Guidelines have been developed to evaluate the seismic adequacy of the anchorage of various classes of electrical and mechanical equipment in nuclear power plants covered by NRC Unresolved Safety Issue A-46. The guidelines consist of screening tables that give the seismic anchorage capacity as a function of key equipment and anchorage fasteners, inspection checklists for field verification of anchorage adequacy, and provisions for outliers that can be used to further investigate anchorages that cannot be verified in the field. The screening tables are based on an analysis of the anchorage forces developed by common equipment types and on strength criteria to quantify the holding power of anchor bolts and welds. The strength criteria for expansion anchor bolts were developed by collecting and analyzing a large quantity of test data.
