N By a visual inspection which veriffes that no loose debris (rags, c.

trash, clothing, etc.) is present in the containment which could be transported to the Containment Emergency 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 estabitsh-ing CONTAINMENT INTEGRITY, and 2)

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

At least once per 18 months by:

1)

Verifying automatic isolation ac4cn of the RHR system from the l

Reactor Coolant System by ensuring that with a simulated or actual Reactor Coolant System pressure signal greater than or equal to 365 psig the interlocks prevent the valves from being l-opened.

l 2)

A visual inspection of the Containment-Emergency Sump and verify-l ing that the subsystem suction inlets are not restricted b and that the sump components (trash racks, screens, etc.) y debris show no evidence of structural distress or abnormal corrosion.

• Either valve may be realigned in Mode 3 for testing pursuant to Specification 4.4.6.2.2.
