DPR-65 NPF-49 DOMINION NUCLEAR CONNECTICUT. INC. MILLSTONE POWER STATION UNITS 2 AND 3 REPORT IN RESPONSE TO MARCH 12, 2012 INFORMATION REQUEST REGARDING SEISMIC ASPECTS OF RECOMMENDATION 2.3 On March 12, 2012, the Nuclear Regulatory Commission (NRC) issued, "Request for Information Pursuant to Title 10 of the Code of Federal Regulations 50.54(f) Regarding Recommendations 2.1, 2.3, and 9.3, of the Near-Term Task Force Review of Insights from the Fukushima Dai-ichi Accident," to all power reactor licensees and holders of construction permits in active or deferred status. Seismic Recommendation 2.3 requires licensees to conduct seismic walkdowns at their plants to identify and address plant specific degraded, nonconforming, or unanalyzed conditions such that the nuclear power plant can respond to external events. For Seismic Recommendation 2.3, Enclosure 3 of the letter states that within 180 days of the NRC's endorsement of the walkdown process, each licensee will submit its final response. The response should include a list of any areas that are unable to be inspected due to inaccessibility and a schedule for when the walkdowns will be completed. In a letter dated May 31, 2012, the NRC endorsed EPRI 1025286, "Seismic Walkdown Guidance: For Resolution of Fukushima Near-Term Task Force Recommendation 2.3: Seismic," which Dominion Nuclear Connecticut, Inc. (DNC) used to conduct its seismic walkdowns for Millstone Power Station (MPS) Units 2 and 3. Attachments 1 and 2, on the attached compact disc, provide the walkdown reports as DNC's response to Seismic Recommendation 2.3 for MPS2 and MPS3, respectively. Attachment 3 provides a list of items for which inspections could not be completed due to inaccessibility and a schedule of when the walkdowns for these items will be completed. A supplemental submittal will be provided to the NRC with the results of the deferred seismic walkdowns for MPS2 and MPS3 by August 30, 2014.

Dominion Nuclear Connecticut, Inc. Millstone Power Station Unit 2 Seismic Walkdown Summary Report Resolution of Fukushima Near-Term Task Force Recommendation 2.3: Seismic November, 2012

Millstone Power Station Unit 2 NTTF 2.3 Seismic Walkdown Summary Report Executive Summary On March 12, 2012, the U.S. Nuclear Regulatory Commission (NRC) staff issued requests for information pursuant to 10 CFR 50.54(f) related to the Near Term Task Force (NTTF) recommendations. Enclosure 3 of the NRCs 50.54(f) letter requested utilities to provide information related to NTTF Recommendation 2.3: Seismic, as amended by the Staff Requirements Memoranda (SRM) associated with SECY-11-0124 and SECY-11-0137. The nuclear power industry and the NRC cooperatively developed guidelines and procedures to perform the seismic walkdowns. The resulting EPRI Report No. 1025286, Seismic Walkdown Guidance for Resolution of Fukushima Near-Term Task Force Recommendation 2.3: Seismic (EPRI 1025286) provides guidance and procedures for performing the seismic walkdowns. Dominion followed the EPRI 1025286 guidance in developing the Seismic Walkdown Equipment List (SWEL), performing the Millstone Power Station (MPS) Unit 2 seismic walkdowns and developing the submittal report. Seismic walkdowns of accessible items have been completed. Some items included on the SWEL were not sufficiently accessible to complete the walkdown inspection. Walkdowns for these items are planned to be completed by the end of the next scheduled refueling outage (Spring 2014). A revised Summary Report will be issued following completion of the seismic walkdowns. By completing and documenting the requested seismic walkdowns for MPS Unit 2, Dominion has met the objectives of the NRC request for information related to NTTF Recommendation 2.3: Seismic. Potentially adverse conditions identified during the completed seismic walkdowns and area walk-bys were submitted as Condition Reports (CRs) in the MPS Unit 2 corrective action program (CAP). To date, no significant issues that challenged the MPS Unit 2 seismic licensing or design basis have been identified as a result of the walkdowns. ii

Millstone Power Station Unit 2 NTTF 2.3 Seismic Walkdown Summary Report

Background

Following the accident at the Fukushima Daiichi nuclear power plant resulting from the March 11, 2011, Great Tohoku Earthquake and subsequent tsunami, the Nuclear Regulatory Commission (NRC) established the Near Term Task Force (NTTF) in response to Commission direction. The NTTF was tasked with conducting a review of NRC regulations and processes and determining if the NRC should make additional improvements. A set of recommendations made by the task force was included in a report provided to the Commission. Although the NRC concluded that continued plant operation did not pose an imminent risk to public health and safety, the Commission directed the NRC staff (in the Staff Requirements Memorandum (SRM) to SECY-1 1-0093) to determine those recommendations that should be implemented without unnecessary delay. In SECY-1"1-0124, the NRC staff identified the NTTF recommendations that should be implemented without delay, including the development of information requests to be made under 10 CFR 50.54(f). The NRC issued the requests for information pursuant to 10 CFR 50.54(f) on March 12, 2012 related to the following NTTF recommendations (Reference 1):

Recommendation 2.1: Seismic

    "   Recommendation      2.1: Flooding
    "   Recommendation      2.3: Seismic
    "   Recommendation      2.3: Flooding

Recommendation 9.3: Emergency Preparedness Enclosure 3 of the NRC's 50.54(f) letter addressed providing information related to NTTF Recommendation 2.3: Seismic, as amended by the SRMs associated with SECY-11-0124 and SECY-1 1-0137. Enclosure 3 requested that licensees:

1. Develop a methodology and acceptance criteria for seismic walkdowns to be endorsed by the NRC staff,

2. Perform seismic walkdowns using the NRC-endorsed walkdown methodology,

3. Identify and address degraded, nonconforming, or unanalyzed conditions through a corrective action program, and

4. Verify the adequacy of licensee monitoring and maintenance procedures.

The nuclear power industry and the NRC agreed to cooperate in the development of guidelines and procedures to perform the seismic walkdowns. The resulting EPRI Report No. 1025286, Seismic Walkdown Guidance for Resolution of Fukushima Near-Term Task Force Recommendation 2.3: Seismic (EPRI 1025286) (Reference 2) provides guidance and procedures for performing the seismic walkdowns. The guidance addresses selection of personnel, selection of a sample of structures, systems, and components (SSCs) that represent a diversity of component types and ensures inclusion of components from critical systems and functions as described in the NRCs 50.54(f) letter, conduct of the walkdowns, evaluations against the plant seismic licensing basis, and reporting requirements. EPRI 1025286 also includes checklists to be used by the seismic walkdown engineers for seismic evaluations. The guidance contained in EPRI 1025286 was developed to meet NRC's objectives, and in a letter dated May 31, 2012 (Reference 3), the NRC confirmed that the EPRI 1025286 guidance iv

Millstone Power Station Unit 2 NTTF 2.3 Seismic Walkdown Summary Report directs licensees to perform walkdowns in a manner that will address Requested Information Items 1.a through 1.g in the 50.54(f) letter. The NRC staff also confirmed that Section 8, "Submittal Report," of the EPRI 1025286 guidance outlines the appropriate information to be submitted in response to Requested Information Items 2.a through 2.f. of Enclosure 3 of the 50.54(f) letter. Dominion used the EPRI 1025286 guidance in developing and performing the seismic walkdowns at Millstone Power Station (MPS) Unit 2 in response to the NRC's 50.54(f) letter. In addition, Dominion followed the EPRI 1025286 Section 8 guidance for the development of this report. V

Millstone Power Station Unit 2 NTTF 2.3 Seismic Walkdown Summary Report 1.0 Seismic Licensing Basis Summary The seismic licensing basis for MPS Unit 2 is documented in the Final Safety Analysis Report (FSAR) (Reference 4). The FSAR describes the design basis earthquake (DBE) loads and their application to structures and components. The seismic design basis functions are in FSAR Chapter 5, Structures. FSAR Section 5.2.2.1.5 states that structural function is ensured to the DBE, which has a peak horizontal ground acceleration of 0.17g and vertical ground acceleration of 0.1 g. Earthquake loads are predicated upon an operating basis earthquake (OBE) at the site having a horizontal ground acceleration of 0.09g and a vertical acceleration of 0.06g. FSAR Chapter 5 contains commitments to the General Design Criteria (GDC) in Appendix A of 10 CFR Part 50. The DBE is defined as the maximum credible earthquake at the plant site that can reasonably be predicted from geologic and seismic evidence. The Nuclear Steam Supply System (NSSS) is designed to withstand the loads imposed by the maximum hypothetical accident and the maximum seismic disturbance without loss of functions required for safe reactor shutdown and emergency core cooling. Category I structures are designed to withstand appropriate seismic and other applicable loads without loss of function, which could result in a release of radioactivity to the site boundary in excess of the 10 CFR 100 guidelines. The design philosophy for equipment component seismic design has been subject to significant changes since issuance of the original operating license. The seismic design basis was verified during the design phase by analyzing lumped-mass stick models for each of the buildings. Once built, IEEE 344-1971 provided direction for analysis and testing procedures which demonstrated that equipment could meet performance requirements in the event of a DBE. Subsequent to the original plant design, MPS Unit 2 implemented several plant systems upgrades with commitments to IEEE 344-1975 as the seismic design basis. MPS Unit 2 seismic qualification was reviewed through two programs in the late 1980's and early 1990's. In 1987, the NRC issued Generic Letter (GL) 87-02 to provide guidance to licensees for Unresolved Safety Issue (USI) A-46 "Seismic Qualification of Equipment in Operating Plants." In 1991, the NRC issued GL 88-20, Supplement 4, requesting licensees to perform an Individual Plant Examination of External Events (IPEEEE) for severe accident vulnerabilities in accordance with the guidelines provided in NUREG-1407. The MPS Unit 2 IPEEE and USI A-46 programs were integrated to perform seismic walkdowns of SSCs. Seismic review teams conducted walkdowns following the Seismic Qualification Utility Group (SQUG) Generic Implementation Procedure (GIP) and procedures detailed in EPRI NP-6041. A summary report of the results of the MPS Unit 2 IPEEE program was submitted to the NRC in 1995 (Reference 5) followed by the USI A-46 walkdown summary report in 1996 (Reference 6). Following the USI A-46 program, MPS Unit 2 modified the FSAR to allow the use of SQUG GIP methodology as an alternative to the existing FSAR methods for the seismic design and verification of modified, new, and replacement equipment. Lastly, MPS Unit 2 modified the FSAR to allow the use of the EPRI STERI (Seismic Technical Evaluation of Replacement Items TR-104871) process to demonstrate that seismically rugged or insensitive replacement items exhibit seismic performance equivalent to original items. Codes, standards, and methods related to the definition of the DBE and the design of structures and components for MPS Unit 2 can be found in FSAR Sections 2.6, 4.5.2, and Chapter 5. 1-1

Millstone Power Station Unit 2 NTTF 2.3 Seismic Walkdown Summary Report 3.0 SSC Selection 3.1 Purpose This section describes the process used to develop the seismic walkdown equipment list (SWEL) and documents the resulting SWEL and Area Walk-by list in response to NRC's 10 CFR 50.54(f) letter dated March 12, 2012 (Reference 1). The SWEL was developed using the guidance provided in EPRI 1025286 (Reference 2) and defines the scope of the seismic walkdowns. 3.2 Methodology EPRI 1025286, Section 3, Selection of SSCs, describes the process used to identify items to be included in the SWEL. In general, the SWEL is comprised of two groups of items. The first is a sample of components from the seismic safe shutdown equipment list (SSEL). The other is a sample of components associated with the spent fuel pool. These lists are designated as SWEL 1 and SWEL 2, respectively. SWEL 1 and SWEL 2 are combined to form the SWEL, which defines the overall scope of equipment used as input to the seismic walkdowns. Additional information regarding the process used to develop the SWEL is provided below. SWEL 1 Development The base equipment list used as a starting point for development of the SWEL 1 list was the SSEL developed to address NRC Generic Letter 87-02, Verification of Seismic Adequacy of Mechanical and Electrical Equipment in Operating Reactors, Unresolved Safety Issue (USI) A-46. The development of the SSEL included consideration of the following four safety functions:

Reactor reactivity control
Reactor coolant pressure control
Reactor coolant inventory control
Decay heat removal Consistent with the guidance in EPRI 1025286, the SSEL was reviewed for items that support the following safety function:
Containment function SWEL 1 was developed by applying the following five sample selection attributes, defined in EPRI 1025286, to the SSEL. The required sample size for SWEL 1 was at between 90 and 120 items. The method of application for each attribute is summarized below:

1. A variety of types of systems. Sample items were selected to represent a broad range of frontline and support systems included on the SSEL.

2. Major new and replacement equipment. A review of the equipment on the SSEL was performed by experienced system engineers, design engineers, and plant operators to identify major new or replacement equipment installed within the last 15 years, consistent with EPRI 1025286 guidance. These items were identified for inclusion in the selection of the samples for SWEL 1.

3-1

Millstone Power Station Unit 2 NTTF 2.3 Seismic Walkdown Summary Report

3. A variety of types of equipment. At least one item from each of the classes of equipment listed in EPRI 1025286, Appendix B, Classes of Equipment was included on SWEL 1 to provide a sample selection of a variety of equipment types. Where no items were listed on the SSEL for a specific class of equipment, no items in that equipment class were selected for SWEL 1.

4. A variety of environments. Sample items were selected from different locations in the plant to include various environments (hot, cold, dry, wet) and inside and outside installations.

5. Equipment enhanced due to vulnerabilities identified durinq the IPEEE pro ram. The USI A-46 and IPEEE program documentation was reviewed to determine equipment that had been modified or otherwise enhanced to reduce USI A-46 and IPEEE vulnerabilities.

These items were identified for inclusion in the selection of the sample for SWEL 1. For each item on SWEL 1, the applicable supported safety function(s) were determined as a confirmation that the five safety functions are adequately represented. In addition, risk significant items on the SWEL 1 list are identified as confirmation that risk insights are adequately considered in the development of SWEL 1. SWEL 2 Development SWEL 2 was developed based on a review of systems associated with the spent fuel pool (SFP) that are Seismic Category I or components whose failure could result in a rapid drain-down of the water level in the SFP to less than ten feet above the fuel. For Seismic Category I systems associated with the SFP, a sample of components was identified using selection criteria similar to that described for SWEL 1. Any components whose failure could result in rapid drain-down of the SEP were to be identified and evaluated for addition to SWEL 2. Identified components that met the criteria for inclusion in the seismic walkdowns were to be added to SWEL 2. If no component failures were identified that could result in rapid drain-down of the SFP, no components were added to SWEL 2, and the basis for this conclusion was described. SWEL The SWEL was developed by combining the items on SWEL 1 and SWEL 2. The items on the SWEL were reviewed to determine the population of items with anchorage, and at least 50% of those items were selected for a configuration verification of the installed anchorage during the associated seismic walkdown. The SWEL serves as the input to the seismic walkdowns conducted in accordance with EPRI 1025286 Section 4, Seismic Walkdowns and Area Walk-Bys. A walk-by area is defined as the room containing SWEL item(s), or in the case of a large open space, the area within a 35 foot radius around a SWEL item. Walk-by areas are defined to ensure that all items on the SWEL are included within a walk-by area. 3-2

Millstone Power Station Unit 2 NTTF 2.3 Seismic Walkdown Summary Report 3.3 Results The methodology described in Section 3.2 was applied to develop the SWEL and the Area Walk-by list. The results of the implementation of this methodology are provided below. The SWEL was developed by personnel meeting the qualifications for equipment selection personnel described in Section 2.1. Qualifications of personnel involved in the development of the SWEL are identified in Appendix A. SWEL 1 The SSEL developed to address USI A-46 was the starting point (termed Base List 1 in EPRI 1025286) for development of the SWEL 1. The SSEL was submitted to the NRC in Reference 6. The five sample selection attributes, described in Section 3.1, were then applied to the SSEL. The results are summarized for each attribute below:

1. A variety of types of systems. Sample items were selected to represent a broad range of frontline and support systems included on the SSEL. The number of selected items associated with each of the represented systems is provided in Appendix B.

2. Major new and replacement equipment. A review of the equipment on the SSEL was performed by experienced system engineers, design engineers, and plant operators to identify major new or replacement equipment installed within the last 15 years. The review was based on plant design change records, maintenance history, and reviewer experience. A sample of these items is included in SWEL 1.

3. A variety of types of equipment. At least one item from each of the classes of equipment listed in EPRI 1025286, Appendix B: Classes of Equipment was included in SWEL 1 to provide a sample selection of a variety of equipment types. The number of items from each of the equipment classes is identified in Appendix B. There were no items listed on the SSEL for equipment classes 12 and 13.

4. A variety of environments. Sample items were selected from different locations in the plant to include various environments (hot, cold, dry, wet). The installed location is identified for each of the SWEL 1 items, which provides an indication of the operating environment for the item.

5. Equipment enhanced due to vulnerabilities identified durinq the IPEEE program. The USI A-46 program documentation was reviewed to determine equipment that had been modified or otherwise enhanced to reduce seismic vulnerabilities. 17 of these items are included on the SWEL 1 list.

The resulting sample size of the equipment for the SWEL 1 list was 99 items. For each item on the list, the applicable supported safety function(s), listed below, were identified and indicated:

Reactor reactivity control
Reactor coolant pressure control

    "    Reactor coolant inventory control
    "    Decay heat removal
    "    Containment function 3-3

Millstone Power Station Unit 2 NTTF 2.3 Seismic Walkdown Summary Report SWEL 2 SWEL 2 was developed based on a review of systems associated with the spent fuel pool (SFP) that are Seismic Category I or components whose failure could result in a rapid drain-down of the water in the SFP to less than ten feet above the top of the fuel. The review was supported by a licensed operator and knowledgeable system engineers. The following Seismic Category I system associated with the SFP was identified:

Spent Fuel Pool Cooling System The system was reviewed using the walkdown item sample selection criteria similar to that used for SWEL 1, consistent with the guidance in EPRI 1025286. The following components were selected for inclusion on the MPS Unit 2 SWEL 2:

    -   M2PI13A Spent Fuel Pool Cooling Pump A
    -   M2X20A Spent Fuel Pool Heat Exchanger A Note: M2X20A Spent Fuel Pool Heat Exchanger A was also selected for SWEL 1 since this item was on the seismic SSEL (Base List 1).

Base List 2 and the items identified for inclusion on SWEL 2 are identified in Appendix B. Rapid Drain-down Systems interfacing with the SFP were reviewed to identify any components that could, upon failure, result in rapid drain-down of the SFP water level to below ten feet above the top of the fuel. As described in MPS Unit 2 FSAR Section 9.5 (Reference 4), the SFP has been designed to prevent cooling water inventory loss. All connections penetrate theý wall near the normal operating level so the pool cannot be gravity drained by leaking pumps, valves, or other equipment. Additionally, the cooling water return piping, which extends to the pool bottom, is provided with anti-siphon features. The piping configuration and siphon breaks combine to preclude inadvertent draining of the SFP due to leaks in interfacing piping and equipment. Therefore, there are no components that could, upon failure, result in rapid drain-down of the SFP water level to below ten feet above the top of the fuel and no components have been added to SWEL 2 for this criterion. SWEL The SWEL was developed by combining the items on SWEL 1 and SWEL 2. The SWEL is provided in Appendix B. All items on the list are from SWEL 1 except those items indicated by footnote as originating from SWEL 2. The items on the SWEL were reviewed to identify those that included anchorage (i.e., items that were not line-mounted equipment, such as valves). 58 of the 67 items that included anchorage (86%) were selected for confirmation that the as-installed equipment anchorage is consistent with plant documentation of the anchorage design. The anchorage items selected for confirmation are indicated by a note on the SWEL. 3-4

Millstone Power Station Unit 2 NTTF 2.3 Seismic Walkdown Summary Report In addition, risk significant items on the SWEL were identified. This information was reviewed by the PRA subject matter expert as confirmation that risk insights were adequately considered in the development of the SWEL. As a result, 68 of the 100 items on the SWEL were identified as being risk significant. This list is the input to the seismic walkdowns conducted in accordance with EPRI 1025286, Section 4, Seismic Walkdowns and Area Walk-Bys. Walk-by areas were identified to include all of the items on the SWEL and are listed in Appendix B. 3.4 Inaccessible Items In the process of selecting SSCs to be included on the SWEL, items that were accessible and have visible anchorage were selected wherever possible. However, there were 5 items included on the SWEL that were not sufficiently accessible to complete the walkdown inspection. These items are listed in Table 3-1 below and indicated by a footnote on the SWEL (Appendix B). The walkdowns for these items are planned to be completed by the end of the next scheduled refueling outage (Spring 2014).

Millstone Power Station Unit 2 NTTF 2.3 Seismic Walkdown Summary Report 4.0 Seismic Walkdowns and Area Walk-Bys The seismic walkdowns and area walk-bys were performed consistent with the guidance provided in EPRI 1025286 (Reference 2). A site-specific procedure was developed to implement the EPRI 1025286 seismic walkdown guidance for conducting and documenting the seismic walkdowns. A walkdown package was prepared for each component listed on the SWEL and for each area walk-by to be performed. Each package included a seismic walkdown checklist (SWC) or an area walk-by checklist (AWC), and the drawing(s) showing equipment location, plant documentation showing the anchorage details for each SWEL item requiring anchorage configuration verification, and documents from prior seismic walkdowns (e.g., Seismic Evaluation Work Sheets (SEWS) from USI A-46 walkdowns), as applicable. A hardcopy of the package was available for the SWEs during performance of the equipment walkdown or area walk-by. The seismic walkdowns and area walk-bys were performed by walkdown teams, which consisted of at least two (2) qualified SWEs. For the seismic walkdowns, the SWEs focused on the following adverse seismic conditions associated with each item of equipment as described in the EPRI 1025286 guidance:

adverse anchorage conditions,
adverse seismic spatial interactions, and

    " other adverse seismic conditions.

The purpose of the area walk-bys was to identify potentially adverse seismic conditions associated with other SSCs located in the vicinity of the SWEL items. For the area walk-bys, SWEs focused on the following potentially adverse seismic conditions as described in the EPRI 1025286 guidance:

    " anchorage conditions (if visible without opening equipment),
    " significantly degraded equipment in the area,

condition of cable/conduit raceways, including condition of supports or fill conditions, and HVAC ducting,

    " potential adverse seismic interactions including those that could cause flooding, spray, or a fire in the area, and
    " housekeeping items that could cause adverse seismic interactions.

During the walkdown or walk-by, the walkdown teams discussed conditions and/or any findings in the field, reached agreement on the results of the walkdown, and documented results of the seismic walkdowns and area walk-bys on the checklists. The results of the completed seismic walkdowns are documented on SWCs, which are included as Appendix C. The results of the completed area walk-bys are documented on AWCs, which are included as Appendix D. For electrical cabinet internal inspection of motor control centers (MCC) that included several breaker cubicles (buckets), a sample of the breaker cubicles were inspected as described on the applicable SWC for the item. The use of a sample inspection for these items is consistent with the overall sampling approach applied to the NTTF 2.3 Seismic walkdowns, and provides reasonable assurance that visibly accessible internal components mountings are adequate. Inspecting a sample of MCC breaker cubicles adequately confirmed the condition of internal component mountings since the fastenings for components within MCCs are not subject to 4-1

Millstone Power Station Unit 2 NTTF 2.3 Seismic Walkdown Summary Report significant environmentally-induced degradation based on their installed location and the maintenance on these items is controlled by station procedures. The SWEL includes 100 items to be walked down and 36 area walk-bys were defined. Of these, 95 walkdowns and 36 area walk-bys have been completed. The remaining 5 walkdowns have been deferred because the component was not sufficiently accessible to complete the walkdown inspection and walkdown checklists are not included in this report for those items. The schedule for completion of these deferred seismic walkdowns is described in Section 3.4. Table 4-1 lists potentially adverse seismic conditions identified during the completed seismic walkdowns and area walk-bys. The items listed in Table 4-1 were submitted as Condition Reports (CRs) in the station corrective action program (CAP). Table 4-1 summarizes the potentially adverse seismic conditions, describes how the condition has been addressed, and provides the current status of the resolution. A low threshold was used to identify and document potential adverse conditions. In addition to items listed in Table 4-1, non-seismic related potentially adverse conditions, such as various housekeeping and material condition items, were identified by the walkdown teams and addressed through the CAP. No significant issues that challenged the MPS Unit 2 seismic licensing or design basis were identified as a result of the walkdowns completed to date. As indicated in Table 4-1, no planned or newly installed changes to the plant are required to resolve the items identified during the walkdowns. 4-2

Millstone Power Station Unit 2 NTTF 2.3 Seismic Walkdown Summary Report 6.0 IPEEE Vulnerabilities On June 28, 1991, the NRC issued Generic Letter (GL) 88-20, Supplement 4 (with NUREG-1407, Procedural and Submittal Guidance) requesting each licensee to perform an individual plant examination of external events (IPEEE) to examine the plant-specific relationship of external events to severe accidents, identify any severe accident vulnerabilities, and to report the results to the Commission together with any licensee-determined improvements and corrective actions. The results of the IPEEE Program for MPS Unit 2 were submitted in the Millstone Unit 2 IPEEE Summary Report dated December 1995 (Reference 5), which indicated that MPS Unit 2 had a relatively low risk from external events. Table 7.1-1, Opportunities for Safety Enhancements, of the MPS Unit 2 IPEEE Summary Report provides the equipment outliers identified during walkdown evaluations for the IPEEE review. Table 7.1-1 indicated the items that remained unresolved at the time of the report submittal. An updated status of the items in the IPEEE Report Table 7.1-1 was provided in a letter dated December 31, 1998 (Reference 7). Table 6-1 provides the current status of the seismic-related items from IPEEE Report Table 7.1-1 that were indicated as OPEN in the update provided in Reference 7. The MPS Unit 2 configuration management program has maintained the equipment modifications and programmatic changes implemented to eliminate or reduce the seismic vulnerabilities identified during the IPEEE program. 6-1

2. Sample of Seismic Walkdown Checklist (SWC) and Area Walkdown Checklist (AWC)

The Peer Review Team reviewed a sample of walkdown results and concluded that the SWCs and AWCs were completed in accordance with the EPRI 1025286 guidance.

a. Packages - The Peer Review Team reviewed a sample of the seismic walkdown documentation packages prepared before walkdowns were performed. These walkdown packages were reviewed to ensure the seismic walkdown checklist and related documentation (e.g., Screening Evaluation Work Sheet (SEWS), anchorage details) were included. The packages were determined to be adequate to support the walkdowns.

b. SWC/AWC - There are 100 SWC documentation packages. 47 SWCs were peer reviewed representing 47% of the total SWCs. This exceeds the EPRI 1025286 requirement for a 10 - 25 % sample. 16 AWCs from a total of 36 were peer reviewed 7-1

Millstone Power Station Unit 2 NTTF 2.3 Seismic Walkdown Summary Report representing 44% of the total. Overall, the SWC and AWC were determined to be appropriately detailed and complete.

c. Seismic Walkdown Engineers (SWEs) were interviewed by the Peer Review Team Lead to verify that they understood and followed the Guidance in EPRI 1025286, Section 4, Seismic Walkdowns and Area Walk-Bys. Results of the interviews indicated that each team understood and followed the EPRI guidance.

All peer review comments were minor and were adequately resolved.

3. Review of Licensing Basis Evaluations All potentially adverse seismic conditions identified during the walkdowns were entered into the CAP consistent with plant procedure. There were no Licensing Basis Evaluations, as defined in EPRI 1025286, performed that were in addition to the CAP reviews.

4. Review of Conditions Entered into CAP The threshold level at which field-identified conditions were entered in CAP was considered to be appropriate to ensure that potential licensing basis issues were documented and reviewed by Engineering and the Operations Shift Manager for operability concerns.

Appropriate functional organizations (e.g., Operations, Maintenance, and Site Engineering) were routinely consulted and engaged in the evaluation of potentially adverse seismic conditions.

5. Review of Submittal Report A review of the submittal report was performed by members of the Peer Review Team and it was determined that the objectives and requirements of the 50.54(f) L.etter were met.

Fireprotection line at Column E-19 is not laterallysupported and could impact the column in a seismic event. However, the vital chilled water pumps nearby are resistantto spray and would not be rendered inoperable if they were to be sprayed by afire suppression leak. In addition, the column that the suppression system may impact isfire coated. This coating would provide some cushion to mitigate any impact. Refer to CR484379.

Dominion Nuclear Connecticut, Inc. Millstone Power Station Unit 3 Seismic Walkdown Summary Report Resolution of Fukushima Near-Term Task Force Recommendation 2.3: Seismic November, 2012

Millstone Power Station Unit 3 NTTF 2.3 Seismic Walkdown Summary Report Executive Summary On March 12, 2012, the U.S. Nuclear Regulatory Commission (NRC) staff issued requests for information pursuant to 10 CFR 50.54(f) related to the Near Term Task Force (NTTF) recommendations. Enclosure 3 of the NRCs 50.54(f) letter requested utilities to provide information related to NTTF Recommendation 2.3: Seismic, as amended by the Staff Requirements Memoranda (SRM) associated with SECY-11-0124 and SECY-11-0137. The nuclear power industry and the NRC cooperatively developed guidelines and procedures to perform the seismic walkdowns. The resulting EPRI Report No. 1025286, Seismic Walkdown Guidance for Resolution of Fukushima Near-Term Task Force Recommendation 2.3: Seismic (EPRI 1025286) provides guidance and procedures for performing the seismic walkdowns. Dominion followed the EPRI 1025286 guidance in developing the Seismic Walkdown Equipment List (SWEL), performing the Millstone Power Station (MPS) Unit 3 seismic walkdowns, and developing the submittal report. Seismic walkdowns of accessible items have been completed. Some items included on the SWEL were not sufficiently accessible to complete the walkdown inspection. Walkdowns for these items are planned to be completed by the end of the next scheduled refueling outage (Spring 2013). A revised Summary Report will be issued following completion of the seismic walkdowns. By completing and documenting the requested seismic walkdowns for MPS Unit 3, Dominion has met the objectives of the NRC request for information related to NTTF Recommendation 2.3: Seismic. Potentially adverse conditions identified during the completed seismic walkdowns and area walk-bys were submitted as Condition Reports (CRs) in the MPS Unit 3 corrective action program (CAP). To date, no significant issues that challenged the MPS Unit 3 seismic licensing or design basis have been identified as a result of the walkdowns. ii

Millstone Power Station Unit 3 NTTF 2.3 Seismic Walkdown Summary Report

Background

Following the accident at the Fukushima Daiichi nuclear power plant resulting from the March 11, 2011, Great Tohoku Earthquake and subsequent tsunami, the Nuclear Regulatory Commission (NRC) established the Near Term Task Force (NTTF) in response to Commission direction. The NTTF was tasked with conducting a review of NRC regulations and processes and determining if the NRC should make additional improvements. A set of recommendations made by the task force was included in a report provided to the Commission. Although the NRC concluded that continued plant operation did not pose an imminent risk to public health and safety, the Commission directed the NRC staff (in the Staff Requirements Memorandum (SRM) to SECY-11-0093) to determine those recommendations that should be implemented without unnecessary delay. In SECY-11-0124, the NRC staff identified the NTTF recommendations that should be implemented without delay, including the development of information requests to be made under 10 CFR 50.54(f). The NRC issued the requests for information pursuant to 10 CFR 50.54(f) on March 12, 2012 related to the following NTTF recommendations (Reference 1):

Recommendation 2.1: Seismic
Recommendation 2.1: Flooding
Recommendation 2.3: Seismic
Recommendation 2.3: Flooding

    " Recommendation 9.3: Emergency Preparedness  of the NRC's 50.54(f) letter addressed providing information related to NTTF Recommendation 2.3: Seismic, as amended by the SRMs associated with SECY-1 1-0124 and SECY-1 1-0137. Enclosure 3 requested that licensees:

1. Develop a methodology and acceptance criteria for seismic walkdowns to be endorsed by the NRC staff,

2. Perform seismic walkdowns using the NRC-endorsed walkdown methodology,

3. Identify and address degraded, nonconforming, or unanalyzed conditions through a corrective action program, and

4. Verify the adequacy of licensee monitoring and maintenance procedures.

The nuclear power industry and the NRC agreed to cooperate in the development of guidelines and procedures to perform the seismic walkdowns. The resulting EPRI Report No. 1025286, Seismic Walkdown Guidance for Resolution of Fukushima Near-Term Task Force Recommendation 2.3: Seismic (EPRI 1025286) (Reference 2) provides guidance and procedures for performing the seismic walkdowns. The guidance addresses selection of personnel, selection of a sample of structures, systems, and components (SSCs) that represent a diversity of component types and ensures inclusion of components from critical systems and functions as described in the NRCs 50.54(f) letter, conduct of the walkdowns, evaluations against the plant seismic licensing basis, and reporting requirements. EPRI 1025286 also includes checklists to be used by the seismic walkdown engineers for seismic evaluations. iv

Millstone Power Station Unit 3 NTTF 2.3 Seismic Walkdown Summary Report The guidance contained in the EPRI 1025286 was developed to meet NRC's objectives, and in a letter dated May 31, 2012 (Reference 3), the NRC confirmed that the EPRI 1025286 guidance directs licensees to perform walkdowns in a manner that will address Requested Information Items l.a through 1.g in the 50.54(f) letter. The NRC staff also confirmed that Section 8, "Submittal Report," of the EPRI 1025286 guidance outlines the appropriate information to be submitted in response to Requested Information Items 2.a through 2.f. of Enclosure 3 of the 50.54(f) letter. Dominion used the EPRI 1025286 guidance in developing and performing the seismic walkdowns at Millstone Power Station (MPS) Unit 3 in response to the NRC's 50.54(f) letter.

Seismic Category I equipment has been classified in accordance with Regulatory Guide 1.29, Rev. 3, Seismic Design Classification. The FSAR describes the safe shutdown earthquake (SSE) loads and their application to structures and components. The SSE is defined as the maximum vibratory ground motion at the plant site that can reasonably be predicted from geologic and seismic evidence. The operating basis earthquake (OBE) is that earthquake which, considering the local geology and seismology, can be reasonably expected to occur during the plant life. A SSE of 0.17g and a 1/2 SSE value of 0.09g in the horizontal direction and two-thirds of these values in the vertical direction, input at the bedrock surface, have been used as the design bases for seismic loading. In accordance with 10 CFR 100, Appendix A, the operating basis earthquake is taken to be at least one half of the SSE, or 0.09g. The design for the SSE is intended to assure that the integrity of the reactor coolant pressure boundary is not compromised, that the capability to shut down the reactor and maintain it in a safe condition is not compromised, and that the capability to prevent or mitigate the consequences of accidents which could result in potential offsite exposures comparable to the guideline exposures of 10 CFR 100 is not compromised. For the OBE loading condition, the reactor coolant system is designed to be capable of continued safe operation. Safety Class 1 and 2 equipment are designed to withstand the forces of the OBE and SSE. For normal conditions plus OBE loadings, the resulting stresses are limited to allowable working stresses as defined in the ASME B&PV Code, Section III, Appendix XVII, for normal and upset conditions. For normal conditions plus SSE loadings, the stresses are limited to within the allowable values given by Subarticle NA 2110 for critical parts of the equipment which are required to maintain the capability of the equipment to perform its safety function. Permanent deformation is allowed for the loading combination which includes the SSE to the extent that there is no loss of any safety function. Equipment and components that use seismic testing as qualification basis conform to applicable industry standards, such as IEEE 344-1975. Qualification of Class 1E electrical equipment conforms to IEEE 344-1975. The FSAR sections most applicable to equipment qualification are: 0 3.7N3, Seismic Subsystem Analyses (NSSS Vendor supplied equipment) 0 3.7B3, Seismic Subsystem Analyses (non-NSSS Vendor supplied equipment)

3.10, Seismic Qualification of Seismic Category 1 Instrumentation and Electrical Equipment Nuclear steam supply system (NSSS) vendor qualification methods approved by the NRC are discussed further in FSAR Section 5.4.1. Seismic adequacy of non-NSSS Seismic Category 1 equipment is documented using Static Analysis, Dynamic Testing, and Testing including combinations of methods. The EPRI STERI process (Seismic Technical Evaluation of Replacement Items TR-104871) may be used to demonstrate that seismically rugged or insensitive replacement items exhibit seismic performance equivalent to original items.

Millstone Power Station Unit 3 NTTF 2.3 Seismic Walkdown Summary Report 3.0 SSC Selection 3.1 Purpose This section describes the process used to develop the seismic walkdown equipment list (SWEL), and documents the resulting SWEL and Area Walk-By list, in response to NRC's 10 CFR 50.54(f) letter dated March 12, 2012 (Reference 1). The SWEL was developed using the guidance provided in EPRI 1025286 (Reference 2) and defines the scope of the seismic walkdowns. 3.2 Methodology EPRI 1025286, Section 3, Selection of SSCs, describes the process used to identify items to be included on a SWEL. In general, the SWEL is comprised of two groups of items. The first is a sample of Seismic Category I components that support achieving safe shutdown and the other is a sample of components associated with the spent fuel pool. These lists are designated as SWEL 1 and SWEL 2, respectively. SWEL 1 and SWEL 2 are combined to form the SWEL, which defines the overall scope of equipment used as input to the seismic walkdowns. Additional information regarding the process used to develop the SWEL is provided below. SWEL 1 Development Selection of SWEL 1 components was performed by screening the MPS Unit 3 Seismic Category I equipment in a manner consistent with the equipment selection approach described in EPRI 1025286. The MPS Unit 3 Technical Requirements Manual (TRM) Section 7.6 (Reference 5), MPS Unit 3 Safety Functional Requirements Manual (SFRM) Section 4.3 (Reference 6), and MPS Unit 3 Master Equipment List Database were used to identify the frontline and support systems supporting Safety Grade Cold Shutdown (described in FSAR Section 5.4.7.2.3.5, Reference 4). MPS Unit 3 is licensed as a Safety Grade Cold Shutdown (SGCS) plant. The Seismic Category I frontline and support systems are those that support the following five safety functions:

   "    Reactor reactivity control 0    Reactor coolant pressure control

Reactor coolant inventory control

   "    Decay heat removal

Containment function Seismic Category I equipment within the frontline and support systems that support the above listed safety functions were identified. This list is termed Base List 1 in EPRI 1025286.

The SWEL 1 list was determined by applying the following five sample selection attributes, as applicable, defined in EPRI 1025286, to Base List 1. The required sample size for SWEL 1 was at between 90 and 120 items. The method of application for each attribute is summarized below:

1. A variety of types of systems. Sample items were selected to represent a broad range of frontline and support systems.

2. Maior new and replacement equipment (since the completion of IPEEE/USI A-46 evaluations). This attribute is not applicable because no previous seismic walkdowns 3-1

Millstone Power Station Unit 3 NTTF 2.3 Seismic Walkdown Summary Report or evaluations were performed at MPS Unit 3 in response to USI A-46 or IPEEE requirements.

3. A variety of types of equipment. At least one item from each of the classes of equipment listed in EPRI 1025286, Appendix B, Classes of Equipment was included on SWEL 1 to provide a sample selection of a variety of equipment types. Where there was no seismic category I items for a specific class of equipment, no items in that equipment class were selected for SWEL 1.

4. A variety of environments. Sample items were selected from different locations in the plant to include various environments (hot, cold, dry, wet) and inside and outside installations.

5. Equipment enhanced due to vulnerabilities identified during the IPEEE program. The MPS Unit 3 IPEEE documentation was reviewed to determine equipment that had been modified or otherwise enhanced to reduce IPEEE vulnerabilities.

For each item on SWEL 1, the applicable supported safety function(s) are identified as a confirmation that the five safety functions are adequately represented. In addition, risk significant items on the SWEL 1 list are identified as confirmation that risk insights are adequately considered in the development of SWEL 1. SWEL 2 Development SWEL 2 was developed based on a review of systems associated with the spent fuel pool (SFP) that are Seismic Category I or components whose failure could result in a rapid drain-down of the water level in the SFP to less than ten feet above the fuel. For Seismic Category I systems associated with the SFP, a sample of components was identified using selection criteria similar to that described for SWEL 1. Any components whose failure could result in rapid drain-down of the SEP were to be identified and evaluated for addition to SWEL 2. Identified components that met the criteria for inclusion in the seismic walkdowns were to be added to SWEL 2. If no component failures were identified that could result in rapid drain-down of the SFP, no components were added to SWEL 2, and the basis for this conclusion was described. SWEL The SWEL was developed by combining the items on SWEL 1 and SWEL 2. The items on the SWEL were reviewed to determine the population of' items with anchorage, and at least 50% of those items were selected for configuration verification of the installed anchorage during the associated seismic walkdown. The SWEL serves as the input to the seismic walkdowns conducted in accordance with EPRI 1025286 Section 4, Seismic Walkdowns and Area Walk-Bys. A walk-by area is defined as the room containing SWEL item(s), or in the case of a large open space, the area within a 35 foot radius around a SWEL item. Walk-by areas are defined to ensure that all items on the SWEL are included within a walk-by area. 3-2

Millstone Power Station Unit 3 NTTF 2.3 Seismic Walkdown Summary Report 3.3 Results The methodology described in Section 3.2 was applied to develop the SWEL and the Area Walk-by list. The results of the implementations of this methodology are provided below. The SWEL was developed by personnel meeting the qualifications for equipment selection personnel described in Section 2.1. Qualifications of personnel involved in the development of the SWEL are identified in Appendix A. SWEL 1 The methodology described in Section 3.2 was utilized to develop SWEL 1. Seismic Category I equipment within the frontline and support systems that support the five safety functions listed in Section 3.2 were identified and are listed in Appendix B.1. This list is termed Base List 1 in EPRI 1025286. The five sample selection attributes, described in Section 3.2, were then applied to Base List 1. The results are summarized for each attribute below:

1. A variety of types of systems. Sample items were selected to represent a broad range of frontline and support systems. The number of selected items associated with each of the represented systems is provided in Appendix B.2 in the SWEL System Summary Table.

2. Mamor new and replacement equipment (since the completion of IPEEE/USI A-46 evaluations). This attribute is not applicable because no previous seismic walkdowns or evaluations were performed at MPS Unit 3 in response to USI A-46 or IPEEE requirements.

3. A variety of types of equipment. At least one item from each of the classes of equipment listed in EPRI 1025286, Appendix B: Classes of Equipment was included in SWEL 1 to provide a sample selection of a variety of equipment types. The number of items from each of the equipment classes is identified in Appendix B.2 in the SWEL Equipment Classes Summary Table. As described in Section 3.2, where there was no seismic category I equipment on Base List 1 for a specific class of equipment, no items in that equipment class were selected for SWEL 1. There were no items for equipment classes 12 and 13 on Base List 1, and the equipment class 19 items (temperature sensors) are inspected as part of other component assemblies. Therefore, no equipment from these three equipment classes was included in SWEL 1.

4. A variety of environments. Sample items were selected from different locations in the plant to include various environments (hot, cold, dry, wet). The installed location is identified on the SWEL in Appendix B.2 for each item, which provides an indication of the operating environment for the item.

5. Equipment enhanced due to vulnerabilities identified during the IPEEE program.

Based on a review of IPEEE documentation (References 7 and 8), no equipment enhancements were required due to IPEEE seismic vulnerabilities. 3-3

Millstone Power Station Unit 3 NTTF 2.3 Seismic Walkdown Summary Report The resulting sample of equipment for the SWEL 1 list was 98 items, which are provided in Appendix B.2. For each item on the list, the applicable supported safety function(s), listed below, were indicated.

Reactor reactivity control
Reactor coolant pressure control

 "    Reactor coolant inventory control

Decay heat removal

 "    Containment function SWEL 2 SWEL 2 was developed based on a review of systems associated with the spent fuel pool (SFP) that are Seismic Category I or components whose failure could result in a rapid drain-down of the water in the SFP to less than ten feet above the top of the fuel. The review was supported by a licensed operator and knowledgeable system engineers.

The following Seismic Category I system associated with the SFP was identified:

Spent Fuel Pool Cooling and Purification System Base List 2, resulting from applying EPRI 1025286 Figure 1-2 screening criteria 1 and 2 to the Spent Fuel Pool Cooling and Purification System equipment list, is provided in Appendix B.2.

The following components have been identified as the SWEL 2 list using the walkdown item sample selection criteria consistent with the guidance in EPRI 1025286:

   -    M33SFC*P1A Spent Fuel Pool Cooling Pump A
   -    M33SFC*E1A Spent Fuel Pool Heat Exchanger A Rapid Drain-down The Spent Fuel Pool Cooling and Purification system piping penetrates the SFP liner at an elevation just below the normal operating level of 49' 10". The piping configuration precludes SFP drain down by the use of piping anti-siphon features at elevations 45', 48', and 50'8". The top of the fuel assemblies is at 25' 9" elevation. FSAR Section 9.1 states that the MPS Unit 3 SFP configuration of piping elevations and anti-siphoning devices prevents siphoning of fuel pool water.

Therefore, there are no components that could, upon failure, result in rapid drain-down of the SFP water level to below ten feet above the top of the fuel and no components have been added to SWEL 2 for this criterion. SWEL The SWEL was developed by combining the items on SWEL 1 and SWEL 2. The SWEL is provided in Appendix B.2. All items on the list are from SWEL 1 except those items indicated by footnote as originating from SWEL 2. 3-4

Millstone Power Station Unit 3 NTTF 2.3 Seismic Walkdown Summary Report The items on the SWEL were reviewed to identify those that included anchorage (i.e., items that were not line-mounted equipment, such as valves). 63 items of the 68 items that included anchorage (92%) were selected for confirmation that the as-installed equipment anchorage is consistent with plant documentation of the anchorage design. The anchorage items selected for confirmation are indicated by a note on the SWEL. In addition, risk significant items on SWEL 1 were identified. This information was reviewed by the PRA subject matter expert as confirmation that risk insights were adequately considered in the development of the SWEL. As a result, 62 of the 100 items on the SWEL were identified as being risk significant. This list is the input to the seismic walkdowns conducted in accordance with EPRI 1025286, Section 4 Seismic Walkdowns and Area Walk-Bys. Walk-by areas were identified to include all of the items on the SWEL and are listed in Appendix B.3. 3.4 Inaccessible Items In the process of selecting SSCs to be included on the SWEL, items that were accessible and have visible anchorage were selected wherever possible. However, there were 24 items included on the SWEL that were not sufficiently accessible to complete the walkdown inspection. These items are listed in Table 3-1 'below and indicated by a footnote on the SWEL (Appendix B.2). The walkdowns for these items are planned to be completed by the end of the next scheduled refueling outage (Spring 2013). 3-5

Millstone Power Station Unit 3 NTTF 2.3 Seismic Walkdown Summary Report 4.0 Seismic Walkdowns and Area Walk-Bys The seismic walkdowns and area walk-bys were performed consistent with the guidance provided in the EPRI 1025286 (Reference 2). A site-specific procedure was developed to implement the EPRI 1025286 seismic walkdown guidance for conducting and documenting the seismic walkdowns. A walkdown package was prepared for each component listed on the SWEL and for each area walk-by to be performed. Each package included a seismic walkdown checklist (SWC) or an area walk-by checklist (AWC) and the drawing(s) showing equipment location, plant documentation showing the anchorage details for each SWEL item requiring anchorage configuration verification. A hardcopy of the package was available for the SWEs during performance of the equipment walkdown or area walk-by. The seismic walkdowns and area walk-bys were performed by walkdown teams, which consisted of at least two (2) qualified SWEs. For the seismic walkdowns, the SWEs focused on the following adverse seismic conditions associated with each item of equipment as described in the EPRI 1025286 guidance:

   " adverse anchorage conditions,
   " adverse seismic spatial interactions, and

other adverse seismic conditions The purpose of the area walk-bys was to identify potentially adverse seismic conditions associated with other SSCs located in the vicinity of the SWEL items. For the area walk-bys, SWEs focused on the following potentially adverse seismic conditions as described in the EPRI 1025286 guidance:

   " anchorage conditions (ifvisible without opening equipment),

significantly degraded equipment in the area,
condition of cable/conduit raceways, including condition of supports or fill conditions, and HVAC ducting,

   " potential adverse seismic interactions including those that could cause flooding, spray, or a fire in the area, and

housekeeping items that could cause adverse seismic interactions.

During the walkdown or walk-by, the walkdown teams discussed conditions and/or any findings in the field, reached agreement on the results of the walkdown, and documented results of the seismic walkdowns and area walk-bys on the checklists. The results of' the completed seismic walkdowns are documented on SWCs, which are included as Appendix C. The results of the completed area walk-bys are documented on AWCs, which are included as Appendix D. The SWEL includes 100 items to be walked down and 32 area walk-bys are defined. Of these, 76 walkdowns and 29 area walk-bys have been completed. The remaining items, 24 walkdowns and 3 area walk-bys, have been deferred because the component or area was not sufficiently accessible to complete the walkdown inspection and walkdown checklists are not included in this report for those items. The schedule for performance of these deferred seismic walkdowns is described in Section 3.4. 4-1

Millstone Power Station Unit 3 NTTF 2.3 Seismic Walkdown Summary Report Table 4-1 lists potentially adverse seismic conditions identified during the completed seismic walkdowns and area walk-bys. The items listed in Table 4-1 were submitted as Condition Reports (CRs) in the plant corrective action program (CAP). Table 4-1 summarizes the potentially adverse seismic conditions, describes how the condition has been addressed, and provides the current status of the resolution. A low threshold was used to identify and document potential adverse conditions. In addition to items listed in Table 4-1, non-seismic related potentially adverse conditions such as various housekeeping and material condition items, were identified by the walkdown teams and addressed through the CAP. No significant issues that challenged the MPS Unit 3 seismic licensing or design basis were identified as a result of the walkdowns completed to date. As indicated in Table 4-1, no planned or newly installed changes to the plant are required to resolve the items identified during the walkdowns. 4-2

Millstone Power Station Unit 3 NTTF 2.3 Seismic Walkdown Summary Report 6.0 IPEEE Vulnerabilities On June 28, 1991, the NRC issued Generic Letter (GL) 88-20, Supplement 4 (with NUREG-1407, Proceduraland Submittal Guidance) requesting each licensee to perform an individual plant examination of external events (IPEEE) to identify plant-specific severe accident vulnerabilities and to report the results to the Commission together with any licensee-determined improvements and corrective actions. The MPS Unit 3 response to GL 88-20, Supplement 4, was submitted to NRC in a letter dated December 23, 1991 (Reference 7). The Reference 7 letter referenced the Individual Plant Examination (IPE) Summary Report submittal dated August 31, 1990 (Reference 8) to fulfill the intent of GL 88-20, Supplement 4. The IPE was based on the updated MPS Unit 3 Probabilistic Safety Study, which was initially performed at initial plant operation. MPS Unit 3, which began commercial operation in 1986, was determined to be a high seismic margin plant. Although not identified as IPEEE vulnerabilities or outliers, the IPE Report (Reference 8), Table 6-2, Addressment of Significant PRA Findings, provides the seismic-related findings along with a description of how the items were addressed. The seismic related items are complete as indicated in Table 6-2 of the IPE Report. NRC letter dated May 26, 1998 (Reference 9) provides the NRC staff's evaluation of the Millstone Unit 3 IPEEE submittal and concludes that the intent of GL 88-20 Supplement 4 was met. 6-1

Leo Nadeau, Bechtel Power A summary of the results of the Peer Review is provided below:

1. Selection of SSCs The Peer Review Team performed a comprehensive review of the SWNEL. The SWEL was compared to the requirements of EPRI 1025286, Section 3, Selection of SSC utilizing Appendix F, Peer Review Checklist and was found to appropriately apply the EPRI 1025286 guidance including:

Selection of SWEL 1 SSCs
Use of sample selection attributes
Adequate representation of the five safety functions
Consideration of risk insights
Selection of spent fuel pool related items All peer review comments were minor and were adequately resolved.

2. Sample of Seismic Walkdown Checklist (SWC) and Area Walkdown Checklist (AWC)

The Peer Review Team reviewed a sample of walkdown results and concluded that the SWCs and AWCs were completed in accordance with the EPRI 1025286 guidance.

a. Packages - The Peer Review Team reviewed a sample of the seismic walkdown documentation packages prepared before walkdowns were performed. These walkdown packages were reviewed to ensure the seismic walkdown checklist and related documentation (e.g., walkdown checklist, anchorage details drawings, etc.)

were included. The packages were determined to be adequate to support the walkdowns.

b. SWC/AWC - There are 100 SWCs. 33 SWCs were peer reviewed representing 33% of the total, which exceeds the EPRI 1025286 requirement for a 10 - 25 %

sample. 17 AWCs from a total of 32 were peer reviewed representing 53% of the 7-1

Millstone Power Station Unit 3 NTTF 2.3 Seismic Walkdown Summary Report total. Overall, the SWC and AWC were determined to be appropriately detailed and complete.

c. Seismic Walkdown Engineers (SWEs) were interviewed by the Peer Review Team Lead to verify that they understood and followed the Guidance in EPRI 1025286, Section 4, Seismic Walkdowns and Area Walk-Bys. Results of the interviews indicated that each team understood and followed the EPRI guidance.

All peer review comments were minor and were adequately resolved.

3. Review of Licensing Basis Evaluations All potentially adverse seismic conditions identified during the walkdowns were entered into the CAP consistent with plant procedure. There were no Licensing Basis Evaluations, as defined in EPRI 1025286, performed that were in addition to the CAP reviews.

4. Review of Conditions Entered into CAP The threshold level at which field-identified conditions were entered in CAP was considered to be appropriate to ensure that potential licensing basis issues were documented and reviewed by Engineering and the Operations Shift Manager for operability concerns. Appropriate functional organizations (e.g., Operations, Maintenance, and Site Engineering) were routinely consulted and engaged in the evaluation of potentially adverse seismic conditions.

5. Review of Submittal Report A review of the submittal report was performed by members of the Peer Review Team and it was determined that the objectives and requirements of the 50.54(f) Letter were met.
