SUBJECT:
AUDIT REPORT FOR VOGTLE ELECTRIC GENERATING PLANT UNIT 4, REQUEST FOR LICENSE AMENDMENT:
REINFORCEMENT CHANGES FOR WALL L AND WALL 7.3 (LAR-19-016R1)
By letter dated August 22, 2019 (Agencywide Documents Access and Management System (ADAMS) Accession Number ML19234A327), Southern Nuclear Operating Company (SNC or licensee) requested an amendment to Combined License (COL) Number NPF-92, for Vogtle Electric Generating Plant (VEGP) Unit 4. The amendment proposed to depart from AP1000 Design Control Document (DCD) Tier 2* material that has been incorporated into the Updated Final Safety Analysis Report (UFSAR). The proposed departure consists of changes to Tier 2* information in the UFSAR to change the provided area of horizontal reinforcement for VEGP Unit 4 Wall L and Wall 7.3 from elevation 117'-6" to 135'-3". The NRC issued an audit summary dated October 11, 2019 (ADAMS Accession No. ML19280D872) to document the audit regarding the proposed horizontal reinforcement. Subsequently, by letter dated October 25, 2019, SNC revised its request in LAR-19-016R1 (ADAMS Accession No. ML19298D420), to change the provided area of vertical reinforcement for VEGP Unit 4 Wall L from elevation 117'-6" to 135'-3" in addition to the previously submitted horizontal reinforcement changes.

Report of Regulatory Audit License Amendment Related to Reinforcement Changes for Wall L and Wall 7.3 Vogtle Electric Generating Plant, Unit 4 (LAR 19-016R1)
A. Background By letter dated August 22, 2019 (Agencywide Documents Access and Management System (ADAMS) Accession Number ML19234A327), Southern Nuclear Operating Company (SNC or licensee) requested an amendment to Combined License (COL) Number NPF-92, for Vogtle Electric Generating Plant (VEGP) Unit 4. The amendment proposed to depart from AP1000 Design Control Document (DCD) Tier 2* material that has been incorporated into the Updated Final Safety Analysis Report (UFSAR). The proposed departure consists of changes to Tier 2*
information in the UFSAR to change the provided area of horizontal reinforcement for VEGP Unit 4 Wall L and Wall 7.3 from elevation 117'-6" to 135'-3". The NRC issued an audit summary dated October 11, 2019 (ADAMS Accession No. ML19280D872) to document the audit regarding the proposed horizontal reinforcement. Subsequently, by letter dated October 25, 2019, SNC revised its request in LAR-19-016R1 (ADAMS Accession No. ML19298D420), to change the provided area of vertical reinforcement for VEGP Unit 4 Wall L from elevation 117'-6" to 135'-3" in addition to the previously submitted horizontal reinforcement changes.
The purpose of this audit is to gain a better understanding of the calculations associated with LAR 19-016.
B. Bases This regulatory audit is based on the following:
- VEGP Units 3 and 4 UFSAR Revision 8, Chapter 3, Design of Structures, Components, Equipment and Systems, Appendix 3H, Auxiliary and Shield Building Critical Sections (ADAMS Accession No. ML19171A061).
The audit plan is available in ADAMS under Accession No. ML19248C020.
