By a visual inspection which verifies that no loose debris (rags, c.
trash, clothing, etc.) is present in the containment which could be transported to the containment 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 each containment entry when containment integrity is established.
d.
At least once per 18 months by visual inspection of the containment sump and verifying that the subsystem suction inlets are not restricted by debris and that the sump components (trash racks, screens, etc.) show no evidence of structural distress or corrosion.
e.
At least once per 18 months, during shutdown, by:
1.
Cycling each power-operated valve in the flow path through at least one complete cycle of full travel.
2.
Verifying that valve CS-MOV-532 actuates to its correct position on a safety injection signal.
