The cabinetinternals were inspected and no missing hardware or fasteners were observed. The cables inside the cabinet had adequate flex and no other adverse seismic conditions were noted.

The cabinet was identified to contain misc. trash at the bottom of the cabinet. SWEs determined that this trash would have no impact to the equipment during a seismic event and only representeda housekeeping concern. OPS was notified and the miscellaneous trash was removed while the cabinet panel was open.

Comments (Additional pages may be added as necessary)

SWC completed originally on 8/28/12. A WB located with package F2-51.

Second walkdown was performed to inspect cabinet internals. No adverse seismic conditions were noted.

During the IPEEE walkdowns, Q2R21L LOOID was identified as an IPEEE Outlier due to the intemal circuitbreaker supportsystem being anchored to the cabinet with only 2 of 4 fasteners. During walkdown performed on 3/25/13, the circuit breakersupport system was properlyanchored using 4 of 4 fasteners. As a result, it is concluded that the IPEEE Outlier has been resolved.

Two Agastat relays in upper east panel are mounted with two bolts.

The relays were seismically qualified with four bolts and therefore are missing two bolts. It is evident that four bolt holes were drilled into the panel door, however the relays were mounted too high and only two bolts could be provided. CR 589508 was written to document this condition.

The tall cabinet on the west side of the front of the load center contains a plastic wire chase for the routing of cable. The cover of the wire chase had previously slid down onto a heating element at the base of the panel and had melted. The cover was restored to its original position, but no action was taken to restrainit from future sliding and therefore a potential fire hazard exists during or after a seismic event.

CR589480 was written to document this potentially adverse seismic condition.

The cabinet internalswere inspected and all routed cables have been determined to have adequate flex, routed in an acceptable fashion, and pose no adverse seismic condition.

CR 640948 has been written to document the following condition identified: There were eleven instances identified where seismically qualifiedAgastat Relays were installed with less than the standard four requiredmounting screws. This condition has been evaluated for the 2A MCC, which is attachedto TE 640206, and it has been determined that the currentmounting configurationdoes not adversely impact the functionality of the relay in any of its operatingmodes (before, during, or after a DBE). As a result, the condition does not bring into question the operabilityof the relays. A copy of the evaluation has been attached to the SWC.

Although the relays remain functional and operable, the relays should be installed with the intended mounted configuration of four screws at the earliestopportunity.

Second walkdown was performed on 5/15/13 to inspect the MCC 2A cabinet internals. No adverse seismic conditions were noted during performance of the final walkdown.

02R I 7BOO 1-A was identified as a Seismic Outlierduring the IPEEE walkdowns. There was a potential interactionfrom an unrestrainedcart and inadequateanchorage.The IPEEE Outlier has been determined to be resolved. There was not an unrestrainedcart in the area and the MCC has been anchored to the rearwall at the top of the cabinetin multiple locations.

SNCF164-RPT-02, VERSION 2.0 SENERCON 05-16-13 TECHNICAL EVALUATION FOR AGASTAT RELAY MODEL #WS E7012AC004 AND E7012AF004 IN MCC 2A (Q2RZ.7Beeel-A) AB EL. 139' ROOM NO. 2332, FNP UNIT 2 IN RESPONSE TO CR# , REF. TE-640206 PROBLEM: Eleven (11) relays requiring four screw mounting configurations were found in the field with either only two or three mounting screws.

Demonstrate the technical adequacy of the anchorage and the seismic adequacy of the relays to perform their functions before, during, and after a DBE.

DETAILS: The as-found configurations of the relays are as follows:

four (4) relays were found with three screws, three (3) relays were found with two screws in diagonal corners; three (3) relays were found with two screws in a horizontal line and; one (1) relay was found with two screws in a vertical line.

The relays' associated breaker cubicle locations and affected loads are as documented below (taken from the FNP U2 Load List A351199):

Q2R17BKRFAA4 - 2A RHR/LHSI PUMP ROOM COOLER FAN Q2R17BKRFAA7 - 2A CTMT SPRAY PUMP ROOM COOLER FAN Q2R17BKRFAB3 - 2A PENETRATION ROOM RECIRC FAN Q2RI7BKRFAF7 - 2A REACTOR CAVITY COOLING FAN Q2R17BKRFAH5 - CHARGING/HHSI PUMP ROOM COOLER 2A FAN Q2R17BKRFAI4 - CCW PUMP ROOM COOLER 2A FAN Q2R17BKRFA34L (2 Relays) - 2D CTMT POST LOCA AIR MIXING FAN Q2R17BKRFA34R (2 Relays) - 2C CTMT POST LOCA AIR MIXING FAN Q2R17BKRHA02 - 2A PENETRATION ROOM EXHAUST FAN RESPONSE: Seismic test report U-419260 Version 3.0 demonstrates that the subject relays were tested and found adequate for their non-operating mode (relay coil de-energized off-delay relays timed out), operating mode (relay coil energized on-delay relays timed out), and transitional mode (time relay delay) with nominal rated voltage less 10% applied to coils.

APPROACH: This evaluation consists of two elements to be verified; (a) structural adequacy of the anchorages, and (b) seismic adequacy of the relays in their as-found conditions.

The evaluation focusses on the assessment of the as-found configurations of 2 screws on a horizontal line and two screws on a vertical line. These assessments envelope all of the subject relay configurations.

ýj ENERCON 05-16-13 TECHNICAL EVALUATION FOR AGASTAT RELAY MODEL #'S E7012AC004 AND E7012AF004 IN MCC 2A (Q2R17B0e01-A) AB EL. 139' ROOM NO. 2332, FNP UNIT 2 IN RESPONSE TO CR# , REF. TE-64e2e6 A. Anchorages were demonstrated to have an interaction ratio of 0.28.

This was based on the accelerations from the horizontal DBE with 5%

damping and vertical DBE with 5% damping amplified with an in-panel amplification factor and a multi-mode factor. The capacity of the screw was compared to the demand on the screws. The multi-mode factor used in the computation was taken from IEEE 344-1975 and the in-panel amplification factor was taken from EPRI NP-7148 and Calculation No.

C891579.

Note: Assessment of the interaction ratio for loads on the screws should normally include the effect of shear in combination with the tensile loads. In this case, since the assessment is very conservative, as in the case of using an amplification factor of 7 for the MCCs (in lieu of an amplification factor of 3), this was neglected. This is reasonable.

8. The relays were demonstrated to operate without chatter based on the computation of the stiffness of the mounting plate with the two most conservative configurations of as-found, existing anchorage. For these cases it is shown that the stiffness of the as-found condition does not contribute to the amplification of the accelerations acting on the relays.

Therefore, the testing conducted in accordance with the referenced seismic report remains valid and applicable to the as-found configurations.

CONCLUSION: The as-found configurations of the eleven subject relays do not adversely impact the seismic qualification of the relays, nor their functionality in any of their operating modes (during, before, and after a DBE).

However, the missing screws need to be re-installed to be consistent with the seismic test configuration and to maintain all design margins.

pac.;t* FZ - I'. . C'Lol, Final walkdown performed on 3/19/13 to inspect cabinet internals.No adverse seismic conditions were noted during performance of the final walkdown.

02R1 7BO98-A was identified as a Seismic Outlierduring the IPEEE walkdowns. The outliers, as documented in the SEWS package for Q2RI 7BO98-A dated 7/5/93 were the following:

1.)MCC has a weld in the rear comers and no otherlocations in the rear.This weld configuration results in an unsupportedspan of 8'4" between welds to resistuplift.

2.) The unsupportedspan in #1 could also be an impact source which could potentiallyresult in relay chatter 3.) 0" gap between back top of MCC and concrete mass on the adjacent wall. This is also a potentialimpact source.

The proposed methods for resolving the outlier was either to attach the MCC top to the adjacent wall (would resolve all 3 concerns listed above) or if modal testing could demonstrate that fn > 8 Hz, then the concrete mass could be removed, which would remove the interactionbetween the wall and the rear of the MCC.

As stated in Attachment E of the SEWS Package,adding anchorageto the rear top of the MCC at the left, center, and right sides of the cabinet would resolve the potential impactsources between the concrete patch and the MCC and the potential impact source as a result of the large unsupported span. The walkdown confirmed that the MCC has been anchored to the wall in the three recommended locations.(Reference Sheets 9, 10, and 11 of 12) Additionally,the concrete mass identified during the IPEEE walkdowns has also been verified to be removed (Reference Sheet 12 of 12). As a result, all IPEEE outliers have been resolved.

The cabinet internalswere inspected and no missing fasteners were observed. All internal connections and routed cables have been determined to be adequate and pose no adverseseismic condition.Minor housekeeping was identified under the MCC but this does not affect the seismic functions of the MCC. Additionally, two cabinets containedfailed reset switches which were hanging inside the cabinet panels door. It has been determined that these are soft targets and would not affect or strike components during a seismic event. The switches are marked with deficiency tags and have existing WOs to repairthem, therefore no additionalCRs are warranted.

An external inspection of the cabinetconfirms that the IPEEE vulnerabilityhas been resolved. SEWS package dated 7/3/93 identified inadequateanchorageas a vulnerability.This has been resolved by attaching the two cabinets together, This configurationis judged to be an adequateresolution by the SWEs. A piece of angle has also been used to prevent the top portion of the cabinetfrom overtuming. The angles are sufficient to resist the horizontal loading and prevent loading the rigid conduitin the overhead.

Comments (Additional pages may be added as necessary)

SWC completed originally on 8/24/12.

Secondary Walkdown performed on 2/7/13 to inspect cabinetinternals.

Follow-up walkdown performed on 8/13/13 to confirm IPEEE vulnerability has been resolved.

Location: Bldg. CTMT Floor El. 175 Room, Area' PZR Cubicle Instructions for Completing Checklist This checklist may be used to document the results of the Area Walk-By near one or more SWEL items. 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.

I. Does anchorage of equipment in the area appear to be free of YM NrO UCI N/AC potentially adverse seismic conditions (if visible without necessarily opening cabinets)?

All anchoredequipment has been determined to be sufficiently supported and anchoredsuch that no damage would occur during a seismic event.

2. Does anchorage of equipment in the area appear to be free of significant YN NO UC N/A0 degraded conditions?

Minor surface oxidation was noted on some of the supports located within the PressurizerCubicle. Determined to be only surface oxidation with no visible wastage and to have no impact on the associated equipment. This issue has been previously identified by the coating's program. (Ref. CR 623586)

3. Based on a visual inspection from the floor, do the cabletconduit YU NCi UCi N/A[-

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)?

A unistrut was found mounted to the interiorof the PressurizerCubicle wall with the lower of two supporting anchors (hilti bolts) relaxed. The unistrut was inspectedand was found to not be supporting any equipment and was not in contact with associatedequipment, cables, or conduits. A pull test was performed on the unistrut and it was determinedto be adequatelyanchored to prevent any potentially adverse seismic interactions with nearby equipment.

4. Does it appear that the area is free of potentially adverse seismic spatial Y9 N['I UC N/AC interactions with other equipment in the area (e.g., ceiling tiles and lighting)?

The spatialinteraction is SAT.

' If the room in which the SWEL item is located is very large (e.g., Turbine Hall), the area selected should be described.

This selected area should be based on judgment, e.g., on the order of about 35 feet from the SWEL item.

5. Does it appear that the area is free of potentially adverse seismic Y[D NEI U0 N/AD interactions that could cause flooding or spray in the area?

No seismic interactions were identified which would result in flooding or spraying of the area during a seismic event.

6. Does it appear that the area is free of potentially adverse seismic YID NEI UD N/AU interactions that could cause a fire in the area?

No fire hazards were identified in the area.

7. Does it appear that the area is free of potentially adverse seismic Y[@ NO UE N/AC interactions associated with housekeeping practices, storage of portable equipment, and temporary installations (e.g., scaffolding, lead shielding)?

There is currently temporary Installationsand equipment in the area.

This equipment is associated with the current 2R22 Refueling Outage and will be removed priorto returning the Unit online. As such, no adverse affect to equipment is anticipated.

8. Have you looked for and found no other seismic conditions that could YZ NE UC adversely affect the safety functions of the equipment in the area?

No otherconditions were found which could affect the equipment located in the PressurizerCubicle.

Comments (Additional pages may be added as necessary)

Duringnormal operations,a missile shield (grating)is installed over the Pressurizercubicle which would prevent any overhead equipment external to the Pressurizerfrom coming in contact with the Structures, Systems, or Equipment.
