2) Verifyf th valve (m.nual, rated, or automatic) in w path that is not locked, sealed, o ise secured in position, is in its correct position. N

c. By a visual inspection which veriffes that no loose debris (rags, 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.) show y debris 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.
