Document the Screening Evaluation Work Sheets (SEWS) forthe AP/125V DC BATTERYBOARD¹11, equipment number BB11.

This SEWS has been prepared as part ofthe commitment to use the SQUG (Glp) methodology to document the seismic adequacy of SSEL components.

CONCLUSION: The BB11 weld and cinch anchor analysis concluded the anchorage is adequate based on the analysis in Attachment A, the cinch anchor capacities given in Calculation SO.OSQUGANCHOR (Ref. 2) and the bolt tightness check results confirming these type of anchors are tight.

Therefore, the SQUG outlier for BB11 is resolved.

DP/BS Caveat 2-Contains only Circuit Breakers and Switches.

DP/BS Caveat 3-Doors Secured.

DP/BS Caveat 4 - Adjacent Cabinets Bolted Together DP/BS Caveat 5-General Configuration Similar to NEMAStandards.

DP/BS Caveat 6 - Adequate Anchorage.

DP/BS Caveat 7-Potential Chatter of Essential Rela s Evaluated.

DP/BS Caveat 8-No Other Concerns.

Yes Yes Yes Yes Yes No Yes*

Yes Is the intent of all the caveats met for Bounding Spectrum?

ANCHORAGE

1. The sizes and locations of anchors have been determined

2. Appropriate equipment characteristics have been determined (mass, CG, natural freq.,

damping, center of rotation).

3. The type of anchorage is covered by the GIP

4. The adequacy ofthe anchorage installation has been evaluated (weld quality and length, nuts and washers, expansion anchor tightness, etc.)

5. Factors affecting anchorage capacity or margin of safety have been considered: embedment length, anchor spacing, free-edge distance, concrete strength/condition, and concrete cracking.

6. For bolted anchorages, an gaps under the base are less than 1/4

7. Factors affecting essential relays have been considered: gaps under the base, capacity reduction for expansion anchors.

8. The base has adequate stiffness and the effect of prying action on anchors has been considered.

9. The strength of the equipment base and the load path to the CG is adequate

10. The adequacy of embedded steel, grout pads or large concrete pads have been evaluated.

11. The anchorage capacity exceeds the demand.

Are anchorage requirements met'?

INTERACTIONEFFECTS Yes Yes Yes Yes Yes Yes Yes Yes Yes Yes

1. Soft targets are free from impact by nearby equipment or structures

2. Ifthe equipment contains sensitive relays, it is free from all impact by nearby equipment or structures.

3. Attached lines have adequate flexibili

4. Overhead equipment or distribution systems are not likely to collapse.

5. No other adverse concerns were found.

Yes Yes Yes Yes Yes Is equipment free of interaction effects'

Floor El: 261.00 Room, Row/Col: A9,10 IMPORTANTNOTE: This SEWS is a composite of the original SQUG pilot plant walkdown conducted in January and February of 1988 by D. Moore, A. Ordonez, W Djordjevic,.RF Oleck, J Valente, D Aelbrecht, J. Reddington, T.

Hester, D. Tahiliani, J. Raby, and F. Feng using the GIP, Revision 1; a supplementary walkdown conducted by RF Starck, F Feng and W Djordjevic in April 1989 still using Revision 1 ofthe GIP, and the final walkdown conducted in April 1993 by W Djordjevic and C Agosta to update the SEWS to Revision 2 GIP requirements as required by USNRC in SSER-2.

+ Contains a GE relay for the emergency seal pump (model 12HFA51A2H); however, NMPC advised that seal pump is not on SSEL, therefore, OK.

One bolt missing in top frame, but of no consequence.

Tray bolted to top of panel.

Adjacent block wall evaluated to IE80-11 program and therefore acceptable for design basis.-

Cabinet is stitch welded to embedded plate that is secured by Cinch anchors (see NMPC drawing C-18801-C, Rev. 3). This makes cabinet an outlier because overturning moment does exceed restoring moment and Cinch anchors willbe subject to tension.

AP/125 V DC BATTERYBOARD ¹11 Building: TB Floor El.: 261.00 Room, Row/Col: A9,10 a.

Identify all the screening guidelines which are not met. (Check more than one ifseveral guidelines could not be satisfied.)

Capacity vs. Demand Caveats Anchorage Seismic Interaction Other b.

Describe all the reasons for the outlier (i.e., ifall the listed outlier issues were resolved, then the signatories would consider this item of equipment to be verified for seismic adequacy).

Embedded channel to which Battery Board is secured is anchored with Cinch (leaded) type anchors; Cinch type anchors are not covered by the GIP.

a.

Defined proposed method(s) for resolving outlier.

Determine actual capacities of Cinch type anchors and compare them to demand loads or retrofit anchorage.

b.

Provide information needed to implement proposed method(s) for resolving outlier (e.g., estimate of fundamental frequency).
