B-1 APPENDIX B AREA WALK-BY CHECKLISTS (AWCS)

This appendix shows only the AWCs from the at-power seismic walkdowns performed the week of September 17, 2012 that were revised plus the AWCs resulting from the refueling outage seismic walkdowns performed on February 24, 2013. The AWCs from the at-power seismic walkdowns that are not shown herein can be found in Appendix B of Reference 34.

Location (Bldg, Elev, Room/Area): Area : AUX, 2047.5,1507 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)?

SGSO2B is flush with pyrocrete covering column to the East. Verification required to determine if essential vibration-sensitiveequipment is located within.

Licensing Basis Evaluation:

SGSO2B could not readily be determined to be without potentially adverse spatial interactionhazard. CR 66243 was generated by WCNOC to reconcile condition. Per CR #66243, a review of the panel determinedthat although the panel does contain relays that could potentially be vibration sensitive, the relays would only be requiredto function during post-accident sampling.

Momentary relay chatterduring a seismic event would not impact the ability of the analyzer to perform its design function or impactplant operation. The relays would not be permanently affected and work following the seismic event. No further action is required.

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

1. 66243, a review of the panel determined that although the panel does contain relays that could potentially be vibration sensitive, the relays would only be required to function during post-accident sampling. Momentary relay chatter during a seismic event would not impact the ability of the analyzer to perform its design function or impact plant operation. The relays would not be permanently affected and work following the seismic event. No further action is required.

Y - The Seismic Licensing Basis is satisfied and no adverse seismic condition exists.

N - As a result of the walkdown inspection, a corrective action was required.

G-3 Seismic Walkdown Equipment List, Rev. 1 Attachment to LTR-RAM-lI-12-083, Rev. 1 NTTF Recommendation 2.3: Seismic Walkdown Wolf Creek Generating Station Revision History Revision 0 of this document provides the Seismic Walkdown Equipment List (SWEL) developed prior to the Wolf Creek Generating Station (WCGS) At-Power Seismic Walkdowns, performed during the week of September 17, 2012. The SWEL contained a total of 117 components (112 in SWEL 1 and 5 in SWEL 2).

Revision 1 of this document revised the SWEL 1 table provided in Attachment 1 of this document to remove a component (XPN08B) associated with system type PN (Instrument AC Power). This component was removed because it was identified as being non safety related. The removal of XPN08B reduced the number of SWEL items from 117 to 116. It was not deemed necessary to replace XPN08B with a component of a similar class of equipment since the remaining equipment list still satisfied the Reference 1 guidance. XPN08B is a transformer and this component type, along with other attributes, remains adequately represented on the SWEL.

Seismic Walkdown Equipment List (SWEL)

A listing of structures, systems, and components (SSCs) that will be viewed during the walkdown, the SWEL, has been prepared in advance of the walkdown effort.

The selection of SSCs process described in EPRI Technical Report 1025286, Seismic Walkdown Guidance for Resolution of Fukushima Near-Term Task Force Recommendation 2.3: Seismic, dated June 2012 {Reference 1), was utilized to develop the SWEL for Wolf Creek.

The SWEL is comprised of two groups of items:

4- SWEL 1 (Attachment 1) is a sample of items to safely shut down the reactor and maintain containment integrity.

o. SWEL 2 (Attachment 2) is a list of spent fuel pool related items. Note that no rapid drain down items have been identified for Wolf Creek Generating Station, however, it is recommended that an area walk-by of the spent fuel building instrument air be conducted to ensure gate seal integrity.

Wolf Creek Operations and Engineering Staff Members participated in the selection of SSCs compiling the SWEL and provided direct input to the Equipment Selection Personnel during the SWEL development process. This input included:

• Confirmation of the equipment information retrieved from the Wolf Creek Seismic Category I documentation.

Wolf Creek Seismic Walkdown Equipment List March 6, 2013 Page 21 WCAP-17678-NP, Supplement 1 June 2013 Revision 1

G-4 Seismic Walkdown Equipment List, Rev. 1 Attachment to LTR-RAM-II-12-083, Rev. 1 NTTF Recommendation 2.3: Seismic Walkdown Wolf Creek Generating Station

" Discussions with the Equipment Selection Personnel to identify upgrades, modifications, and replacements of equipment which might be pertinent to the selection of the SWEL.

" Input into the selection of the SWEL using operational experience relevant to equipment classifications, safety function support, and environmental considerations.

• Approval of the components selected for the SWEL.

The process detailed in Reference 1 for the Selection of SSCs to produce the SWEL was discussed with the Wolf Creek Operations and Engineering Staff Members during the site visit August 2 7th through 2 8 nd, 2012. The details describing the process for Selection of SSCs to produce the SWEL will be provided in the "Selection of SSCs" section of the Submittal Report.

B.S. Chemical Engineering University of Puerto Rico, 1973 M.S. Nuclear Engineering University of Puerto Rico, 1975 Summary:

Rolando Perez is a Principal Engineer in the Risk Applications and Methods II Group of Westinghouse's Nuclear Services Division. Rolando has over 15 years of experience in Westinghouse and over 35 years of experience in the nuclear safety area.

From 1976 to 1977 Rolando worked for Westinghouse as a Training Engineer. Rolando supported the development of training programs for engineers and non-technical personnel of nuclear power plants.

Rolando conducted lectures on reactor core physics, health physics, fluid systems, protection systems, and plant operational concepts. Rolando was also involved in preparing and grading written examinations for Reactor Operator candidates.

From 1977 to 1979 Rolando worked for Westinghouse as a Transient Analyst. Rolando was responsible for performing the non-LOCA transient analyses for the nuclear plants designed by Westinghouse.

From 1979 to 1990 Rolando worked for Combustion Engineering (CE) as a Setpoint Analyst. Rolando was responsible for performing setpoint related calculations for the nuclear power plants designed by CE that employ analog-based reactor trip and monitoring systems (typically called the "CE analog plants").

Rolando was also involved in performing analyses associated with the setpoint process in the following areas: Core Physics and Thermal Hydraulics, Non-LOCA Transient Analysis, and Statistical Combination of Uncertainties.

In 1990 Combustion Engineering was acquired by Asea Brown Boveri (ABB). Rolando continued his role as a Setpoint Analysis under ABB until the year 1999.

In 1999 Westinghouse acquired ABB's nuclear division. Rolando continued his role as a Setpoint Analyst under Westinghouse. In the year 2009 Rolando expanded his expertise to include the CE-designed plants that employ digital-based reactor trip and monitoring systems (i.e., the plants that use the Core Protection Calculator System, CPCS, and the Core Operating Limits Supervisory System, COLSS; typically called the "CE digital plants").
