Virgil C. Summer Nuclear Station, Units 2 and 3

The U.S. Nuclear Regulatory Commission (NRC) is considering issuance of an amendment to Combined Licenses (NPF-93 and NPF-94), issued to South Carolina Electric and Gas (SCE&G) and South Carolina Public Service Authority (Santee Cooper) (the licensee), for construction and operation of the Virgil C. Summer Nuclear Station (VCSNS), Units 2 and 3 located in Fairfield County, South Carolina. The proposed amendment departs from Tier 2* and associated Tier 2 information in the VCSNS Units 2 and 3 Updated Final Safety Analysis Report (UFSAR) (which includes the plant specific Design Control Document Tier 2 information) to demonstrate that the mechanical weldable couplers to structural steel weld capacity required by the American Concrete Institute (ACI) 349-01 is satisfied using the American Institute of Steel Construction (AISC) N690-1994 analysis and testing provisions.
