I -Two 4-drawer filing cabinets located In the southeast comer of the control room are not strapped down and are located roughly 1 inch from a temperature switch control panel. The estimated weight of each cabinet is 500 lbs, and the lateral seismic force on them is estimated to be 70 lbs. Therefore, using engineering judgment, it is unlikely that the filing cabinets can adversely affect the function of the switch control panel during a seismic event.2. -Two metal storage cabinets, approximately 80" tall, are located in the southwest area of the control room. The cabinets are securely anchored with two 114" HIl bolts and using 2" diameter flat washers, approximately 65" from floor level. The anchors for these storage cabinets were secured per Work Order Request #36074.

The space below each question in this checklist should be used to describe any findings identified during the peer review process and how the SWEL may have changed to address those findings.

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

YE] Nr-]The SWELl contains 102 components and addresses all five safety functions from a population of about 750. Many components provide safety functions for multiple systems, and/or are part of frontline support systems. The five safety functions discussed in EPRI Report 1025286 are well represented in the SWEL. Reactivity control, reactor pressure boundary, RC inventory control, DH removal and containment integrity were considered in the selection process.2. Does SWEL 1 include an appropriate representation of items having the following sample selection attributes:

a. Various types of systems?Items included on the SWEL comprise a variety of systems such as Emergency Diesel Generators and Auxiliaries, Service Water System, Component Cooling Water System, Pressure Control, Residual Heat Removal System, Vital A/C and D/C systems.b. Major new and replacement equipment?

Equipment with anchorage modifications as a result of USI A-46/IEEE is included.SWELI-101 and SWELl-102 are replacement and new equipment, respectively.

YO NEI Y0 NO c. Various types of equipment?

YO NEI SWEL I includes at least one example of each of the 21 classes of equipment, except class 11 (chillers).

All classes of equipment except for the one identified class are well represented.

In general, the number of components in each class is proportional to the number of safety-related components of that class in the plant as a whole, except that the number of in-line valves was reduced to allow for the Inclusion of equipment that is anchored because anchored equipment is potentially more vulnerable to seismic loads.EN-DC-1 68 REV 0 Engineering Report No. VTY-RPT-12-00019 Rev. 1 Page 3 of 4 Attachment G ATTACHMENT 9.10 PEER REVIEW CHECKLIST FOR SWEL FORM Sheet 2 of 3 Peer Review Checklist for SWEL d.

YED NM Components are located in different buildings, rooms, and/or on different builidng elevations as well as different enviornments (Inside, outside, temperature, humidity).

The SWEL also includes components located inside primary containment and steam tunnel.e. Equipment enhanced based on the findings of the IPEEE (or equivalent) program? YZ NEI The SWEL includes components that were identified during the IPEEE as being potentially vulnerable to a seismic event.f. Were risk insights considered in the development of SWEL 1? YZ NM Vermont Yankee does not have a seismic PRA. Industry models of PRAs were used to aid in selection.

Additionally, Section 6.2 and Attachment I of the report describe the risk ranking assessment method applied to determine the most risk significant components, 3. For SWEL 2: a. Were spent fuel pool related items considered, and if applicable included in YZ N[" SWEL 2?SWEL 2 includes 11 components for maintaining cooling of the SFP, which are Seismic Category I components.

b. Was an appropriate justification documented for spent fuel pool related items not YZ Nf" included in SWEL 2?Based on reviewer knowledge, it appears that this criterion is met. There were no components that could contribute to rapid SFP draindown that were identified based on review of the information presented in Sections 6.3,1 and 6.3.2 of the report.EN-DC-1 68 REV 0 Engineering Report No. VTY-RPT-12-00019 Rev. 1 Attachment G Page 4 of 4 ATTACHMENT 9.10 PEER REVIEW CHEMCKUST FOR SWEL FORM Shee 3 of 3 Poor Review Checklist for SWEL 4.

Engineering Report No. VTY-RPT-12-00019 Rev. 1 Attachment J Page 1 of 3 Attachment J SWEL 1 Risk Ranking Process Engineering Report No. VTY-RPT-12-00019 Rev. 1 Attachment J Page 2 of 3 ATTACHMENT J SWEL 1 Risk Ranking Process EPRI-TR-1025286 provides guidance for developing the Seismic Walkdown Equipment List (SWEL) and performing the seismic walkdown.

Section 3 of EPRI-TR-1025286 identifies that the SWEL should include consideration of the importance of the contribution to risk for the Structures, Systems, and Components (SSCs).It should be noted that use of risk ranking is only applied in the selection of SSCs included in SWEL-1 group.The SWEL-1 group of SSCs are those associated with maintaining the following five safety functions:

  • Reactor reactivity control" Reactor coolant pressure control" Reactor coolant inventory control* Decay heat removal* Containment function Vermont Yankee does not have a Seismic PRA (SPRA). However, based on insights from previous industry SPRA models, the Level I site LOOP event sequences would identify the equipment that are also generally risk important during seismic events (e.g., EDGs, DC equipment, and other AC-independent equipment such HPCI).Therefore, the risk importance from the VY Level 1 full-power internal events PRA, with a minor modification, was used as input for the SWEL. The minor modification is that only the site LOOP event sequences were used as input for the risk importance measures.

No other PRA model changes were judged required.Super components modeled in the PRA generally include all components modeled on the skid (e.g., EDG, control panel, air start system, etc.). Individual components within the defined PRA component boundary do not need to be identified as separate components for the importance list. However, support system components that are modeled as separate basic events (e.g., EDG Fuel Oil Transfer Pump, ventilation, cooling water, etc.) can be identified as separate components for the importance list.Seismic events may simultaneously damage multiple structures, redundant systems, and components within the plant. Therefore, the risk importance of common cause failure (CCF) events modeled in the PRA were also reviewed and used in the selection process. CCF events represent failure of two or more components (e.g., reactor water level transmitters) during a short period of time as a result of a single shared cause.SSC Importance Measures Determining at-power risk importance required the use of a plant PSA model to calculate SSC relative importance to a pre-defined consequence measure -in this case core damage frequency (CDF). Risk ranking was done using two measures of risk importance:

  • Risk Achievement Worth (RAW)* Fussell-Vesely Importance (F-V)

Engineering Report No. VTY-RPT-12-00019 Rev. 1 Page 3 of 3 Attachment J Calculation of Risk Achievement Worth (RAW)Risk Achievement Worth (RAW) measures the increase in core damage frequency when the component's failure probability is set to 1. That is, a new CDF is calculated with the SSC of interest guaranteed to fail. The equation for RAW is RA W= CDF, CDF>.e where: CDF, = core damage frequency when the component(s) failure probability is set to 1 CDFbase = base core damage frequency Calculation of Fussell-Vesely Importance (F-V)Fussell-Vesely Importance (F-V) measures the decrease in core damage frequency when the component's failure probability is set to 0. That is, a new CDF is calculated with the SSC of interest perfectly reliable or guaranteed to succeed. The equation for F-V is F- V = (CDFbae -CDF°)CDFb.,a where: CDFo = core damage frequency when the component(s) failure probability is set to 0 CDFbse = base core damage frequency SSC Risk Significance After calculation of the importance measures, the risk significance of SSCs were determined using the following criteria: Description Ranking Criteria high risk significance F-V ý! 0.01 -or- RAW ý! 2 high risk significance F-V0.0l -or- RAW>2 Engineering Report No. VTY-RPT-12-00019 Rev. 1 Page 1 of 67 Attachment K Attachment K Deferred Seismic Walkdown Checklists (SWCs)

The space below each of the following questions may be used to record the results of judgments and findings.Additional space is provided at the end of this checklist for documenting other comments.1. Does anchorage of equipment In the area appear to be free of potentially adverse seismic conditions (if visible without necessarily opening cabinets)?

YO NEI UD- N/AD]General inspection was performed at the floor elevation and the elevated platform level for equipment anchorage.

Included was the support systems for the Main Steam Isolation Valves (MSIVs) which were visible through the grating at the platform level. No adverse seismic conditions were noted during this area inspection.

2. Does anchorage of equipment in the area appear to be free of significant degraded conditions?

Equipment anchorage was free of significant degradation.

Some minor surface corrosion was noted where painted surfaces had been breached to bare metal.3. Based on a visual inspection from the floor, do the cable/conduit raceways and HVAC ducting appear to be free of potentially adverse seismic conditions (e.g., condition of supports is adequate and fill conditions of cable trays appear to be inside acceptable limits)?Cable/conduit raceways are adequately supported.

The HVAC Duct above the V23-16 valve is dented. The duct is above a blow out panel that is often removed during Refueling Outages to move MSIV parts in and out of the Steam Tunnel. The dent does not affect the support structure of the duct and there are no adverse seismic interaction concerns.YO NE UD N/AD Y0 ND uD N/AD If the room in which the SWEL item is located is very large (e.g., Turbine Hall), the area selected should be described.

Bldg. Reactor Building Floor El. 252' Room, Area2 Steam Tunnel 4. Does it appear that the area is free of potentially adverse seismic spatial interactions with other equipment In the area (e.g., ceiling tiles and lighting)?

No adverse seismic interaction concerns for area equipment from overhead supported systems. There is a monorail (M-165) that runs above the valve. The trolley on the monorail Is stored approximately 25'North of the valve. There is no credible concern of the trolley or attached chains inadvertently moving and potentially travelling 25'during a seismic event to contact the valve.5. Does it appear that the area is free of potentially adverse seismic interactions that could cause flooding or spray In the area?No potential adverse seismic interactions which could create spray or flooding concerns.6, Does it appear that the area is free of potentially adverse seismic interactions that could cause a fire in the area?No potential adverse seismic interactions which could cause a fire.7. Does it appear that the area is free of potentially adverse seismic interactions associated with housekeeping practices, storage of portable equipment, and temporary installations (e.g., scaffolding, lead shielding)?
