Valve Number- Valve Function Valve Position '

a. 2SI-V1556 a. Hot Leg Injection a. SHUT

($1-506A)

b. 2SI-V1557 b. Hot Leg Injection b.

d. SHUT (51-5068) i 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 a visual inspection which verifies that no loose debris (rags, trash, clothing, etc.) is present in the containment which could be -j transported to the safety injection system sump and cause restriction of the pump suctions during LOCA conditions. This visual inspection shall be performed:

1.

For all accessible areas of the containment prior to '

establishing CONTAINMENT INTEGRITY, and 2.

Of the areas affected within containment at the completion.of containment entry when CONTAINMENT INTEGRITY is established.

d. At,least once per 18 months by:

1.

Verifying automatic isolation and interlock action of the '

shutdown cooling system from the keactor Cocient System when the Reactor 700 Coolant Systere pressure (actual or siculeted) is 1 20 psia.
