Virgil C. Summer Nuclear Station, Units 2 and 3; South Carolina Electric and Gas; Change to Information in Tier 1 Table 3.3-1

Краткое содержание

The U.S. Nuclear Regulatory Commission (NRC) is issuing an exemption to allow a departure from the certification information of Tier 1 of the generic design control document (DCD) and License Amendment No. 4 to Combined Licenses (COL), NPF-93 and NPF-94. The COLs were 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 amendment changes requested improve the clarity and accuracy of the Tier 1 information located in Table 3.3-1, "Definition of Wall Thicknesses for Nuclear Island Buildings, Turbine Buildings, and Annex Building," which describes wall and floor thicknesses in the plant. The granting of the exemption allows the changes asked for in the amendment. Because the acceptability of the exemption was determined in part by the acceptability of the amendment, the exemption and amendment are being issued concurrently.
