SWEL Components: SWELl- 049, 050 Instructions for Completing Checklist This checklist may be used to document the results of the Area Walk-By near one or more SWEL items. The space below each of the following questions may be used to record the results of judgments and findings.

Additional space is provided at the end of this checklist for documenting other comments.

1. Does anchorage of equipment in the area appear to be free of YE N-- Ur- N/A[:]

potentially adverse seismic conditions (if visible without necessarily opening cabinets)?

The panel covering removable opening in masonry block wall 64.4 has a nut that is loose! not fully engaged. There's also a lose anchorbolt lying in the channel that mounts the braces to the floor. This is not a seismic concern as it's a robust design with redundantbolting.

2. Does anchorage of equipment in the area appear to be free of YE N[l UD- N/A[--

significant degraded conditions?

Mild surface oxidation noted on pump C-1 19 frame.

3. Based on a visual inspection from the floor, do the cable/conduit YZ NEI ur- N/AZ1 raceways and HVAC ducting appear to be free of potentially adverse seismic conditions (e.g., condition of supports is adequate and fill conditions of cable trays appear to be inside acceptable limits)?

If the room in which the SWEL item is located is very large (e.g., Turbine Hall), the area selected should be described. This selected area should be based on judgment, e.g., on the order of about 35 feet from the SWEL item.

4. Does it appear that the area is free of potentially adverse seismic Y[ NIj ULI N/AD spatial interactions with other equipment in the area (e.g., ceiling tiles and lighting)?

5. Does it appear that the area is free of potentially adverse seismic Y[ NEI U[D N/ADl interactions that could cause flooding or spray in the area?

A sprinklerhead is within two inches of the bottom of cable tray, but is adequately covered with a guard, therefore acceptable.

6. Does it appear that the area is free of potentially adverse seismic Y[ ND UD- N/AD interactions that could cause a fire in the area?

7. Does it appear that the area is free of potentially adverse seismic Y[ NDl uD N/ADl interactions associated with housekeeping practices, storage of portable equipment, and temporary installations (e.g., scaffolding, lead shielding)?

Scaffolding is currently being erected below the valves MO 1400-24B and MO1400-25B to allow access to them. This is a work in progress and is tagged appropriately. All extra equipment in the area is properly secured and cart wheels are choked.

1. Does anchorage of equipment in the area appear to be free of Y[O NE] uE- N/A-]

potentially adverse seismic conditions (if visible without necessarily opening cabinets)?

A fasteneris missing on the gaitronicscover next to instrument racks C2205A and C2205B. This is not a seismic hazard as the remaining three fasteners adequately secure the cover.

CR-PNP-2012-04657was written to address the missing fastener.

The cage! fence around the sample sink is missing a single set screw and what appears to be a mounting anchoron one of the posts. The mounting anchoris located in the walking path of the dooropening and therefore is a trip hazard, and so its exclusion was likely deliberate.

There are redundantfasteners the length of the fence and this is not a seismic concern and therefore is acceptable.

CR-PNP-2012-04659 was written to address the missing set screw.

A freestanding computer stand is appropriatelytagged for seismic missile hazard evaluation in the back panel area behind C-905; therefore, it is not considered a potentially adverse seismic interaction.

PrinterPNP669 is on a non-anchoredstand adjacent to C-220A, and the aspect ratio of the printerand stand is greaterthan 2:1. According to ENN-MS-S-009-PNP, Rev. 2, C-220A is non-safety related. This is the only piece of equipment the printercould potentiallyimpact, so this is not considered a potentially adverse seismic interaction. See photo "PNPS 10-16-12 TI 026" on Share Point.

PrintersLPO1, LP02, and LP03 are located on two stands bolted together. The aspect ratio of the entire assembly is less than 2:1 and it is located 66" from the nearestpanels. A computer cabinet adjacent to these printershas an aspect ratio of approx. 2:1, and is 118" from the nearestpanels. These do not present a seismic interactionconcern per Procedure 1.17.1, Rev. 12. See photos "PNPS10-16-12 T1 027" and "PNPS 10-16-12 TI 028" on Share Point.

A bookshelf is located between CP600 and a window frame, in contact with the panel and approx. 1" from the window frame. The bookshelf cannot fall forward due to the desk directly in front of the shelf; however, it could rattle into CP600. According to ENN-MS-S-009-PNP, Rev. 2, CP600is non-safety related,so this is not considereda potentially adverse seismic interaction. See photo "PNPS10-16-12 T1 029" on Share Point.

Long term scaffolding, logs 11-99, 11-56, and 11-99 are erected and approved for use in the room and do not present a potentially adverse seismic interaction.

Ladders located on the northwest wall were noted during the RP pre-job brief with the use of in-room, live cameras. These ladders could not be locally inspected due to dose concems. Therefore, the ladders could not be verified to be secured. However, based on the camera inspection, these ladders are not considered an adverse seismic interactionbecause the area is relatively free of equipment and the manner in which they are positioned will likely not lead to tipping into equipment.

The general housekeeping in the RWCU HX room on ReactorBuilding 51' is below standard. There are hoses, cords, tools, rope, and misc debris on the floor. None of the items were observed to present a seismic interactionhazard or have an immediate adverse impact on the equipment in the room. CR-PNP-2012-04739was written to address this item.

Two skewed anchorbolts, with threads not fully engaged were found on pipe support base plates to the east and west of SWEL 1-103. These were judged to be acceptable due to the small loads carriedby the supports and the short span length of the pipe, as well as the good condition of the base plate and support structure. These bolts were also evaluated duringprevious Wej-lt bolt inspections, indicated by the orange paint on the wall. See photos "PNPS 10-2-12 012" and "PNPS 10-2-12 016" in Share Point.

1. Does anchorage of equipment in the area appear to be free of YE NEi UI-- N/A[-]

potentially adverse seismic conditions (if visible without necessarily opening cabinets)?

An abandonedpipe support in the northwest cornerof the room has one partially disengagedanchorbolt. It is not supportingany load aside from self weight, and is judged to still be sufficiently attached to the wall. Therefore, it is not considereda seismic hazard. See photos "PNPS10-15-12 T1 032" to "PNPS 10-15-12 Ti 034" on Share Point.

Several Wej-lt anchors on the north wall are not fully engaged, but none have less than 75% engagement. Since the strength of Wej-lt anchors is not governed by full threadengagement of the nut, the state of these anchors is judged sufficient to develop the full design strength of the anchor. Therefore, it is not considered an adverse seismic condition. See photo "PNPS 10-15-12 TI 035" on Share Point.

Fluorescentlight fixture above the west side of the P208C cubicle is suspended by an open S-hook.

significant degraded conditions?

A base plate supporting drainpiping was noted to be missing anchor nuts and to be in poor condition. The support appears to have once supporteddrain line piping, but now only sits next to the piping. CR-PNP-04469 was written to address the item.

Evaluationby the Seismic Walkdown Engineers in accordance with EN-DC-168 concluded that this condition does not introduce an adverse seismic interaction. The very compact support assembly will remain in place during a seismic event due to the anchorstuds and two existing anchornuts. The drain piping is approximately 6 inches off the floor near the west wall, not in close proximity to any vulnerable components. Itis socket welded construction and otherwise well supportedsuch that displacements in a seismic event are expected to be less than 2 inches.

3. Based on a visual inspection from the floor, do the cable/conduit YE NEI U[-- N/AD--

raceways and HVAC ducting appear to be free of potentially adverse seismic conditions (e.g., condition of supports is adequate and fill conditions of cable trays appear to be inside acceptable limits)?

Vibration and testing wire is attached to pump 203A next to large bore piping and is touching the piping in a manner that could bend the wire in a seismic event. This is not a seismic concern as the wire is only used for maintenance and testing and would not affect any safe shutdown equipment.

'If the room in which the SWEL item is located is very large (e.g., Turbine Hall), the area selected should be described. This selected area should be based on judgment, e.g., on the order of about 35 feet from the SWEL item.

Loose thermal insulation was found on the floor of the room next to large bore piping and pump 215A. CR-PNP-04838 and WR 288901 were written to repairit.

The loose insulation representsan areaof approximately 2 -3 square feet as compared to hundreds of square feet of total piping insulation area. The loose insulationwill have no impact on accident conditions in the room.

Comments (Additional pages may be added as necessary)

A radworkerhat cover was found on top of piping above the valve, this is a housekeeping issue and was reported to operations. In addition, blue zip ties were loose and scatteredon the floor along the wall under valve 26-HO-33A. This is a generalplant housekeeping concern and not a seismic interactionhazard. It was reported to Operationsfor suggested removal (CR-PNP-2012-04472).

The set screw is stripped for TSD-45 & TSD-46. With strippedor missing set screws, the temperature switches are not restrainedvertically by the dogbone mounting sleeve.

The FSAR specifically states "Class II designated structures and/or equipment shall not degrade the integrity of any structures and/or equipment designated Class I". This is what is typically referred to as a potential seismic Il/I interaction. The blocks must be prevented from becoming missiles during a seismic event and adversely impacting safety-related (Class I) equipment in the area.

In addition to seismic loading, the shielding blocks must also be restrained when subjected to loads/pressures associated with postulated pipe breaks. FSAR Appendix C.2 lists the various breaks that have the potential to affect the bioshield wall blockouts, including the NI B nozzle location. The penetration blockout restraint steel was design for the maximum pressures resulting from a credible pipe break such that the shielding blocks will not become missiles during a pipe break transient and adversely impact safety-related equipment in the area.

Evaluation During the walkby it was observed that there were welded steel hooks to accommodate removable restraint steel for this blockout but the restraint steel was not in place. Review of plant documentation revealed that these blocks should have been removed during RFO15 (2005) when the restraint steel and all of the blocks in the upper portion of this penetration were removed per Plant Design Change ERCN 04114532 and Work Order WO51527937-01. Extensive searching of plant records found no documentation that authorized or justified leaving the unrestrained shielding blocks in the penetration opening.
