SO.OSEWS210.1-36 Revtske 00 PURPOSE:
Document the Screening Evaluation Work Sheets (SEWS) forthe CRAG/CHILLWater Pump ¹12, equipment number 210.1-36.
This SEWS has been prepared as part ofthe commitment to use the SQUG (GIP) methodology to document the seismic adequacy of SSEL components.
CONCLUSION: The four 5/8" diameter cinch anchors are adequate for a 250 pound load based on engineering judgment, the capacities given in Calculation SO.OSQUGANCHOR (Ref. 2) and the anchor bolt tightness check results confirming these anchors are tight.
Therefore, the SQUG outlier for210.1-36 is resolved.
