Revision 7 I7 SO.OSEWS7&69 g /rg 00 PURPOSE'ocument the Screening Evaluation Work Sheets (SEWS) for the AP/600 TO 120/208 VTRANSFORMER, equipment number 167A.

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

CONCLUSION: The four welds and the four 5/8" diameter cinch anchors are adequate based on the anchor analysis in Attachment A, the cinch anchor capacities given in Calculation SO.OSQUGANCHOR (Ref. 2) and the anchor bolt tightness check results confirming these anchors are tight.

Therefore, the SQUG outlier for 167A is resolved.

1. The sizes and locations of anchors have been determined
2. Appropnate 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 of the 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, any 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.

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 of the 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.
