Dear Mr. Grier:

In accordance with Appendix Specifications 3.7.14.1 and 6.9.2, Fire Suppression Water System, the following occurrence is reported. This ~

occurrence was reported to Mr. J. D. Hegner, the Beaver Valley Unit 1 NRC Resident Inspector, at 1420 hours0.0164 days <br />0.394 hours <br />0.00235 weeks <br />5.4031e-4 months <br /> on May 19, 1980.

Plant operators sere testing the diesel-driven fire pump on Monday, May 19, 1980 when they received a high temperature alarm. During that morning, the fire pump was started three times due to fire system testing; each time.

the pump was subsequently shutdown. The first time the pump was run was for the weekly diesel-driven fire pump surve11'ance test from 0816 until 0846 hours0.00979 days <br />0.235 hours <br />0.0014 weeks <br />3.21903e-4 months <br />. The second pump run was a result of a low system pressure auto-start while doing the fire system alarm test, which was from 0858 until 1044 hours0.0121 days <br />0.29 hours <br />0.00173 weeks <br />3.97242e-4 months <br />. The third start was the result of low system pressure, again due to testing. The pump was running the third time from 1116 until 1208 hours0.014 days <br />0.336 hours <br />0.002 weeks <br />4.59644e-4 months <br /> when it was idled down and then shutdown due to a high temperature alarm. An investigation is underway at this time.

The plant motor-driven fire pump is presently out of service; however, a temporary fire pump is hooked up for service and it is felt that degradation to the system is minimized because of this backup pump.

Very truly yours, -

f y 1-J. A. Werling
