SUBJECT:
AUDIT PLAN FOR VOGTLE ELECTRIC GENERATING PLANT UNITS 3 AND 4, REQUEST FOR LICENSE AMENDMENT:
ENGINEERED SAFETY FEATURE SAFEGUARDS ACTUATION TECHNICAL SPECIFICATIONS APPLICABILITY CHANGES (LAR 18-011)
By letter dated May 18, 2017 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML18138A396), Southern Nuclear Operating Company (the licensee) requested an amendment to Combined License Numbers NPF-91 and NPF-92, for Vogtle Electric Generating Plant (VEGP) Units 3 and 4.
The requested amendment requested changes to the Technical Specification (TS) Limiting Condition for Operation (LCO) 3.3.8, Engineered Safety Feature Actuation System (ESFAS)
Instrumentation, related to Safeguard Actuation Functions. Various ESFAS Functions require Applicability and corresponding Actions changes to more accurately reflect their operation and related safety analysis assumptions.
The requested amendment revises the licensing basis information regarding the following:
TS 3.3.8 Required Action E.2 is revised to state: Reduce Reactor Coolant System (RCS) pressure below P-11 (Pressurizer Pressure) interlock.
New TS 3.3.8 Required Action E.3 is added stating: Establish RCS boron concentration greater than or equal to that necessary to meet the SDM requirements at an RCS temperature of 200°F, with a Completion Time of 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

New Table 3.3.8-1 Footnote (l) is added, stating: Below the P-11 (Pressurizer Pressure) interlock and RCS boron concentration is less than that necessary to meet the SDM requirements at an RCS temperature of 200°F.
TS Table 3.3.8-1 Function 24 Applicability is revised to remove MODE 4.
TS Table 3.3.8-1 updated Footnotes (c) and new Footnote (l) are applied to Table 3.3.8-1 Functions 5, 11, and 24, MODE 3 Applicability.
TS Table 3.3.8-1 new Footnote (m) is added, stating: Below the P-11 (Pressurizer Pressure) interlock when Steam Line Pressure - Low 2 is not blocked and applied to Table 3.3.8-1 Function 24, Applicability MODE 3.

Enclosure UNITED STATES NUCLEAR REGULATORY COMMISSION AUDIT
SUMMARY
FOR THE REGULATORY AUDIT OF SOUTHERN NUCLEAR OPERATING COMPANY VOGTLE ELECTRIC GENERATING PLANT UNITS 3 AND 4 REQUEST FOR LICENSE AMENDMENT: ENGINEERED SAFETY FEATURE SAFEGUARDS ACTUATION TECHNICAL SPECIFICATIONS APPLICABILITY CHANGES (LAR-18-011)
DOCKET NO.52-025 52-026 LICENSEE:
SOUTHERN NUCLEAR OPERATING COMPANY LICENSEE CONTACT:
Wes Sparkman DURATION:
August 27, 2018 to August 31, 2018 LOCATIONS:
VEGP-Designated Electronic Reading Room A.
BACKGROUND Southern Nuclear Operating Company (SNC) submitted by a letter dated May 18, 2018, to the U.S.
Nuclear Regulatory Commission (NRC) a request for license amendment Engineered Safety Feature Safeguards Actuation Technical Specifications Applicability Changes (LAR 18-011).
The purpose of the audit is to review the reports and calculation methodology needed by staff to verify the information and conclusions in the Request for License Amendment and Exemption:
Engineered Safety Feature Safeguards Actuation Technical Specifications Applicability Changes (LAR 18-011) submitted by SNC for the Vogtle Electric Generating Plant Units 3 and 4, in License Amendment Request (LAR)18-011 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML18138A396).
B.
REGULATORY AUDIT BASIS This regulatory audit is based on the following regulations:
Title 10 to the Code of Federal Regulations Part 50, Appendix A, GDC 20, Protection System Functions, requires that the protection system shall be designed (1) to initiate automatically the operation of appropriate systems including the reactivity control systems, to assure that specified acceptable fuel design limits are not exceeded as a result of anticipated operational occurrences, and (2) to sense accident conditions and to initiate the operation of systems and components important to safety.
The NRC staff will follow NRO Office Instruction NRO-REG-108 (Revision 0), Regulatory Audits, (ADAMS Accession No. ML081910260) in performing the audit of the reports and calculations cited below.
2 C.
Regulatory Audit Scope The primary scope of this audit is the review of analyses referenced in LAR 18-011 to support the proposed changes to TS LCO 3.3.8, Table 3.3.8-1, Function 24 in regards to the following text in of LAR 18-011 on page 10 of 15:
"The analysis evaluated three cases, with variations in PORV position and operator action times (i.e., in cooldown mid-position with operator response at 30 minutes and 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />, and failed wide open with operator response at 30 minutes). The results of these cases were compared against the full power Steam Generator Tube Rupture (SGTR) evaluation from UFSAR Chapter 15, and the full power SGTR evaluation bounded all three cases with respect to Total Flashed Break Flow, Total Break Flow, and Total Ruptured Steam Generator Steam Releases. The analysis concludes that the times selected for the operator response to isolate the PORV flow path are not critical to the conclusion that the full power analysis is limiting."
However, reference to the discussed analysis is not provided in the LAR. Therefore, the staff will review licensee-provided evaluation for SGTRs to verify the licensee statement that the analysis supports the conclusion that automatic PORV and Block Valve isolation is not required in MODE 3 (below P-11) and MODE 4 (with RCS temperature greater than or equal to 350°F)." as stated in LAR 18-011.
D.
Information and Other Material Necessary for the Regulatory Audit The following documents are to be made available to the NRC staff either at a local office or in the Electronic Reading Room (eRR):
- 1. The Westinghouse Nuclear Safety Advisory Letter 02-14, Steam Line Break During Mode 3 for Westinghouse NSSS Plants, discussed in Enclosure 1, Section 2.A., Safeguards Actuation.
- 2. The evaluation discussed in Enclosure 1, Section 2.C., Power Operated Relief Valve and Block Valve Isolation, performed to demonstrate that the full power SGTR is limiting.
Other documents may be requested based on the staffs review of the above documents.
Appropriate handling and protection of proprietary information shall be acknowledged and observed throughout the audit.
E.
Audit Team The following are the NRC audit team members:
Peter Hearn, Senior Project Manager, Lead Donald E. Palmrose, Senior Reactor Engineer, Technical Reviewer Marie Pohida, Senior Reliability and Risk Analyst, Technical Reviewer The following are the licensee contacts:
Wes Sparkman (SNC)
3 F.
Logistics The NRC staff will address in the audit report the technical areas identified in the Regulatory Audit Scope of this audit plan along with presenting the audit outcomes.
The audit will be conducted in support of the schedule for completion of the LAR 18-011 review with entrance and exit dates to be determined. The level of effort is estimated to be a total of 40 hours4.62963e-4 days <br />0.0111 hours <br />6.613757e-5 weeks <br />1.522e-5 months <br /> to perform the audit and issue the audit report.
Depending on the availability of the licensees documentation, the audit is planned to be conducted between August 27, 2018 and August 31, 2018. The audit is intended to be conducted from the NRC Headquarters via the licensees eRR; however, the audit may be performed at a local office of the licensee, if the technical information is only retained in hard copy.
The NRC staff acknowledges the proprietary nature of the information requested. It will be handled appropriately throughout the audit. While the NRC staff will take notes that will be marked as proprietary and will not remove hard copies or copy electronic files.
G.
Requests Special If necessary, any circumstances related to the performance of the audit will be communicated to Peter Hearn at 301-415-1189 or via e-mail address at Peter.Hearn@nrc.gov.
H.
Deliverables At the completion of the audit, the NRC staff will prepare an audit report within 45 days that will be declared and entered as an official agency record in ADAMS. The audit outcome may be used to identify any additional information to be submitted for making regulatory decisions, and will assist the NRC staff in the issuance of requests for additional information (if necessary) in completing its review of LAR 18-011. With the anticipated exit telecom on September 5, 2018, the audit report will be completed by September 24, 2018.
