1. Valve SFP 719A outlet to SFP Demin Stop shows slight surface rust. As well as 2 pipe hangers on the pipe to this valve. Not significant.

2. Top of overhead concrete beam is jagged. Not a structural issue.3. Light bulb above 22SFP Pump is burnt out. This is not a seismic issue Lights Out Hotline (extension-7600) was contacted regarding the light out.4. Light safety cages on all three lights in the room appear to be sitting in the light fixtures incorrectly.

They look to be cross threaded.

Hard target pumps would not be rendered inoperable.

CR IP2-2012-06744 issued to track fixing the light safety cages.5. Multiple boric acid leaks noted in the area on SFP pumps. No significant boric acid corrosion observed.

Boric acid leaks are already work order tagged in the field for repairs. See photos below.

These partitions between EDG's have multiple cracked welds (see photos below). These partitions are discussed in CR IP2-2003-03195, and seismically qualified in calculation FCX-00534.

These partitions and calculation FCX-00534 require further investigation as cracked welds indicate a problem. CR 1P2-2012-06278 issued to track investigation and resolution of the cracked welds. Walk down team judged partitions to be seismically adequate with cracked welds.Walk down team recommends redesigning the partitions to include personnel loads (i.e. handrail lateral loads) as observations showed most personnel hold onto the ends of the partition when stepping next to the EDG's as the transition from flat grating to the sloped partition base is difficult.

Also recommend removing the sloped base as this makes walking next to the EDG's difficult and presents a safety issue.Comments (Additional pages may be added as necessary)

Grating south of 21 & 22 EDG's have their bearing bars spanning the wrong direction.

Bearing bars span east-west where they do not bear on structural floor beams. The bearing bars should be rotated 90 degrees to bear on structural steel as the grating is cupping underjust personnel load as the cross wires are beating all the weight. This is judged not to be a seismic issue but a safety issue. CR IP2-2012-06512 issued to track resolution.

It should be noted that this deficiency was previously noted in 1P2-2005-03784, IP2-2008-04346, and 1P2-2009-0195.

Oil is leaking onto the floor near 23 CCW Pump bed drain. CR IP2-2012-06615 issued to track resolution.

Conduit overhead to 23 CCW pump appears to be missing Appendix R fire proofing wrap in three places. Consultation with the Fire Protection Engineer determined that the intermittent insulation on the subject conduit is actually fire protection insulation for the support for another fire protected line.Therefore, there is no missing insulation.

Platform between 21RWST and Primary Water Storage Tank is very close to touching both tanks. Approximately 1/8" gap between tanks and platform.

LB-07 was performed to evaluate the gap.Roof cover on cabinet EPA-20 is close to RWST. Gap judged acceptable given components involved.Transmission tower is nearby & wihin fall arc of tank. Tower and tower anchorage judged acceptable seismically.

Transmission lines are over top of the tank are typically designed to withstand wind, snow, and ice loads.
