b. At least once per 31 days and once within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> after each solution volume increase of greater than or equal to 1% of tank volume by verifying the boron concentration of the safety injection tank solution. This fatter surveillance is not required when the volume increase makeup source is the RWT and the RWT has not been diluted since verifying that the RWT boron concentration is equal to or greater than the safety injection tank boron concentration limit.
c. At least once per 31 days when the RCS pressure is above 700 psia, by verifying that power to the isolation valve operator is disconnected by maintaining the breaker open by administrative controls.
d. At least once per 18 months by verifying that each safety injection tank isolation v matically under each of the following co Vc-~ot- +~ ~~ e.see.edi~
1. tual or simulated RCS pressure signalexeeede 515 psia, and
2. Upon receipt of a safety injection test signal.

V EHERGEHCY CORE COOLING SYSTEMS SURVEILLANCE RE UIREHENTS 4.5.2 Each ECCS subsystem shall be demonstrated OPERABLE:

a. At least once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> by verifying that the following valves are in the indicated positions with power to the valve operators removed:

0 Valve Number Valve. Function Valve Position

a. V3733 a. SIT Vent Valves a. Locked Closed V3734
b. V3735 b. SIT Vent Valves b. Locked Closed V3736
c. V3737 c. SIT Vent Valves c. Locked C1osed V3738 V3739 V3740
b. At least once per 31 days by verifying that each valve (manual, power operated or automatic) in the flow path that is not locked, sealed, or otherwise secured in position, is in its correct position.

C. By verifying that the ECCS piping is full of water by venting the accessible piping high points following maintenance, shutdown cooling system operation and/or any other activity which could cause the introduction of air into the system.

d. By a visual inspection which verifies that no loose debris gwags, trash, clothing, etc.) is present in the containment which could be transported to the containment sump and cause restriction of the puay suctions during LOCA conditions. This visual inspection shall be performed:
1. For all accessible areas of the containment prior to establishing CONTAIHHENT INTEGRITY, and
2. At least once daily of the areas affected within containment by the containment entry and during the final entry when CONTAINMENT INTEGRITY is establ ished.
e. At least once per 18 months by: ha.s+
1. Verifying automatic isolation and interloc action of the shutdown cooling system from the Reactor oolant System when RCS pressure (actual or simulated) is than or equal to 515 psia, and that the interlocks prevent opening the shutdown cooling system isolation valves when RCS pressure (actual or simulated) is greater than or equal to 276 psia.
