Seismic Ground Motion at Three Mile Island Unit 2 Independent Spent Fuel StorageInstallation Site in Idaho National Engineering and Environmental Laboratory. Final Report

摘要

The U.S. Department of Energy (DOE) plans to store fuel debris arising fomr the1979 accident at the Three Mile Island Unit 2 (TMI-2) in an independent spent fuel storage installation (ISFSI) at the Idaho National Engineering and Environmental Laboratory (INEEL). Recognizing the significance of seismic design requirements to the proposed TMI-2 ISFSI and complications with regard to the DOE-proposed seismic design approach and the current applicable NRC regulation and standard, the NRC directed the Center for Nuclear Waste Regulatory Analyses techincal bases in commenting on the adequacy and acceptability of the DOE seismic design approach for the TMI-2 ISFSI. The objectives CNWRA seismic investigation are threefold: 10 to conduct an independent review of existing seismic hazard investigations at INEEL, in particular, to identify seismic issues important to siting the proposed TMI-2 storage facility; (2) to evaluate the adequacy the DOE seismic design approach; and (3) to make recommendations regarding the DOE-proposed seismic design approach and design basis earthquake value.
