Notice of availability.


The NRC staff is issuing its Final Interim Staff Guidance (ISG) DC/COL-ISG-017 titled “Ensuring Hazard-Consistent Seismic Input for Site Response and Soil Structure Interaction Analyses,” (Agencywide Documents Access and Management System (ADAMS) Accession No. ML100570203). This ISG supplements the guidance provided to the NRC staff in Sections 2.5 and 3.7 of NUREG-0800, “Standard Review Plan (SRP) for the Review of Safety Analysis Reports for Nuclear Power Plants,” March 2007, and DC/COL-ISG-01, “Interim Staff Guidance on Seismic Issues Associated with High Frequency Ground Motion in Design Certification and Combined License Applications,” issued May 19, 2008 (ADAMS Accession No. ML081400293). The NRC staff issues DC/COL-ISGs to facilitate timely implementation of current staff guidance and to facilitate activities associated with review of applications for design certifications and combined licenses by the Office of New Reactors. The NRC staff intends to incorporate the final approved DC/COL-ISG-017 into the next revision of SRP Sections 2.5 and 3.7 and Regulatory Guide 1.206, “Combined License Applications for Nuclear Power Plants (LWR Edition),” June 2007.

Disposition: On August 31, 2009, the NRC staff issued the proposed ISG, DC/COL-ISG-017, “Ensuring Hazard-Consistent Seismic Input for Site Response and Soil Structure Interaction Analyses,” (ADAMS Accession No. ML092230455) to solicit public and industry comment. The NRC staff received comments on the proposed guidance. This final issuance incorporates changes from the comments. The NRC staff responses to these comments can be found in ADAMS Accession No. ML100570289.
