooked. The test was scheduled the same as the other Section XI changes. Therefore, the teet was not done during the last Unit 2 refueling outage.

This test on 2CL-42-1 will be done the next time Unit 2 is at cold shutdown, or during the Unit I refueling outage (which begins next month) if combined cooling water flow is less than 10,000 gpm.

Sincerely, GEy C. E. Larson Director, Nuclear Generation cc: G. Charnoff C. Feierabend 03111702B1 031107 PDR ADOCK 05000 0
