B-185 Status: YEE U Area Walk-By Checklist (AWC)

Location (Bldg, Elev, Room/Area): Area : CTRL, 2047.5, 3601 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 potentially Yes adverse seismic conditions (if visible without necessarily opening cabinets)?
2. Does anchorage of equipment in the area appear to be free of significant Yes degraded conditions?
3. Based on a visual inspection from the floor, do the cable/conduit raceways and Yes 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)?

4. Does it appear that the area is free of potentially adverse seismic spatial Yes interactions with other equipment in the area (e.g., ceiling tiles and lighting)?

SWT cannot verify whether SP-010 and KC-C08 are securely fastened so as to preclude chatter. WCNOC Operationsconfirmed that both cabinets are NNS; therefore chatter does not pose adverse seismic concern.

5. Does it appear that the area is free of potentially adverse seismic interactions Yes that could cause flooding or spray in the area?
6. Does it appear that the area is free of potentially adverse seismic interactions Yes that could cause a fire in the area?
7. Does it appear that the area is free of potentially adverse seismic interactions No associated with housekeeping practices, storage of portable equipment, and WCAP-17678-NP November 2012 Revision 0

Observed portabletable approx. 3/4" from control panel. Table could rock and impact the panel. Shift managerindicatedthat Engineeringqualified the table for SSE. Verify whether the table has seismic calculationjustifying placement where it was located or remove to a safe location.

Licensing Basis Evaluation: No qualification document was identified to justify presence of table in proximity to safety-related control panel equipment. CR 57419 was issued by WCNOC documenting removal of table to safe location.

8. Have you looked for and found no other seismic conditions that could Yes adversely affect the safety functions of the equipment in the area?

Location (Bldg, Elev, Room/Area): Area : CTRL, 2047.5, 3605 temporary installations (e.g., scaffolding, lead shielding)?

1.) Trash can againstRL021 can impact safety-relatedsensitive equipment.

Moved on spot by Operationsto safe position. CR 57422 issued by WCNOC documenting removal of trash can to safe location.

2.) In SE corner, the SWT observed a rolling step ladderthat was not clamped and could impact non nuclear safety (NNS) cabinets.

Since the items were NNS, there was no adverse condition, but better housekeeping practice is recommended. Similar concerns were noted for exercise equipment adjacent to NNS cabinets.

3.) In NE corner, the area is used as storage. Since there is no safety-related equipment in proximity, there is no adverse condition. However, better housekeeping practice is recommended.

4.) South of RK045C3 & RK045C4, noted two rolling test racks with wheels clamped in posted storage area. The concern is that the cabinets could overturn and impacts cabinets. Operation verified RK cabinets.as NNS; therefore no adverse seismic concern.

8. Have you looked for and found no other seismic conditions that could Yes adversely affect the safety functions of the equipment in the area?

General note for equipment w/ modified top fasteners added to rigidly connect tops of cabinets. Verify whether modifications reconciled individual equipment qualifications.

Licensing Basis Evaluation:Bolted connections of cabinets in control room area is analyzed per WCNOC CalculationXX-FH-009-002. No adverse seismic concern.

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 potentially Yes adverse seismic conditions (if visible without necessarily opening cabinets)?
2. Does anchorage of equipment in the area appear to be free of significant Yes degraded conditions?
3. Based on a visual inspection from the floor, do the cable/conduit raceways and Yes 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)?

Overheadcable tray, conduit, and HVAC are ruggedly supported and poses no seismic hazard to equipment below. No concern.

4. Does it appear that the area is free of potentially adverse seismic spatial Yes interactions with other equipment in the area (e.g., ceiling tiles and lighting)?

1.) SWT noted fire piping is flexibly supported(rod-hung) with Victaulic couplings. Verify whether 2:1 adequacy from qualificationdocuments. 2.)

Noted lighting supportedby its own conduit spanning horizontally. Concern is that flexibly support light could overstress conduit and fall. Verify whether lighting supportis adequate.

Licensing Basis Evaluation: 1.) Per WCNOC Specification M-650, fire piping in diesel generatorbuilding is designed for Seismic Category 2:1 qualifications; therefore no adverse seismic condition. 2.) Re-inspection of photos shows conduit is galvanized rigid conduit, which has significant bending capacity to resist vertical loading of light. No adverse seismic concern.

5. Does it appear that the area is free of potentially adverse seismic interactions Yes that could cause flooding or spray in the area?

Noted rod-hung fire piping with Victaulic coupling. Electrical components have drip shields and fire piping verified as pre-activatedper fire suppression drawings. Therefore no spray hazard.

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

Noted rolling step laddernot tied off and wheels not locked. No safety-related equipment is within the zone of influence of the ladder; therefore no hazard.

Ops removed ladder. The SWT also noted a slender storage cabinet that is unanchored,. The concern is that the cabinet could overturn; however no soft targets are located within the zone of influence. Therefore there is no adverse concern but SWT recommended to positively anchor the cabinet to the floor as a good practice.

8. Have you looked for and found no other seismic conditions that could Yes adversely affect the safety functions of the equipment in the area?

1. Does anchorage of equipment in the area appear to be free of potentially Yes adverse seismic conditions (if visible without necessarily opening cabinets)?
2. Does anchorage of equipment in the area appear to be free of significant Yes degraded conditions?

Noted surface corrosion throughout area due to harsh environment. No indicationof strength loss and therefore no adverse seismic concern, but noted to site to be vigilant of future corrosion.

3. Based on a visual inspection from the floor, do the cable/conduit raceways and Yes 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)?

4. Does it appear that the area is free of potentially adverse seismic spatial Yes 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 interactions Yes that could cause flooding or spray in the area?

No fire protection in area and process waterpiping is well-supported. In addition, area has sufficient drainagecapacity and sensitive equipment is elevated. Therefore, there is no flooding/sprayhazard.

SWT noted an unanchored waste can (typical of plant) with no safety-related equipment within zone of influence. No hazard.

Approximately 30' tall scaffold heavily braced back to wall at frequent intervals and therefore poses no seismic hazard to equipment.

8. Have you looked for and found no other seismic conditions that could Yes adversely affect the safety functions of the equipment in the area?

Significant surface corrosionon flange bolts for valve downstream of strains.

Ops indicatedthat bolts newly installed. No indication of area loss indicative of strength degradation;therefore no adverse seismic concern.
