Virgil C. Summer Nuclear Station, Units 2 and 3; South Carolina Electric and Gas; Liquid Radwaste System Consistency Changes

摘要

The U.S. Nuclear Regulatory Commission (NRC) is granting an exemption to allow a departure from the certification information of Tier 1 of the generic design control document (DCD) and issuing License Amendment No. 10 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 the VCSNS Tier 1 (COL Appendix C) Figure 2.3.10-1, Liquid Radwaste System (WLS), and Updated Final Safety Analysis Report (UFSAR) Tier 2 tables, text and figures to align VCSNS Tier 1 with Tier 2 information provided in the UFSAR and to achieve consistency within VCSNS Tier 1 material by (1) changing the safety classification of the Passive Core Cooling System (PXS) and Chemical and Volume Control System (CVS) compartment drain hubs, (2) changing the connection type from the PXS Compartments drains A and B to a header to match the design description, (3) changing the valve types for three valves in the Tier 1 figure to conform
