b.
At least once per 31 days by:
)
1)
Verifying that the ECCS piping is full of water by venting the ECCS pump casings and accessible distnarge piping high points, and 2)
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 a visual inspection which verifies that no loose debris (rags, trash, clothing, etc.) is present in the containment which could be transported to the containment wmo and cause restriction of the pump suctions during LOCA conuttions.
This visual inspection shall be performed:
1)
For all accessible areas of the containment prior to establisn-ing CONTAINMENT INTEGRITY, and 2)
Of the areas affected within containment at the completion of each containment entry when CONTAINMENT INTEGRITY is establishe:
d.
At least once per 18 months by:
1)
Verifying automatic #::12ti r and interlock action of the resicual heat removal system f rom the Reactor Coolant System by ensuring that/f et w eith a simulated or actual Reactor Coolant System pressure signal greater than or ecual to 425 psig the interlocks
)
prevent the valves from being opened, efte-1%%d uc.

1)
Verifying that each automatic valve in the flow path actuates to its correct position on Safety Injection and Containment Sump Recirculation test signals, and 2)
Verifying that each of the following pumps start automatically upon receipt of a Safety Injection test signal:
a)
Centrifugal charging pump, b)
Safety Injection pump, and c)
Residual heat removal pump.

By verifying that each of the following pumps develops the indicated differential pressure when tested pursuant to Specification 4.0.5:
1)
Centrifugal charging pump 1 2223 psid, 2)
Safety Injection pump 2 1341 psid, and 3)
Residual heat removal pump 1 165 psid.
