PURPOSE'ocument the Screening Evaluation Work Sheets (SEWS) for the AP/600 TO 120/208 V TRANSFORMER, 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.

CQ55JYLEHIR OUTLIER I MPORTANT NOTE: 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 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.

Anchorage: Transformer is anchored by four 1" welds 1/8" thick.
