U.S. Nuclear Regulatory Commission Audit Summary for Vogtle Electric Generating Plant Units 3 and 4 Request for License Amendment and Exemption Regarding Changes to the Building Gap between the Nuclear Island and Adjacent Buildings (LAR-18-002)
April 2018 Purpose The Regulatory Audit was conducted to examine and evaluate technical information in order to confirm that the differential settlement at the Vogtle Electric Generating Plant (VEGP) Units 3 and 4 does not have adverse impact on the gaps between the nuclear island and adjacent buildings, as concluded in License Amendment Request (LAR)18-002, Changes to the Building Gap between the Nuclear Island and Adjacent Buildings, VEGP Units 3 and 4 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML18032A359). The staffs review of the VEGP Units 3 and 4 documentation during this audit supports the staffs review of LAR 18-002. The purpose for the audit is documented in the audit plan (ADAMS Accession No. ML18089A282).
Background
On February 1, 2018, Southern Nuclear Operating Company (SNC) submitted VEGP Units 3 and 4 LAR-18-002 to the U.S. Nuclear Regulatory Commission (NRC). The requested amendment includes changes to revise the Updated Final Safety Analysis Report in the form of departures from the incorporated plant-specific Design Control Document (DCD) Tier 2* and Tier 2 information and involves related changes to plant-specific Tier 1 information, with corresponding changes to the associated combined license Appendix C information.
Specifically, the requested amendment proposes changes to relax the minimum gap requirement above grade between the nuclear island and the annex building/turbine building and to remove the minimum gap requirement for the radwaste building from the Inspections, Tests, Analyses and Acceptance Criteria.
VEGP Units 3 and 4 LAR-18-002 on pages 9 and 10 of Enclosure 1 states that differential settlement of foundations may impact the gaps between the nuclear island and adjacent buildings and that differential settlement of foundations is evaluated based on the VEGP Units 3 and 4 settlement survey data collected from the site specific settlement monitoring program for potential impact on the gap between the nuclear island and adjacent buildings. SNCs conclusion that the differential settlement does not have adverse impact on the gaps between the nuclear island and adjacent buildings is based on the settlement survey data.
The staff performed an audit to confirm that the differential settlement does not have adverse impact on the gaps between the nuclear island and adjacent buildings by reviewing settlement survey data demonstrating that the nuclear island and the turbine building foundations have deflected more in the center, and the annex building foundation has deflected uniformly after all construction stages.
Enclosure
Regulatory Bases This regulatory audit is based on the following:
Title 10 of the Code of Federal Regulations (10 CFR) Part 50, Appendix A, General Design Criterion 1, Quality standards and records, as it relates to the requirement that structures, systems, and components (SSCs) important to safety be designed, fabricated, erected, and tested to quality standards commensurate with the importance of the safety functions to be performed. It also requires that appropriate records of the design, fabrication, erection, and testing of SSCs important to safety be maintained by or under the control of the nuclear power unit licensee throughout the life of the unit.
10 CFR Part 50, Appendix B, Quality Assurance Criteria for Nuclear Power Plants and Fuel Processing Plants, as it relates to quality assurance requirements for the design, fabrication, construction, and testing of those SSCs of nuclear power plants that prevent or mitigate the consequences of postulated accidents that could cause undue risk to the health and safety of the public.
Audit Location and Date This audit took place on April 5, 2018. The audit was conducted at the Westinghouse Electric Company offices located in Rockville, Maryland.
Audit Team Assignments
- Zuhan Xi, Audit Lead, Geotechnical Engineer, Geoscience and Geotechnical Engineering Branch, Office of New Reactors (NRO)
- SV0-0500-XCR-800030 R0, VEGP Units 3 and 4 Settlement Survey Data
- APP-1000-GEF-231 R0, Adjacent Buildings Displacements Audit Activities/Summary During the audit, the NRC staff reviewed the above documents.
The staff examined the survey data and associated plots for past few years from beginning of construction stage to current stage. The staff discussed with SNCs engineer about the survey data and associated plots, as well as the comparison between measured actual settlements and calculated settlements by analytical mode. The staff verified that the patterns of differential settlements for the foundations of the nuclear island, turbine building, and annex building, are in agreement with the description in Enclosure 1 of VEGP Units 3 and 4 LAR-18-002. The staff noted the surveyed foundations settlement are much less than calculated settlements by analytical model. The staff also noted that all settlements and differential settlements are well under the limits of AP1000 DCD.
The NRC staff reviewed the documents listed in this audit report and confirmed that the differential settlement does not have adverse impact on the gaps between the nuclear island and adjacent buildings and that the settlement survey data supports LAR 18-002. The staff finds the licensees differential settlement conclusions to be reasonable to support LAR 18-002 for VEGP Units 3 and 4.
Exit Briefing The staff informed SNC that the audit confirmed the differential settlement conclusions to be reasonable to support LAR 18-002 for VEGP Units 3 and 4.
