- b. At least once per 31 days by verifying that the ECC5 picing is full of water by venting the E005 pump casings and discharge piping high points.
- c. By a visual inspection which verifies that no loose debris (rags, trash, clotning, etc.) is present in the containment which could be trans;crtec :: the containment emergency sump and cause restriction of the pump suction during LOCA con-ditions. This visual inspection snail be performed:
- 1. For all accessible areas of the containment prier to establishing CONTAINMENT INTEGRITY, and
- 2. Of the areas affected within containment at the completion of each centainment entry when CONTAINMENT INTEGRITY is es tabl ished.
- d. At least once per 18 months by:
- 1. See Attached Sheet
- 2. A visual inscection of the containment emergency sump which verifies that the subsystem suction inlets are not restricted by debris and tnat the sumo ecmoonents (trash racks, screens, etc.) show no evidence of structural distress or corrosion.
- 3. Verifying a total leak rate < 20 gallens per hcur for the 1 LPI systam at-a) Normal operating pressure er hyde static test oressure of 3,150 psig for those parts of tne system dcwnstream of the pump suction isolatien valve, and b) 3,45 psig for the piping frem the containment energency sump isolation valve to the pump suction isoltcion valve. -
