LIMITING CONDITIONS FOR OPERATION 3.6.2.1 Two-separate and-independent containment quench .= pray subsystems shall be OPERABLE.

APPLICABILITY: MODES 1, 2, 3 and 4.

rACTION:

SURVEILLANCE REQUIRDiENTS 4.6.2.1 Each containment quench spray subsystem shall be demonstrated OPERABLE:

a. At least once per 31 days by:

1. Starting each spray pump.

• 2. Verifying, that on recirculation flow, when tested in accordance with the requirements of proposed Section 4.0.5, each quench spray pump develops a discharge pressure of 2; psig at a flow of > gpm and 3; psig at a flow of 2; gpm in the throttled mode.

3. Verifying that each spray pump operates for at least 15 minutes.

4. Cycling each testable power operated or automatic valve in

'

the flow path through at least one complete cycle of full travel.
