ATTACHMENT 1 Specification LCO 4.2.6 - Firewater Pumps, Limiting Conditions for Operation t

The engine driven fire pump, motor driven fire pump, and associated pump pits shall be operabic and there shall be at least 325 gallons of fuel in storage during power opera tion.

B_ asis for Specific *ation LCO 4.2.6 Rev. Either of the fire pumps operating in conjunction with either fire-water booster pump provides adequate capacity to operate a circulator water t

turbine and supply emergency cooling water for safe shutdown cooling. With the 325 gallons of fuel in storage, the engine driven fire pump can operate at rated conditions for 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> which is adequate time to have more fuel de-livered to the site. For further explanation see Final Safety Analysis Re-port, Sections 1.4,10.3, and 14.4.

Each firewater booster pump shall be tested annually by providing motive power to one water turbi..e drive in conjunction with the performance 1 of SR 5.2.7. In addition each pump shall be functionally tested quarterly.

The associated instruments and controls shall functionally be tested quarter-ly and calibrated annually.,.

Rev. Basis for Specification SR 5.2.22

. */ '

During accident conditions described in Final Safety Analysis Re-port, Section 14.4.2.1, one of the firewater booster pumps and one fireeater penp are required to provide adequate core cooling. The specified testing in-terval is sufficient to ensure proper operation of the pump and associated controls.
