Engineering Report No. VY-RPT-12-00019 Rev. 0 Page 3 of 28 1.0 SCOPE AND OBJECTIVE The Great Tohoku Earthquake of March 11, 2011 and the resulting tsunami caused an accident at the Fukushima Dai-ichi nuclear power plant in Japan' In response to this accident, the Nuclear Regulatory Commission (NRC) established the Near-Term Task Force (NTTF), tasked with conducting a systematic and methodical review of NRC processes and regulations and determining if the agency should make additional improvements to its regulatory system. On March 12, 2012 the NRC issued a 10CFR50.54(f) letter (Ref. 10.1) requesting information from all licensees to support the NRC staff's evaluation of several of the NTTF recommendations. To support NTTF 2.3, Enclosure 3 to the 50.54(f) letter requested that all licensees perform seismic walkdowns to gather and report information from the plant related to degraded, non-conforming, or unanalyzed conditions with respect to its current seismic licensing basis.

The Electric Power Research Institute (EPRI), with support and direction from the Nuclear Energy Institute (NEI), published industry guidance for conducting and documenting the seismic walkdowns which represented the results of extensive interaction between NRC, NEI, and other stakeholders. This industry guidance document, EPRI Report 1025286 (Ref. 10.2), hereafter referred to as "the Guidance,"

was formally endorsed by the NRC on May 31, 2012. Entergy Vermont Yankee Nuclear Power Station (VYNPS) has committed to using this NRC-endorsed guidance as the basis for conducting and documenting seismic walkdowns for resolution of NTTF Recommendation 2.3: Seismic.

The objective of this report is to document the results of the seismic walkdown effort undertaken for resolution of the Fukushima Near Term Task Force (NTTF) Recommendation 2.3, Seismic.

This report summarizes the basis, planning, preparation, execution and findings of the seismic walkdowns and constitutes the "Submittal Report" as described in Section 8 of the Guidance dated June 2012. The objective of the walkdown effort was to provide responses to the 10 CFR 50.54(f) letter issued by the NRC on 3/12/12 (Ref. 10.1). This included walkdowns of a sample of components and walk-bys of associated areas of the plant to identify potentially adverse seismic conditions within the parameters provided in EPRI Report 1025286 (Ref. 10.2). Adverse seismic conditions included those that could, due to a seismic event:

• interfere with/prevent the proper functioning of the subject component

" create the possibility of flood of the subject area

" potentially cause spray on equipment

" potentially cause/enable fires in the subject area and

• cause unanticipated, rapid drain down of the spent fuel pool(s)

A sample population of components for inspection was developed as discussed in Section 6.0. This component sample constituted the Seismic Walkdown Equipment List (SWEL) which satisfies the requirements for sampling as outlined in EPRI Report 1025286.

Using the SWEL, walkdown teams consisting of two Seismic Walkdown Engineers (SWEs) per team walked down the subject components. Results of the walkdowns were recorded on Seismic Walkdown Checklists (SWCs). All accessible items on the SWEL were walked down. Inaccessible items are listed in Section 6.4 and will be walked down when the specific equipment or area is operationally accessible. In addition, an area walk-by (AWB) was performed for each room/area of the plant containing a component listed in the SWEL. Results of the area walk-bys were recorded on Area Walk-by Checklists (AWCs).

Engineering Report No. VY-RPT- 12-00019 Rev. 0 f Page 4 of 28 Area Walk-bys supplemented the seismic walkdowns and provided for inspections of general areas in the vicinities of the subject equipment. This eliminated tunnel-vision and allowed a vehicle to report other potentially adverse conditions. In cases where multiple SWEL items were located in the same room/area of the plant, a single AWB was conducted. Plant rooms/areas were generally found to be sufficiently compact to allow for robust AWBs under these conditions. In the cases where a component was located in a very large area/room, the walk-by was limited to an area with a radius of approximately 35 feet around the component on the SWEL. The limits of the walk-by for these cases are defined on the Area Walk-by Checklist.

The intent of the walkdowns/walk-bys was to identify potentially adverse seismic conditions with a focus on anchorage and seismic spatial interactions. Potentially adverse seismic conditions were noted on the SWCs and AWCs, and were ultimately entered into the plant's Corrective Action Program (CAP) for documentation, evaluation and resolution.

Results of the component walkdowns and area walk-bys are discussed and summarized in Section 7.0.

Copies of the walkdown and walk-by checklists are provided in Attachments C and D.

Section 8.0 contains a discussion of potentially adverse seismic conditions identified during the field inspections. A list of potentially adverse seismic conditions is provided in Attachment E.

Licensing basis evaluations (LBEs) were performed as part of the resolution of the CRs that were initiated to document potentially adverse seismic conditions. The results of the LBEs are discussed in Section 8.0 and additional information is provided in Attachment F.

2.0 SEISMIC LICENSING BASIS

SUMMARY

Vermont Yankee Nuclear Power Station (VYNPS) is a boiling water reactor (BWR) located in Vernon, Vermont. The Nuclear Steam Supply System (NSSS) was originally designed by GE and VYNPS began commercial operation in November of 1972, and is currently rated at 1912 MWt power. This section summarizes the seismic licensing basis of structures, systems and components (SSCs) at VYNPS which bound the context of the NTTF 2.3 Seismic Walkdown program.

2.1 Safe Shutdown Earthquake In accordance with Draft Criterion 2, "Design Bases for Protection Against Natural Phenomena", of 10 CFR 50, Appendix A, structures, systems, and components important to safety are designed to withstand the effects of natural phenomena such as earthquakes without loss of the capability to perform those safety functions necessary to cope with appropriate margin to account for uncertainties in the historical data. Appendix C of the original Final Safety Analysis Report (FSAR) documents that the plant satisfies the earthquake principal design criteria described in draft AEC Criterion 2.

The Safe Shutdown Earthquake (SSE) for VYNPS is based on a recurrence of the largest historical earthquake in the region applied at the closest known location of faulting. It is specifically characterized by a Housner spectral shape anchored at 0. 14g (SSE) peak horizontal ground acceleration with vertical accelerations equal to 2/3 of the horizontal ground acceleration (Ref. 10. 14).

The damping factors used in the dynamic seismic analysis are given in the Updated Final Safety Analysis Report (UFSAR).

Engineering Report No. VY-RPT-12-00019 Rev. 0 Page 5 of 28 Additionally, the UFSAR Section 1.6.1.1.7 states:

"Based on a three-fold seismic evaluation, the site was found to be relatively quiescent from a seismic standpoint. From these studies the design earthquake has been established at 0.07g horizontal ground acceleration and the maximum hypothetical earthquake at 0.14g horizontal ground acceleration. The seismic evaluation consisted of a review of historical data from the New England area, an analysis of instrument and historical records for the Vermont area, and a study of earthquake intensity attenuation with distance for the northeast United States."

2.2 Design Codes, Standards and Methods Seismic Input to Structures and Equipment:

VYNPS was designed to withstand the effects of seismic events applicable to Class I systems.

The Updated Final Safety Analysis Report (UFSAR) (Ref. 10.14) describes Class I SSCs as those structures, equipment, and components whose failure or malfunction might cause or increase the severity of an accident which would endanger the public health and safety. This category includes those structures, equipment, and components required for safe shutdown and isolation of the reactor. Both the vertical and either of the responses- of the two horizontal seismic motions are considered to be applied simultaneously and in combination with all other applicable design loads. The larger combination controls the design.

Structures, Equipment and Components:,

Seismic Class I structures applicable to the scope of the NTTF 2.3 Seismic Walkdown Program include the Reactor Building, Control Building, Intake Structure and Emergency Diesel Generator Rooms including day tank enclosures located in the Turbine Building. Seismic design of Class I SSCs is in accordance with Section 12.2 of the UFSAR and Topical Design Basis Document for External Events (Ref 10.15).

Class I equipment analysis considers vertical and horizontal ground motions. The horizontal motion accounts for the equipment elevation above grade and also considers the stiffness of equipment supports. Appendix C to the UFSAR provides the Seismic Class I criteria for equipment and piping design. Appendix A to the UFSAR provides the description, scope and design methodologies for Class I piping systems.

Methodology based on earthquake experience data developed by the Seismic Qualification Utility Group (SQUG) and documented in the Generic Implementation Procedure (GIP),

Revision 2, plus any addition to the GIP reviewed and accepted by the NRC for resolving Unresolved Safety Issue (USI) A-46 in response to NRC Generic Letter 87-02, was used to verify the seismic adequacy of equipment included within the scope USI A-46.

An extensive list of design codes, standards, methods, studies and tests utilized for seismic design is provided in the VYNPS UFSAR. A summary of the more relevant references for the design of Seismic Category I structures, systems and components is provided here.

Entergy developed procedure EN-DC-168, "Fukushima Near-Term Task Force Recommendation 2.3 Seismic Walk-down Procedure" (Ref. 10.13), outlining the guidelines, processes and required documentation generated during the walkdowns. The approach provided in the guidance for addressing the actions and information requested in Enclosure 3 to the 50.54(f) letter includes the following activities, the results of which are presented in the sections shown in parenthesis:

• Assignment of appropriately qualified personnel (Section 4.0)

• Reporting of actions taken to reduce or eliminate the seismic vulnerabilities identified by the Individual Plant Examination of External Events (IPEEE) program (Section 5.0)

" Selection of structures, systems and components (SSCs) to be evaluated (Section 6.0)

" Performance of the seismic walkdowns and area walk-bys (Section 7.0)

• Evaluation and treatment of potentially adverse seismic conditions with respect to the seismic licensing basis of the plant (Section 8.0)

" Performance of peer reviews (Section 9.0)

The coordination and conduct of these activities was initiated and tracked by Entergy corporate leadership, which provided guidance to each Entergy site throughout the seismic walkdown program, including VYNPS. Entergy contracted with an outside nuclear services company to provide engineering and project management resources to supplement and assist each individual site. VYNPS had dedicated engineering contractors, supported by their own project management and technical oversight, who worked closely with plant personnel.

5.0 IPEEE VULNERABILITIES REPORTING During the IPEEE program in response to NRC Generic Letter 88-20 (Ref. 10.3), plant-specific seismic vulnerabilities were identified at many plants. In this context, "vulnerabilities" refers to conditions found during the IPEEE program related to seismic anomalies, outliers, or other findings.

The IPEEE final report (Ref. 10.10) and supporting documentation was reviewed to identify items determined to present a seismic vulnerability. The IPEEE Reviewers then reviewed additional plant documentation to identify the eventual resolutions to those seismic vulnerabilities not resolved when the IPEEE report was submitted.

The seismic vulnerabilities identified for VYNPS during the IPEEE program are reported in Attachment A. A total of five seismic vulnerabilities were identified by the VYNPS IPEEE program.

For each identified seismic vulnerability, the table in Attachment A includes three pieces of information requested by Enclosure 3 of the 50.54(f) Letter:

• A description of the action taken to eliminate or reduce the seismic vulnerability

• Whether the configuration management program has maintained the IPEEE action (including procedural changes) such that the vulnerability continues to be addressed

• When the resolution actions were completed.

The list of IPEEE vulnerabilities provided in Attachment A was used to ensure that some equipment enhanced as a result of the IPEEE program were included in SWEL 1. Documents describing these equipment enhancements and other modifications initiated by identification of IPEEE vulnerabilities were available and provided to the SWEs during the NTTF 2.3 Seismic Walkdowns.

6.0 SEISMIC WALKDOWN EQUIPMENT LIST DEVELOPMENT This section summarizes the process used to select the SSCs that were included in the Seismic Walkdown Equipment List (SWEL) in accordance with Section 3 of the Guidance. A team of equipment selection personnel with extensive knowledge of plant systems and components was selected to develop the SWEL. The SWEL is comprised of two groups of items:

Engineering Report No. VY-RPT-12-00019 Rev. 0 Page 13 of 28

" SWEL 1 consists of a sample of equipment required for safe shutdown of the reactor and to maintain containment integrity (i.e., supporting the five safety functions) .

• SWEL 2 consists of items related to the safety related spent fuel pool system The final SWEL is the combination of SWEL 1 and SWEL 2. The development of these two groups is described in the following sections.

Sample of Required Items For The Five Safety Functions Safe shutdown of the reactor involves four safety functions:

• Reactor reactivity control (RRC)

• Reactor coolant pressure control (RCPC)

• Reactor coolant inventory control (RCIC)

• Decay heat removal (DHR)

Maintaining containment integrity is the fifth safety function:

• Containment function (CF)

The overall process for developing a sample of equipment to support these five safety functions is summarized in Figure 1-1 of the Guidance. Figure 1-1 of the Guidance provides a screening method for selecting SSCs, starting with all of the plant SSCs and reducing the number based on a series of screening criteria. The equipment coming out of Screen #3 and entering Screen #4 is defined as Base List 1. The equipment coming out of Screen #4 is the first Seismic Walkdown Equipment List, or SWEL 1. Development of these lists is described separately in the following sections:

6.1 Base List A spreadsheet was developed to tabulate the total number of equipment for each of the twenty two (22) GIP equipment classes. The total equipment number was approximately 750 items.

The target number of equipment for the SWEL 1 list is approximately 100 to 110 items.

Therefore, approximately 15 % of the original A46/IPEEE equipment will be used to develop the SWEL 1 list to perform seismic verification of the equipment.

Based on Figure 1-1 and Section 3 of the Guidance, Base List 1 should represent a set of Seismic Category (SC) I equipment or systems that support the five safety functions. The IPEEE program was intended to address the seismic margin of SSCs associated with each of the five safety functions. At Vermont Yankee Nuclear Station, the EPRI Seismic Margin Assessment (EPRI SMA) method was used to complete the seismic IPEEE program, based on EPRI Report NP-6041 titled "A Methodology for assessment of Nuclear Power Plant Seismic Margin." As described in Section 3.2.2.1 of the Vermont Yankee Nuclear Station IPEEE report (Ref. 10.10), an equipment list was developed representing the SSCs necessary for one preferred and one alternate "success path" capable of achieving and maintaining a safe shutdown condition for at least seventy-two hours following a SSE event. This equipment list of SSCs on the success paths is consistent with the requirements of Screens #1 through #3 of the Guidance. Therefore, the IPEEE equipment list of SSCs on the success paths is used as a starting point for the NTTF 2.3 Seismic Walkdown Base List 1.

Base List 1 is presented in Table 9.4.1 of Attachment B, and has 736 total items.

Engineering Report No. VY-RPT- 12-00019 Rev. 0 Page 14 of 28 6.2 SWEL 1 Based on the target of 105 items, each equipment class total was factored down by 15% to obtain an idealized number of equipment in each equipment class to be selected to maintain the same equipment diversity as the original A46/IPEEE equipment list.

In parallel with the above, a risk ranking assessment was performed to determine the most risk significant equipment from the A46/IPEEE list. This assessment method (see Attachment J) resulted in the assignment of risk value to A46/IPEEE SSEL equipment. The equipment was sorted to identify all equipment that exceeded a pre-determined risk threshold.

The above equipment sort for equipment risk ranking fulfills the risk ranking requirement shown in Reference 10.2, Figure 1-1 graphic that defines the process to develop the SWEL 1 list. This risk ranking fulfills the requirement to select equipment that supports the 5 required safety functions The resultant risk ranking listing contained redundant trains of multiple systems. Each equipment type on the risk ranking list was selected to cover the maximum amount of building areas where the system are located. For example, both A & B EDG components were selected to cover all areas of each room and any unique features such as the EDG B penthouse louvers located on the roof of the EDG B room. The RHR equipment in the corner rooms of the Reactor Building was selected to minimize dose exposure for the walkdown personnel and have equipment on each level of each corner room. Once the risk significant equipment was represented the "Sample Considerations screen was applied. Throughout the application of this screen, dose surveys for the equipment areas were reviewed to ensure equipment in the lower dose areas were selected if there was an option.

During application of the above screens the overall GIP equipment class percentages were maintained to ensure equipment diversity and representation of the makeup of the original A46/

IPEEE equipment list.

Equipment with anchorage modifications as a result of the A46/IPEEE programs were selected whenever possible to complete the target number in each equipment classification. These modifications were designed to IPEEE seismic levels and thereby are considered an IPEEE enhancement. In addition, two new components were added that were not on the original A46/IPEEE lists. One component is a new inverter that replaces a battery & charger system and the other is a new nitrogen bottle system used to support Safety Relief Valve (SRV) actuation from outside the primary containment. Equipment was also selected to ensure adequate representation from various environments. Specifically, Based on Figure 1-1 and Section 3 of the Guidance, SWEL 1 should represent a diverse population of items on Base List 1 including representative items from some of the variations within each of five sample selection attributes.

Additionally, the selection of SWEL 1 items includes consideration of the importance of the contribution to risk for the SSCs. Equipment Selection Personnel developed SWEL 1 using an iterative process. The following paragraphs describe how the equipment selected for inclusion on the final SWEL 1 are representative with respect to each of the five sample selection attributes while also considering risk significance. In general, preference for inclusion on SWEL 1 was given to items that are accessible and have visible anchorage while still maintaining the sample selection attributes.

Engineering Report No. VY-RPT- 12-00019 Rev. 0 Page 15 of 28 SWEL 1 is presented as Table 9.4.2 in Attachment B, and has 102 total items.

Variety of Types of Systems Items were selected from Base List 1. ensuring that each of the five safety functions was well represented. Additionally, components from a variety of frontline and support systems, as listed in Appendix E of the Guidance, were selected. The system type of each item on SWEL 1 is listed on Table 9.4.2 of Attachment B.

Major New and Replacement Equipment With. assistance from Plant Operations, Equipment Selection Personnel identified items on Base List 1 which are either major new or replacement equipment installed within the past 15 years, or have been modified or upgraded recently. These items are designated as such on Base List 1 in Table 9.4.1 of Attachment B. A robust sampling of these items is represented on SWEL 1.

Variety of Equipment Types According to Appendix B of the Guidance, there are 22 classes of mechanical and electrical equipment. The items on Base List 1 were classified accordingly and the total number from each class was determined. Items were then selected from Base List 1 ensuring that each of the equipment classes represented there was also represented on SWEL 1 in approximately the same ratios. The equipment class of each -item on SWEL 1 is listed on Table 9.4.2 of Attachment B.

Variety of Environments Items were selected from Base List 1 located in a variety of buildings, rooms, and elevations.

These item locations included environments that were both inside and outside, as well as having high temperature and/or elevated humidity and within containment. The location and environment of each item on SWEL 1 is listed on Table 9.4.2 of Attachment B.

IPEEE Enhancements With assistance from IPEEE Reviewers, Equipment Selection Personnel identified items on Base List 1 which were enhanced as a result of seismic vulnerabilities identified during the IPEEE program. These items are designated as such on Base List 1 in Table 9.4.1 of Attachment B. Several of these items are represented on SWEL 1.

Risk Significance Information from the plant Probabilistic Risk Analysis (PRA) model was used to determine whether items were risk significant (see Attachment J for details). Where otherwise comparable items could be chosen relative to the sample selection attributes, the item with higher risk significance was chosen.

Engineering Report No. VY-RPT- 12-00019 Rev. 0 Page 16 of 28 6.3 Spent Fuel Pool Items The overall process for developing a sample of SSCs associated with the spent fuel pool (SFP) is similar to that of the screening process for SWEL 1 and is summarized in Figure 1-2 of the Guidance. The equipment coming out of Screen #2 and entering Screen #3 is defined as Base List 2. The items coming out of Screen #4 are the items that could potentially cause the SFP to drain rapidly. The items coming out of either Screen #3 or Screen #4 are the second Seismic Walkdown Equipment List, or SWEL 2. Development of these lists is described separately in the following sections.

The process for selecting spent fuel pool related items is illustrated in Figure 1-2 of Reference 10.2. This process produces the second Seismic Walkdown Equipment List (SWEL 2).

6.3.1 Base List 2 The following drawings were reviewed to determine the scope of systems and equipment associated with the SWEL 2 development:

G-191173 Sheet 1, Rev. 40, "Flow Diagram Fuel Pool Cooling & Clean Up System" G-191173 Sheet 2, Rev. 10, "Flow Diagram Fuel Pool Cooling & Clean Up System" G- 191218, Rev. 12, "Reactor Fuel Storage Pool Piping Plan" 5920-00280, Rev. 11, "Arrangement Refueling Facilities" G-191688, Rev. 10, "Reactor Building Pool Liner & Gates - SH 1" G-191689, Rev. 7, "Reactor Building Pool Liner & Gates - SH 2" G-191690, Rev. 3, "Reactor Building Pool Liner & Gates - SH 3" G-191691, Rev. 9, "Reactor Building Pool Liner & Gates - SH 4" 5920-06889, Sheet I of 3, "Fuel Storage Rack Arrays - Sheet 1" Base List 2 is presented in Table 9.4.3 of Attachment B.

6.3.2 Rapid Drain Down A review of spent fuel pool drawings was performed to assess any potential rapid drain down paths. One determination was to review these drawings to identify any Spent Fuel Pool (SFP) penetrations below about 10 feet above the top of fuel assemblies. The result of the review confirmed there are no penetrations meeting the above criteria in the SFP.

It was noted that during refueling operations when the SFP is communicating with the flooded reactor cavity there is a potential drain path from the reactor cavity drain lines.

Yankee Atomic Electric Company (YAEC) Report #1493, "Vermont Yankee Nuclear Power Plant Evaluation of Potential Failures of the Spent Fuel Pool Storage System", was prepared in response to IE Bulletin 84-03, "Refueling Cavity Water Seal". This report evaluates the potential for, and consequences of, a cavity seal failure. It considered the potential drain paths through attached piping for the fuel pool, refueling cavity and dryer separator storage pit. The

Engineering Report No. VY-RPT-12-00019 Rev. 0 Page 17 of 28 "Seismic Event" section evaluates this piping. The seismic piping is concluded to be adequate and the failure of the non-seismic piping is considered a "very unlikely scenario and conservative assumption". The postulated failure of all non-seismic drain lines was addressed by evaluating inventory loss rate and available makeup source rates. It was concluded this connected piping failure would drain the top 6 feet of the SPF in 54 minutes with no Operator action and the makeup capacity exceeds the leak rate capacity 6.3.3 SWEL 2 The first screen of Seismic Category I (SCI) equipment limits the scope to the Standby Fuel Pool Cooling System and associated SCI support equipment. A review of G-191173 flow diagrams provided the source for the identification of SCI equipment. Using sampling considerations defined in Reference 10.2, the resulting equipment is a pump, valve, heat exchanger, control panel and instrument rack and associated indicating instruments. A total of eleven (11) components were selected. SWEL 2 is presented in Table 9.4.5 of Attachment B.

6.4 Deferred, Inaccessible Items on SWEL Each item on the SWEL shall be walked down as part of the NTTF 2.3 Seismic Walkdown program. In order to perform the seismic walkdowns of these items, it is necessary to have access to them and to be able to view their anchorage. In some cases, it was not feasible to gain access to the equipment or view its anchorage because Vermont Yankee Nuclear Station was at power during the entire 180-day response period of Enclosure 3 to the 50.54(f) letter. For these cases, walkdowns of these items have been deferred until the next refueling outage (RFO 30) in March of 2013. An updated submittal report incorporating these deferred walkdowns will be provided within 90 days from the end of RFO 30.

Deferred items are summarized in the table below. A total of 13 items are deferred due to lack of access (high radiation areas). Eight (8) items are in the Steam Tunnel and five (5) items are in the Drywell.

These activities were conducted at VYNPS by teams of two, trained and qualified Seismic Walkdown Engineers (SWEs) (see Section 4.0). Each team included one engineer with at least several years of experience in seismic design and qualification of power plant SSCs. A total of three SWE teams were used. Each walkdown team was accompanied by at least one plant representative to assure personnel and equipment safety, and support maximum application of ALARA principles.

The seismic walkdowns and area walk-bys were conducted over the course of 3 weeks during October of 2012. Each morning, a pre-job brief with all personnel involved was conducted. This pre-job brief was used to outline the components and areas that would be walked down that day, to ensure consistency between the teams, to reinforce expectations, to identifying potential personnel safety issues specific to that day, and to allow team members to ask questions and share lessons learned in the field. The SWE teams brought cameras, tape measures, flashlights and, mirrors, as well as the required forms and supporting drawings into the field to assist with the seismic walkdowns and area walk-bys.

7.1 Seismic Walkdowns Seismic walkdowns were performed in accordance with Section 4 of the Guidance for all items on the SWEL (SWEL 1 plus SWEL 2), except for those determined to be inaccessible and deferred. To document the results of the walkdown, a Seismic Walkdown Checklist (SWC) with the same content as that included in Appendix C of the Guidance was created for each item. Additionally, photographs were taken of each item and included on the corresponding SWC.

The SWE teams conducted preliminary "scouting" walkdowns to get a general understanding of plant layout and to identify items on the draft SWEL that were inaccessible. One item that was identified to be inaccessible on these "scouting" walkdowns was a valve covered in insulation. After discussion with the Equipment Selection Personnel, the valve was replaced with another valve in similar environment while ensuring that the overall integrity of the final SWEL was not compromised.

Prior to- performance of the walkdowns, documentation packages were developed that contained the pre-filled SWC and other pertinent information including the location drawings, response spectra information, previous A-46 and IPEEE seismic walkdown documentation, and anchorage drawings where applicable. These documentation packages were brought with the

Engineering Report No. VY-RPT- 12-00019 Rev. 0 Page 19 of 28 SWE teams into the plant during the seismic walkdowns.

Walkdown inspections focused on anchorages and seismic spatial interactions, but also included inspections for other potentially adverse seismic conditions. Anchorage, in all cases, was considered to specifically mean anchorage of the component to the structure. This included anchor bolts to concrete walls or floors, structural bolts to structural steel and welds to structural steel or embedded plates. For welds, the walkdown team looked for cracks and corrosion in the weld and base metal. Other bolts or connections, such as flange bolts on in-line components were not considered as equipment anchorage. These bolts and connections were evaluated by the SWEs and any potential adverse seismic concerns were documented under "other adverse seismic conditions" rather than under "anchorage". Thus, components with no attachments to the structure are considered as not having anchorage. Nevertheless, the attachment of these components to other equipment was evaluated and inspected for potentially adverse seismic conditions.-

Cabinets/panels on the SWEL that could be reasonably opened without presenting safety or operational hazards were opened during the walkdown. This allowed visual observation of internal anchorage to the structure (where present), as well as inspection for "other adverse seismic conditions" related to internal components if it could be observed without breaking the plane of the equipment being opened. Where opening the cabinet/panel required extensive disassembly (e.g., doors or panels were secured by more than latches, thumbscrews, or similar),

justification for how the inspection met the program goal without opening the cabinet/panel was included on the SWC and the walkdown of that item is considered complete.

In addition to the general inspection requirements, at least 50% of the SWEL items required confirmation that the anchorage configuration was consistent with plant documentation. Of the 100 SWEL items inspected, 53 anchorage inspections were conducted and documented which is greater than the 50% requirement. When anchorage configuration verification was conducted, the specific plant documentation used for comparison to the as-found conditions was referenced on the SWC.

The SWC for each SWEL item where a seismic walkdown has been initiated is included in Attachment C. A total of 100 SWCs are attached; 100 with completion status marked "Y" and 0 with completion status marked "N". Therefore, the 100 completed SWCs represent the completed walkdowns of each SWEL item accessible during the walkdown period.

A total of eighty-nine (89) items were walked down for SWEL 1 and eleven (11) for SWEL 2.

Thirty nine (39) Area Walk-By were also performed.

It should be noted that SWEL 1 contains 102 items with 13 out of the 102 items (8 in the Steam Tunnel and 5 in the Drywell) deferred to the next refueling outage due to access and ALARA considerations. Seven of these 13 deferred SWEL 1 items will include an anchorage configuration verification. There were no deferred items for SWEL 2.

Area Walk-Bys Seismic area walk-bys were performed in accordance with Section 4 of the Guidance for all plant areas containing items on the SWEL (SWEL 1 plus SWEL 2) except for those SWEL items located in plant areas inaccessible during the walkdown period. A separate Area Walk-

Engineering Report No. VY-RPT- 12-00019 Rev. 0 Page 20 of 28 By Checklist (AWC) with the same content as that included in Appendix C of the Guidance was used to document the results of each area walk-by performed. Photographs were taken of each area, and included on the corresponding SWC.

Area walk-bys were conducted once for plant areas containing more than one SWEL item. In cases where the room or area containing a component was very large, the extent of the area encompassed by the area walk-by was limited to a radius of approximately 35 ft. around the subject equipment. The extent of the areas included in the area walk-bys is described on the AWC for that area. Because certain areas contained more than one SWEL item, there are fewer total area walk-bys conducted than seismic walkdowns. A total of 39 area walk-bys were necessary to cover all plant areas containing at least one accessible SWEL item.

The AWC for each area walk-by completed is included in Attachment D. A total of 39 AWCs are attached, which represent all of the areas containing a SVWEL item that were accessible during the walkdown period. An additional 5 estimated area walk-bys of areas inside the Drywell and Steam Tunnel will be completed together with the deferred walkdowns for those inaccessible items.

8.0 LICENSING BASIS EVALUATIONS During the course of the seismic walkdowns and area walk-bys, the objective of the SWE teams was to identify existing degraded, non-conforming, or unanalyzed plant conditions with respect to its current seismic licensing basis. This section summarizes the process used to handle conditions identified, what conditions were found, and how they were treated for eventual resolution.

Condition Identification When an unusual condition was observed by a SWE team in the field, the condition was noted on the SWC or AWC form and briefly discussed between the two SWEs to agree upon whether it was a potentially adverse seismic condition. These initial conclusions were based on conservative engineering judgment and the training required for SWE qualification.

For conditions that were reasonably judged as insignificant to seismic response, the disposition was included on the SWC or AWC checklist and the appropriate question was marked "Y", indicating that no associated potentially adverse seismic condition was observed. Unusual or uncertain conditions were reported to site personnel for further resolution through the Corrective Action Program (CAP). A total of 131 seismically insignificant conditions were identified. These conditions were generally related to either housekeeping or minor non-consequential degradation. No seismically significant conditions were found.

Unusual conditions that were potentially seismically significant were entered into the CAP directly.

Further resolution of these conditions is not tracked or reported as part of the NTTF 2.3 Seismic Walkdown program, except by noting the CR numbers generated on the applicable SWCs and AWCs.

8.1 Licensing Basis Evaluations There were no Licensing Basis Evaluations required. All unusual conditions were entered into the CAP system immediately and dispositioned for operability, with no operability issues identified.

8.3 Plant Changes There are no changes required as a result of this effort.

9.0 PEER REVIEW This section summarizes the process and results of each peer review activity.

9.1 Peer Review Process The peer review for the NTTF Recommendation 2.3 Seismic Walkdowns was performed in accordance with Section 6 of the Guidance. The peer review included an evaluation of the following activities:

Engineering Report No. VY-RPT-12-00019 Rev. 0 Page 23 of 28

• 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 and area walk-bys;

" review of licensing basis evaluations and decisions for entering the potentially adverse conditions in to the plant's Corrective Action Plan (CAP); and

• review of the final submittal report.

At least two members of the peer review team (see Section 4.5) were involved in the peer review of each activity, the team member with the most relevant knowledge and experience taking the lead for that particular activity. A designated overall Peer Review Team Leader provided oversight related to the process and technical aspects of the peer review, paying special attention to the interface between peer review activities involving different members of the peer review team.

9.2 Peer Review Results Summary 9.2.1 Seismic Walkdown Equipment List Development The selection of items for the SWEL underwent peer review according to the guidance in Section 3 of the Guidance. The SSCs to be evaluated during the seismic walkdown were selected as described in Section 6.0. The list of components was provided to the members of the peer review team listed in Section 4.5. The peer review members independently provided comments to the personnel who selected the components. All comments were addressed and the peer review team reviewed the changes made to the SWEL and the final SWEL, to ensure all recommenditions from the Guidance were met. Specific considerations for the peer review process are described below for SWEL 1 and SWEL 2.

For SWEL 1, the peer review team verified that the list of SSCs represented a diverse sample of

.the equipment required to perform the following five safety functions, as specified in the Guidance:

• Reactor Reactivity Control;

• Reactor Coolant Pressure Control;

• Reactor Coolant Inventory Control;

• Decay Heat Removal; and

• Containment Function.

For SWEL 1, the peer review also verified that the SSCs included an appropriate representation of items having the following sample selection attributes:

• Various types of systems;

• Major new and replacement equipment;

• Various types of equipment;

• Various environments;

• Equipment enhanced based on the findings of the IPEEE; and

Engineering Report No. VY-RPT- 12-00019 Rev. 0 Page 24 of 28 Ilisk insight consideration.

The final SWEL 1 contains a number of items that perform each of the five safety functions specified in the Guidance. Numerous components perform more than one of the safety functions and all five safety functions are well represented by the components on the list.

SWEL 1 contains components from all the classes of equipment listed in Appendix B of the Guidance, except for cases where there are no Safety Related components at the plant that fall into that specific equipment class. The list contains major new and replacement items, and items enhanced based on the IPEEE as well as equipment located in various environments and areas of the plant. All major safety related systems are represented and risk factors were considered in development of the list.

For SWEL 2, the peer review team determined that the process to select spent fuel pool related items complied with the Guidance. Portions of the spent fuel pool cooling system at Vermont Yankee are safety related Seismic Category I and all different types of components associated with the safety-related system are represented on the SWEL 2. No items that could cause rapid drain down of the Spent Fuel Pool for Vermont Yankee were identified. Therefore, SWEL 2 does not contain any components associated with potential rapid drain down of the pool. The peer review team concluded that the bases for including/excluding items associated with the spent fuel pool were well documented and that the final SWEL 2 complies with the Guidance.

All of the peer review comments made during development of SWEL 1 and 2 were resolved by the team that prepared the SWELs. The resolutions were reviewed by the peer review team and it was determined that all comments were adequately addressed.

9.2.2 Seismic Walkdowns and Area Walk-Bys Peer review of the seismic walkdowns and area walk-bys was conducted by two peer reviewers, each of whom is a qualified SWE and has broad knowledge of seismic engineering applied to nuclear power plants. One of the peer reviewers participated in the seismic walkdown program for a different utility. The peer reviews were conducted at the VYNPS concurrent with the conduct of walkdowns, at approximately 50% completion. The peer review was performed as follows:

" The peer review team reviewed the walkdown packages (including checklists, photos, drawings, etc.) for SWEL items already completed to ensure that the checklists were completed in accordance with the Guidance. A total 19 SWC and 11 AWC forms were reviewed, each representing approximately 20% of their respective totals. In the context of the Guidance, the peer review team considered the number of walkdown packages reviewed to be appropriate. The packages reviewed represent a variety of equipment types in various plant areas. While reviewing the walkdown packages, the peer reviewers conducted informal interviews of the SWEs and asked clarifying questions to verify that they were conducting walkdowns and area walk-bys in accordance with the Guidance.

• The peer review team held a meeting with the SWE teams to provide feedback on the walkdown and walk-by packages reviewed and the informal interviews, and discuss potential modifications to the documentation packages in the context of the Guidance.

• Each peer reviewer accompanied each SWE team into the field and observed them perform a walkdown of a SWEL component and its associated area walk-by. During

Engineering Report No. VY-RPT- 12-00019 Rev. 0 Page 25 of 28 these observations, the peer reviewers asked clarifying questions to verify the walkdown and walk-by process being followed was in accordance with the Guidance.

The items walked down under the observation of a peer reviewer are listed below. The associated area walk-bys performed under the observation of a peer reviewer are listed below.

The peer review team held a meeting with the SWE teams to provide feedback on the walkdown and walk-by observations, and discuss how lessons learned from review of the walkdown packages had been incorporated into the walkdown process.

As a result of the peer review activities, the SWIE teams modified their documentation process to include additional clarifying details, particularly related to checklist questions marked "N/A" and where conditions were observed but judged as insignificant. The peer review team felt these modifications would be of benefit for future reviews of checklists incorporated into the final report. These modifications were recommended following review of the walkdown and area walk-by packages, and the observation walkdowns and area walk-bys demonstrated that the SWEs understood the recommendations and were incorporating them into the walkdown and area walk-by process. Previously completed checklists were revised to reflect lessons learned from the peer review process.

Based on completion of the walkdown and walk-by peer review activities described, the peer review team concludes that the SWE teams are familiar with and followed the process for conducting seismic walkdowns and area walk-bys in accordance with the Guidance. The SWE teams adequately demonstrated their ability to identify potentially adverse seismic conditions such as adverse anchorage, adverse spatial interaction, and other adverse conditions related to anchorage, and perform anchorage configuration verifications, where applicable. The SWEs also demonstrated the ability to identify seismically-induced flooding interactions and seismically-induced fire interactions such as the examples described in Section 4 of the Guidance. The SWEs demonstrated appropriate use of self-checks and peer checks. They discussed their observations with a questioning attitude, and documented the results of the seismic walkdowns and area walk-bys on appropriate checklists.

One of the Peer Reviewers was present on site for two out of the three weeks of the walkdowns.

SWELs and AWCs documentation was randomly reviewed and discussed with the respective team.

The SWEL items included the following:

1. SWEL-102 CY1-72-lA N2 cylinder

2. SWEL-079 NG-13A CAD SOV

3. SWEL-032, RRV-8

4. SWEL-058 P-10-D RHRPump'

5. SWEL-059 V-10-65B RHR Bypass valve

6. SWEL-005 P-46-1A CS Pump

7. SWEL-061 P-8-1C RHRSW Pump

14. SWEL-003 PCV-3-32B

15. SWEL-020 MCC-9D In addition, as the Peer Reviewer walked to the selected SWEL, a survey of the area to the respective SWEL was also performed.

The AWC items reviewed were in the Reactor Building as follows:

1. AWC-014

2. AWC-027

3. AWC-029

4. AWC-030

5. AWC-034

6. AWC-032

7. AWC-007

8. AWC-009

9. AWC-031

10. AWC-003

11. AWC-013 In all the above SWEL and AWC walkdowns no seismic issues were identified. Housekeeping items identified are captured in CRs listed above.

A second Peer Reviewer checked all SWEL and AWC forms for completeness, checked AWC

-SWEL relationship and selected some SWELs to walkdown.. The SWEL selected were:

1. SWELI -007

2. SWELl-040

3. SWELl-043

Engineering Report No. VY-RPT- 12-00019 Rev. 0 Page 27 of 28 performed as part of the CAP process.

The method used to perform Licensing Bases Evaluations (LBEs) for the Vermont Yankee effort was more conservative than recommended in the Walkdown Guidance document. The Guidance discussed performing an LBE to first determine if a reported condition complies with the plant licensing bases prior to entering the condition in the plant CAP. Then, if the LBE concluded the condition was in compliance with plant licensing bases, it would be so documented and no further effort would be required.

Instead, all potentially adverse seismic conditions identified during the walkdowns and AWBs were immediately entered into the CAP (within several hours of discovery). LBEs performed to establish compliance with the plant licensing bases were included in the dispositions of the CRs.

This approach was preferred by Vermont Yankee since it provided immediate notification to the Main Control Room of all potential adverse impacts. This was reasonable and justifiable since the Vermont Yankee CAP requires immediate assessment of potentially adverse conditions for plant operability, which by definition, required review and understanding of the design and licensing bases of the subject components.

9.2.4 Submittal Report The peer review team was provided with an early draft of this submittal report for peer review.

The peer review team verified that the submittal report met the objectives and requirements of to the 50.54(f) Letter, and documented the NTTF 2.3 Seismic Walkdown program performed in accordance with the Guidance. The peer review team provided the results of review activities to the SWE team for consideration. The SWE team satisfactorily addressed all peer review comments in the final version of the submittal report. The signature of the Peer Review Team Leader provides documentation that all elements of the peer review as described in Section 6 of the Guidance were completed.

• • During implementation of the Seismic Walkdowns SWEL-065 was determined to be inaccessible for inspection. This SWEL number was valve FCV-104-17D, SW/D TRAVELLING SCREEN CONTROL VALVE. It was replaced with Valve LCV-108-3 which is located in the Fuel Oil Pump House. This valve is a similar GIP 07 class valve and is also located in a humid environment as was FCV-104-17D. No other SWELl & SWEL2 items have been changed since the original SWEL approval prior to Seismic Walkdowns.
