20555 Attn:

A. B. Davis

Dear Mr. Davis:

This is to confirm a verbal report made to Mr. R. Kazmar of your staff at 0929 hours0.0108 days <br />0.258 hours <br />0.00154 weeks <br />3.534845e-4 months <br /> on May 25, 1988.

At that time, Mr.

Kazmar was informed that at 1444 hours0.0167 days <br />0.401 hours <br />0.00239 weeks <br />5.49442e-4 months <br /> on May 24I 1988, a

test had been conducted on the Fire Suppression Water System (FSWS) which required placing the FSWS in a less conservative configuration than that required by Technical Specification 3.7,9.1 for both Units 1 and. 2.

The test conditions required the electric motor driven fire pumps to be tagged out and the Diesel Fire Pumps to be placed under>

manual operator control to allow for testing of the Fire Pump Logic System.

The FSWS was restored to the Technical Specification requirements in approximately five minutes.

This impairment was implemented under an approved test procedure as a preplanned evolution.

In preparing for the impairment, the two 2,000 gallon per minute electric motor driven fire pumps were removed from service under the Plant Clearance Permit System.

Immediately prior to the test, at 1444 hours0.0167 days <br />0.401 hours <br />0.00239 weeks <br />5.49442e-4 months <br />, each unit's Control Room manually locked out the start logic for their respective 2,000 gallon per minute diesel engine driven fire pump.

At all times during the

test, Control Room personnel were available to return the diesel fire pumps to service in the event of a fire alarm or other form of notification of a fire emergency.

Both diesel fire pumps were returned to service at 1449 hours0.0168 days <br />0.403 hours <br />0.0024 weeks <br />5.513445e-4 months <br /> on May 24, 1988, bringing the FSWS into compliance with Technical Specification 3.7.9.1 for both units.

The electric motor driven fire pumps were returned to service at 1630 hours0.0189 days <br />0.453 hours <br />0.0027 weeks <br />6.20215e-4 months <br /> on May 24, 1988.

The requirements of Technical Specification 3.7.9.1, Action b.l were complied with in that procedural arrangements were made to immediately restore Fire Suppression System capability in case of a fire emergency.
