This NUREG contains the Standard Technical Specifications (STS) for Westinghouse Advanced Passive 1000 (AP1000) plants. This NUREG is based on the generic technical specifications (TS) of the AP1000 design certification rule, Appendix D, "Design Certification Rule for the AP1000 Design," to Title 10 of the Code of Federal Regulations (10 CFR) Part 52, "Licenses, Certifications, and Approvals for Nuclear Power Plants." This NUREG is also based on the plant-specific TS for Vogtle Electric Generating Plant (VEGP) Unit 3, for which the first Combined License (COL) under 10 CFR Section 52.97, "Issuance of Combined Licenses," was granted by the Nuclear Regulatory Commission (NRC) (COL No. NFP-91), as revised on September 9, 2013, by Amendment 13 to the VEGP Unit 3 COL (78 FR 64541) (Agencywide Documents Access and Management System Accession No. ML13238A337).
The AP1000 generic TS were modeled on the format and applicable content of improved STS for pre-AP1000 Westinghouse plants, NUREG-1431, "STS Westinghouse Plants," Revision 2, issued in 2001. Accordingly, the AP1000 STS are also based on applicable NRC-approved generic changes to NUREG-1431 since Revision 2 (with a few exceptions), which have been incorporated in improved STS Revision 4, issued in 2012. In addition, the AP1000 utilities and NRC staff made editorial changes that improve the AP1000 STS NUREG's clarity and useability. Many of the changes to the AP1000 generic TS, which are reflected in this initial version of the AP1000 STS NUREG, result from the experience gained from plant operation using improved plant-specific TS modeled on NUREG-1431 and extensive public technical meetings and discussions among the NRC staff and various nuclear power plant licensees and the Nuclear Steam Supply System (NSSS) Owners Groups.
The improved STS were developed based on the limiting conditions for operation selection criteria in the Final Commission Policy Statement on Technical Specifications Improvements for Nuclear Power Reactors, dated July 22, 1993 (58 FR 39132), which were subsequently codified by changes to 10 CFR 50.36, "Technical Specifications," (60 FR 36953). Licensees of pre-AP1000 Westinghouse plants are encouraged to upgrade their technical specifications consistent with those criteria and conforming, to the practical extent, to Revision 4 of the improved STS. Likewise, licensees of AP1000 plants are encouraged to update their technical specifications to conform, to the practical extent, to Revision 0 of the AP1000 STS. Licensees adopting portions of the STS to existing technical specifications should adopt all related requirements, as applicable, to achieve a high degree of standardization and consistency.
