The items will be walked down during a unit outage or time when the equipment is accessible, as appropriate.

Table E-1 summarizes the reasons each item is inaccessible during normal plant operation and notes the Braidwood Station Issue Report (IR) that has been written to track completion of the Seismic Walkdowns (and Area Walk-bys) for these items. It is noted that SSCs identified on Table E-1 require a complete inspection including, as applicable, internal inspections of electrical cabinets for other adverse seismic conditions, as required.Certain cabinets require supplemental internal inspection for other adverse seismic conditions as summarized in Table E-2. Supplemental internal inspections of these cabinets are required due to clarifications provided by the NRC after the online seismic walkdowns were completed.

These Supplemental inspections will be completed during a unit outage or another time when the equipment is accessible, as appropriate.

It is noted, that SSCs identified on Table E-1 do not appear on Table E-2.E-1 Braidwood Station Unit 2 12Q0108.1O-R-002 Rev. 0 Correspondence No.: RS-12-159 Table E-1.

Mr. Ram is an advanced degree nuclear engineer with over 25 years of nuclear power plant experience.

1.3 SWEL DEVELOPMENT The SWEL development was performed by Mr. Kim L. Hull of S&A. The peer review of the SWEL development was concurrent with the SWEL development.

The completed SWEL Peer Review Checklist is found in Attachment

2. The discussion for the SWEL development peer review is found in Section 2.Sheet 2 ,of 12 F-3 Braidwood Station Unit 2 12Q0108.10-R-002 Rev. 0 Correspondence No.: RS-12-159 1.4 SEISMIC WALKDOWN INSPECTION The peer review of the seismic walkdown inspection started on August 30, 2012 with a peer check of the actual walkdowns for Unit 2. Mr. Bacon joined the walkdown team for a portion of the day's planned walkdowns to observe the conduct of walkdowns and adherence to the Seismic Walkdown Guidance (SWG)l. No additional peer review site visits were made for the Unit 2 walkdown as the same procedures were implemented and nearly the same SWEL equipment was inspected.

However, an interview was conducted by Messrs. Djordjevic and Lory with the SWE inspection team on September 29, 2012 after review of a sample of the Unit 2 Seismic Walkdown Checklists (SWC) and Area Walk-By Checklists (AWC) to ascertain the quality and procedural compliance with the SWG. The discussion of the sample SWC and AWC is provided in Section 3.1.5 Conclusion of Peer Review -Selection of SSCs This peer review concludes that the process for selecting SSCs to be included on the seismic walkdown equipment list appropriately followed the process outlined in reference 1, Section 3: Selection of SSCs. It is further concluded that the SWEL sufficiently represents a broad population of plant Seismic Category 1 equipment and systems to meet the objectives of the NRC 50.54(f) Letter.1 Seismic Walkdown Guidance For Resolution of Fukushima Near-Term Task Force Recommendation 2.3: Seismic, EPRI Report 1025286, June 2012.Sheet 3 of 12 F-4 Braidwood Station Unit 2 12Q0108.10-R-002 Rev. 0 Correspondence No.: RS-12-159 2Peer Review -Selection of SSCs 2.1 PURPOSE The purpose of this section is to describe the process that was used to perform the peer review of the selected structures, systems, and components, (SSCs) that were included in the Seismic Walkdown Equipment List (SWEL).This section documents the Peer Review -Selection of SSCs performed for Braidwood Unit 2 2.2 PEER REVIEW ACTIVITY -SELECTION OF SSCs 2.2.1 Peer Review Activity -Selection of SSCs The guidance 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}, Section 3: Selection of SSCs was used as the basis for this review.This peer review was based on reviews of the following documents:

1) UFSAR chapters 3, 6, 7, 8 and 9 2) SWEL 1 & SWEL 2 3) P&ID M-63: Fuel Pool Cooling and Clean-Up This peer review was based on interviews with the following individual(s) who was (were) directly responsible for development of the SWEL: Kim Hull This peer review utilized the checklist shown in Reference 1 Appendix F:-Checklist for Peer Review of SSC Selection.

For SWEL 1 development, the following actions were completed in the peer review process:* Verification that the SSCs selected represented a diverse sample of the equipment required to perform the following five safety functions:

o Reactor Reactivity Control (RRC)o Reactor Coolant Pressure Control (RCPC)o Reactor Coolant Inventory Control (RCIC)o Decay Heat Removal (DHR)Sheet 4 of 12 F-5 Braidwood Station Unit 2 12Q0108.1O-R-002 Rev. 0 Correspondence No.: RS-12-159 o Containment Function (CF)This peer review determined that the SSCs selected for the seismic walkdowns represent a diverse sample of equipment required to perform the five safety functions.

This conclusion was based on a review of UFSAR chapters 3, 6, 7, 8 and 9 and SWEL 1 which determined that all five safety functions (RRC, RCPC, RCIC, DHR, and CF) are adequately represented.

Verification that the SSCs selected include an appropriate representation of items having the following sample selection attributes:

o Various types of systems o Major new and replacement equipment o Various types of equipment o Various environments o Equipment enhanced based on the findings of the IPEEE o Risk insight consideration This peer review determined that the SSCs selected for the seismic walkdowns include a sample of items that represent each attribute/consideration identified above. The justification for this conclusion is: a) Based on a review of UFSAR chapters referenced above and SWEL 1 list, it was determined that appropriate variety of equipment and systems are represented (e.g., EDG, Component Cooling, Aux Feed, Charging, Essential Service WTR, RHR, Batteries, Battery Chargers, Low and Med Vol Switchgear and MCCs); b) The "New or Replace" equipment are indicated as such; c) A variety of location environments are included:

e.g., MCCs (Auxiliary

@ EL: 346, 383, and 426), Pumps (Auxiliary

@ EL: 330, 364, and 383), Tanks and Heat Exchangers (Auxiliary and Containment), and Valves (Auxiliary and Containment);

d) The IPEEE Enhancement related equipment is indicated as such; and e) The risk quantification has been included in the "Comments" column.Note: Because of accessibility reasons, some equipment has appropriately been deferred to Outage.For SWEL 2 development, the following actions were completed in the peer review process:* Verification that SFP related items were considered and appropriately added to SWEL 2.This peer review determined that spent fuel pool cooling system Seismic CAT 1 items were given appropriate consideration and included on the list. This determination is based on a review SWEL 2 list, FSAR chapters 3 and 9, and FP Cooling and Clean-Up System P&ID M-63.* Verification that appropriate justification was documented for spent fuel pool related items that were not added to the SWEL 2.This peer review determined that an appropriate level of justification was documented for those items related to the spent fuel pool that were not added to SWEL 2. The justification for not including any Seismic Category I Structure has appropriately been documented in the interim report. There are no rapid drain down related components in SWEL2. Appropriate justification for this item is included in the interim report as well.Sheet 5 of 12 F-6 Braidwood Station Unit 2 12Q0108.1O-R-002 Rev. 0 Correspondence No.: RS-12-159 2.2.2 Peer Review Findings -Selection of SSCs This peer review found that the process for selecting SSCs that were added to the SWEL was consistent with the process outlined in Reference 1 Section 3: Selection of SSCs.The peer review checklist is attached to this document.This peer review resulted in no additional findings.2.2.3 Resolution of Peer Review Comments -Selection of SSCs All comments requiring resolution were incorporated prior to completion of this peer review.2.2.4 Conclusion of Peer Review -Selection of SSCs This peer review concludes that the process for selecting SSCs to be included on the seismic walkdown equipment list appropriately followed the process outlined in Reference 1, Section 3: Selection of SSCs.

The scaffolding and seismic housekeeping procedures was reviewed by the SWEs in order to gain a full understanding of the plant practices in regard to those procedures.

There were concerns noted in Unit 2 with regard to scaffold erection.With regard to seismic housekeeping, there were numerous instances cabinets being placed in unapproved locations.

Braidwood procedure BwAP 1100-23 -"Seismic Housekeeping Requirements for the Temporary Storage of Materials in Category 1 Areas" was reviewed and IRs created to provide the appropriate disposition.

Generally, if they were found to not to contribute to a credible seismic interaction they were adjudged acceptable and not dispositioned to an IR. Similarly, if an item posed a potential proximity hazard to a vital component and it was removed "on the spot" in accordance with the housekeeping procedure then it was also not dispositioned to an IR.However, in all instances the Seismic Walkdown Checklist (SWC) document the details of the occurrence, the action taken (if any) and the conclusion rendered by the SWE inspectors.

Importantly, if the situation warranted a correction then an IR was specifically generated for that component or area in the case of area walk-bys.Sheet 8 of 12 F-9 Braidwood Station Unit 2 12Q0108.1O-R-002 Rev. 0 Correspondence No.: RS-12-159 It is recommended that when maintenance activities are undertaken that attention be given with regard to storage of temporary equipment/cabinets.
