• RR,19-171 D-24 kw(ý -U 2ý -1%AWC for 239' Elevation 426 and 427 DC Battery Rooms Issue: Per EPRI 1019199, "Experience-Based Seismic Verification Guidelines for Piping and Tubing: Volume I-Seismic Verification Procedure, and Volume II -Performance of Piping and Tubing in Strong-Motion Earthquakes," Section 3.2.6, Victaulic couplings used in piping systems should be evaluated to determine if they will "partially or fully separate" during a seismic event. During walkdowns in the Limerick Unit 2 DC Battery Rooms 426 and 427, it was Identified that fire protection lines installed per ECR 99-00484 Include Victaulic couplings.

If these couplings leaked during a seismic event, spray might impact the operability of the safety-related Division 1 and Division 2 batteries.

Disposition:

The 3-inch fire protection line routed through Rooms 426 and 427 is directly over the safety related Division 1 and Division 2 batteries.

A conservative estimate of the piping rotation due to seismic loading at the Victaulic coupling will be determined and compared with the manufacturer's maximum permissible rotation to determine if the coupling will leak/spray during a seismic event.The fire protection line penetrates the rooms' reinforced masonry block walls via core bores. The grouted-in core bore penetrations provide lateral support during a seismic event. The line also includes two rod hangers (H07 and H07A) in each room which provide support in the vertical direction.

The Victaulic couplings are just inside of the core bores on each side of the room (less than 1 ft per Dwg.M-049-276).

The piping is considered to be rigid at the grouted core bores. Since the couplings are so close to the rigid wall connections and they act similar to hinged connections, the piping in each room can be considered to be simply supported between the two Victaulic couplings.

The maximum rotation at the Victaulic coupling is estimated below. The worst case loading will be lateral because the vertical direction has additional supports (H07 and H07A). The lateral seismic loading of 1.7g is taken from the support evaluation in ECR 99-00484, and Is increased by 20% to account for two pipe fittings and a small pipe jog. The maximum expected rotation due to seismic loading is estimated to be about 0.50. Per Victaulic Catalog 06.04, a 3-inch Series 77 coupling can accommodate up to 1.00. Therefore, the Victaulic couplings in the fire protection lines above the batteries in Rooms 426 and 427 are acceptable in this application.

Therefore, the Victaulic couplings In the fire protection lines above the batteries in Rooms 426 and 427 are acceptable in this application.

2.3 Seismic

Walkdowns performed by MPR Associates, Inc.for Unit 2 of Limerick Station. The peer review addresses the following activities: " Review of the selection of the structures, systems, and components, (SSCs)that are included in the Seismic Walkdown Equipment List (SWEL),* Review of a sample of the checklists prepared for the Seismic Walkdowns

&Walk-Bys,* Review of any licensing basis evaluations," Review of the decisions for entering the potentially adverse conditions in to the plant's Corrective Action Program (CAP), and* Review of the final submittal report.F.1.2 PEER REVIEWERS The Peer Reviewers are Patrick Butler, Caroline Schlaseman and Craig Swanner. Mr.Butler is the Peer Review Team Leader, per the EPRI Seismic Walkdown Guidance (Reference 1). As Peer Review Team Leader, he was responsible for the entire peer review process, including completion of the final peer review documentation in this report. The Peer Reviewers' qualifications are briefly summarized as follows:* Mr. Butler is a degreed mechanical engineer and has over twenty-five years of nuclear power experience.

Mr. Butler and has been trained as a Seismic Capability Engineer (EPRI SQUG training) and is the primary author of EPRI SQUG Guidelines for the use of the SQUG Generic Implementation Procedure (GIP) for new and replacement components and equipment.

• Ms. Schlaseman is a degreed civil/structural engineer and has over 30 years of nuclear power experience.

Ms. Schlaseman and has been trained as a Seismic Capability Engineer and EPRI Seismic Walkdown Engineer (SWE), has performed USI A-46 (SQUG) seismic walkdowns for two stations, and is a principal investigator in (EPRI) document 1025286, "Seismic Walkdown Guidance:

Mr. Swanner has been trained as a Seismic Capability Engineer and EPRI Seismic Walkdown Engineer (SWE).Limerick Generating Station Unit 2 F-4 MPR-3801, Revision 1 Correspondence No.: RS-12-171 Mr. Butler, Ms. Schlaseman and Mr. Swanner are registered professional engineers.

F.1.3 SWEL DEVELOPMENT The SWEL development was performed by Mr. Tom King. The initial peer review of the SWEL development was performed by Mr. Butler and Mr. Swanner, and was conducted between July 18, 2012 and August 8, 2012. There were two observations noted on the SWEL Peer Review Checklist but no findings were cited. The completed SWEL Peer Review Checklist is found in Attachment 1 to this Appendix.

The discussion for the SWEL development peer review is provided in Section F.2. Note that due to equipment accessibility including ALARA and electrical safety concerns, changes to the SWEL were made as the walkdowns were conducted.

The Peer Review Team did review changes made during the walkdown and has reviewed the final SWEL included in Appendix C of the Walkdown Report. As noted in the SWEL Peer Review Checklist, there were no items from IPEEE equipment class 11, Motor-Generators.

This was because there are no safety-related Seismic Category I motor generators at Limerick Unit 2. Also, the SWEL only includes 3 items of new or replacement equipment.

The low number of new equipment on the SWEL is because Limerick Unit 2 has not made significant changes to Seismic Category I equipment.

F.1.4 SEISMIC WALKDOWN The peer review of the seismic walkdowns was performed by Mr. Butler and Ms.Schlaseman on-site and during follow-up reviews. The review included approximately 25% of the total SWC or AWC applicable to the equipment including checklists, photos, and drawings where applicable.

Interviews were conducted with both teams of SWEs to assess conduct of the walkdowns and adherence to the EPRI Seismic Walkdown Guidance (Reference 1). The discussion of the review of the sample of Seismic Walkdown Checklists (SWCs) and Area Walk-By Checklists (AWCs) is provided in Section F.3.The assessment of condition reports (IRs) with respect to current licensing basis is provided in Section F.4. These assessments and their outcomes were also discussed with the SWE inspection team in order to completely understand the issues.Limerick Generating Station Unit 2 F-5 MPR-3801, Revision 1 Correspondence No.: RS-12-171 F.2 Peer Review -Selection of SSCs F.2.1 PURPOSE The purpose of this section is to describe the process to perform the peer review of the selected structures, systems, and components, (SSCs) that were included in the Seismic Walkdown Equipment List (SWEL).F.2.2 PEER REVIEW ACTIVITY -SELECTION OF SSCs The guidance in Section 3 of the EPRI Seismic Walkdown Guidance (Reference

1) was used as the basis for this review.This peer review of SWEL 1 was based on reviews of preliminary documents provided by the SWEL preparer, Mr. Tom King. Additionally, the Peer Reviewers interviewed Mr. King. Reference 1 Appendix F: "Checklist for Peer Review of SSC Selection," was used by the Peer Reviewers to guide their review.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 o Reactor Coolant Pressure Control o Reactor Coolant Inventory Control o Decay Heat Removal o Containment Function 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.

• 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 an appropriate sample of items that represent each attribute/consideration identified Limerick Generating Station Unit 2 MPR-3801, Revision 1 Correspondence No.: RS-12-171 F-6 above. The justification for this conclusion is: a) Based on a review of the UFSAR and SWEL 1 list, it was determined that an appropriate variety of equipment and systems are represented (e.g., EDG, HPCI, RCIC, Core Spray, RHR, CRD Scram Hydraulic, Emergency Service Water, and Batteries);

b) The "New and Replacement" equipment are indicated as such; c) A variety of location environments are included (e.g., Diesel Rooms, Reactor Building, Drywell, and Diesel Oil Storage Tank Underground Structure);

d) The SWEL identifies that there are no IPEEE Enhancement related equipment; and e) Risk Significant equipment items are clearly identified on the SWEL. Additional details for these conclusions are presented in Attachment 1: Peer Review Checklist for SWEL.There are no SWEL 2 items for Limerick Unit 2. To confirm the appropriateness of this conclusion, the following actions were completed in the peer review process: Verification that spent fuel pool (SFP) related Seismic Category I SSCs were considered and appropriate justification was documented for why these items were not added to the SWEL 2.This peer review determined that the few spent fuel pool related items that are Seismic Category I were given appropriate consideration and justification for exclusion from SWEL 2.Verification that the potential for rapid drain down of the SFP, including potential for siphoning, was considered in accordance with the Reference 1 guidance, and appropriate justification was documented for no items being added to SWEL 2.This peer review determined that appropriate consideration and justification were provided for there being no items identified that could result in rapid drain down. There is no equipment that could result in rapid draindown and Fuel Pool Cooling and Cleanup piping includes holes drilled 1 foot 6 inches below the normal fuel pool level specifically intended to prevent siphoning (See Section 4.3 of the Walkdown Report as well as Attachment 1 to this Appendix).

F.2.3 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 Section 3 of Reference 1.The Peer Review Checklist is provided as Attachment 1 to this Appendix with additional observations documented as appropriate.

One of the observations was that no equipment located in the primary containment was represented on the final SWEL. A subsequent decision was made based on industry input and benchmarking to include components within the Primary Containment.

Another observation was that in cases where ventilation fans were included in the SWEL, any associated dampers should also be included because operation of the dampers is critical to operation of the fans.This peer review resulted in no additional findings.F.2.4 RESOLUTION OF PEER REVIEW COMMENTS -SELECTION OF SSCS All comments requiring resolution were incorporated prior to completion of this peer review.Limerick Generating Station Unit 2 F-7 MPR-3801, Revision 1 Correspondence No.: RS-12-171 F.

2.5 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 I equipment and systems to meet the objectives of the NRC 50.54(f) Letter.-VxAt;C.,& -BRA L Peer Reviewer: Date 10/10/2012 Peer Reviewer: Date 10/10/2012 Limerick Generating Station Unit 2 MPR-3801, Revision 1 Correspondence No.: RS-12-171 F-8 F.3 Review of Sample Checklist

Peer Reviewer: Date 10/10/2012 Limerick Generating Station Unit 2 MPR-3801, Revision 1 Correspondence No.: RS-12-171 F-13 F.4 Review of Licensing Basis Evaluations There were no instances identified during the walkdowns where evaluated components could not readily be shown to meet the plant seismic licensing basis. Accordingly, no licensing basis evaluations to determine if equipment complied with current seismic licensing basis requirements were required.

However, there were some anomalies or conditions adverse to quality that were identified during the walkdowns.

Tables 5-2 and 5-3 in the main body of the report provide a list of the anomalies encountered during the Unit 2 seismic walkdown inspections and how they were addressed.

The Peer Review Team had no issues or concerns associated with any of the conditions identified, operability determinations performed, or proposed actions to resolve the issues.-V24e4-BRAL Peer Reviewer: Date 10/12/2012 Limerick Generating Station Unit 2 MPR-3801, Revision 1 Correspondence No.: RS-12-171 F-14 F/=5 References

EPRI Technical Report 1025286, Seismic Walkdown Guidance for Resolution of Fukushima Near-Term Task Force Recommendation 2.3: Seismic, dated June 2012.Limerick Generating Station Unit 2 MPR-3801, Revision 1 Correspondence No.: RS-12-171 F-1 5 Attachment 1: Peer Review Checklist for SWEL Peer Review Checklist for SWEL -Limerick Generating Station Unit 2 Instructions for Completing Checklist This peer review checklist may be used to document the review of the Seismic Walkdown Equipment List (SWEL) in accordance with Section 6: Peer Review. The space below each question in this checklist should be used to describe any findings identified during the peer review process and how the SWEL may have changed to address those findings.

Additional space is provided at the end of this checklist for documenting other comments.1. Were the five safety functions adequately represented in the SWEL I selection?

YZ NEI All five safety functions were included in the SWEL Selection.

2. Does SWEL 1 include an appropriate representation of items having the following sample selection attributes:

a. Various types of systems? YE NEI A wide variety of systems were represented including, Emergency Diesel Generators and Auxiliaries, Residual Heat Removal, Reactor Core Isolation Cooling, Core Spray, High Pressure Coolant Injection, Control Drive Hydraulic, Low Pressure Coolant Injection, 125 VDC, 120 VAC, 480 VAC, Main Steam, and Automatic Depressurization.

b. Major new and replacement equipment?

Y2 NEI The SWEL identifies new equipment that has been added to the plant and is within the scope of the walkdowns including 2BE205 (2B RHR Heat Exchanger), and 2AP514 (Diesel Generator Fuel Oil Transfer Pump). Limerick Unit 2 has not made significant modifications to Seismic Category I equipment.

Accordingly, there is not a large number of new and replacement components.

c. Various types of equipment?

YZ NEI All of the IPEEE equipment classes are represented with the exception of Class#11, Motor Generators.

There are no Seismic Category I motor generators at Limerick Unit 2.d. Various environments?

YO NEI Equipment in various environments including the Diesel Generator Building, Reactor Building, Control Structure and Drywell are included.

Note that walkdowns of equipment in the Drywell have been deferred until a refuel outage when the drywell can be accessed.e. Equipment enhanced based on the findings of the IPEEE (or equivalent)

YIl NEI program?There was no equipment that was enhanced based on findings of the IPEEE (see Walkdown Report Sections 4.2 and 7 and Walkdown Report References 13 and 14).Limerick Generating Station Unit 2 F-16 MPR-3801, Revision 1 Correspondence No.: RS-12-171 Peer Review Checklist for SWEL -Limerick Generating Station Unit 2 f Were risk insights considered in the development of SWEL 1? YI NEI The plant Probabilistic Risk Assessment (PRA) was reviewed and used to guide selection of the components on SWEL 1. Specifically, the relative risk significance of candidate components including the Risk Achievement Worth (RAW) and Fussell-Vesely importance for a Loss of Off-Site Power (LOOP) scenario from the intemal plant PRA were used (See Section 4.2 of the report).3. For SWEL 2: a. Were spent fuel pool related items considered, and if applicable included in YI NEI SWEL 2?Both parts of SWEL 2, assessment of Seismic Category I spent fuel pool (SFP)related equipment and equipment that could potentially result in rapid drain-down of the SFP were considered.

See documentation of SFP item review in Section 4.3 of the Report.b. Was an appropriate justification documented for spent fuel pool related items YS NEI not included in SWEL 2?As noted in Section 4.3 of the report, the SFP-related Seismic Category I equipment includes the Residual Heat Removal (RHR) cross-tie, the Emergency Service Water (ESW) make-up supply line and the Spent Fuel Pool Skimmer Tank. The RHR and ESW components are spool pieces and manual valves that are in-line components with minimal extension of their operators (e.g., handwheels).

These components are determined to be seismically adequate based on explicit analysis in accordance with ASME Codes rules for piping. Additionally, due to their inherent seismic ruggedness and performance in strong-motion earthquakes, manual valves are not included in the EPRI Guidance Document (Reference

1) classes of equipment requiring walkdowns.

The SFP Skimmer Tanks are in a high radiation area and are not accessible during normal operation or during a refueling outage.Section 4.3 also includes appropriate justification that there are no items of equipment that could cause rapid drain-down due to lack of penetrations within about 10 feet above the top of the fuel racks, and there are adequate anti-syphon features included in piping that terminate within a few feet of the tops of the fuel racks.4. Provide any other comments related to the peer review of the SWELs.The Peer Review team had some comments regarding the safety functions for some of the components included in the SWEL. In addition, the SWEL included a number of ventilation fans, but not the dampers that must open to allow the fans to deliver their required air flow. The Peer Review team identified that the dampers must be evaluated in addition to the fans to assure that fan design basis function is maintained during a seismic event. Input has been provided to the preparer of the SWEL and corrections have been made.5. Have all peer review comments been adequately addressed in the final SWEL?YZ NE Limerick Generating Station Unit 2 MPR-3801, Revision 1 Correspondence No.: RS-12-171 F-17 Peer Review Checklist for SWEL -Limerick Generating Station Unit 2 Patrick Butler, P.
