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.

• Values to be determined l
