U.S. Nuclear Regulatory Commission Document Control Desk Washington, DC 20555-0001 Southern Nuclear Operating Company Vogtle Electric Generating Plant Unit 4 ITAAC Closure Notification on Completion of ITAAC 2.5.02.08a.ii [Index Number 540]
Ladies and Gentlemen:
In accordance with 10 CFR 52.99(c)(1), the purpose of this letter is to notify the Nuclear Regulatory Commission (NRC) of the completion of Vogtle Electric Generating Plant (VEGP)
Unit 4 Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC) Item 2.5.02.08a.ii [Index Number 540], for verifying the Protection and Safety Monitoring System (PMS) provides visual alerts as specified. The closure process for this ITAAC is based on the guidance described in NEI-08-01, Industry Guideline for the ITAAC Closure Process under 10 CFR Part 52, which is endorsed by the NRC in Regulatory Guide 1.215.
This letter contains no new NRC regulatory commitments. Southern Nuclear Operating Company (SNC) requests NRC staff confirmation of this determination and publication of the required notice in the Federal Register per 10 CFR 52.99.
If there are any questions, please contact Kelli Roberts at 706-848-6991.
Respectfully submitted, Jamie M. Coleman Regulatory Affairs Director Vogtle 3 & 4

U.S. Nuclear Regulatory Commission ND-23-0301 Enclosure Page 2 of 6 ITAAC Statement Design Commitment 8.a) The PMS provides for the minimum inventory of displays, visual alerts, and fixed position controls, as identified in Table 2.5.2-5. The plant parameters listed with a "Yes" in the "Display" column and visual alerts listed with a "Yes" in the "Alert" column can be retrieved in the MCR.
The fixed position controls listed with a "Yes" in the "Control" column are provided in the MCR.
Inspections/Tests/Analyses ii) An inspection and test will be performed to verify that the plant parameters are used to generate visual alerts that identify challenges to critical safety functions.
Acceptance Criteria ii) The plant parameters listed in Table 2.5.2-5 with a "Yes" in the "Alert" column are used to generate visual alerts that identify challenges to critical safety functions. The visual alerts actuate in accordance with their correct logic and values.
ITAAC Determination Basis Inspection and testing were performed to verify that the Protection and Safety Monitoring System (PMS) provides visual alerts as identified in Table 2.5.2-5 (Attachment A). The inspection and testing confirmed that the plant parameters listed with a "Yes" in the "Alert" column are used to generate visual alerts that identify challenges to critical safety functions and that these visual alerts actuate in accordance with their correct logic and values.
ITAAC 2.5.02.08a.ii was completed by:
Factory Acceptance Testing - Channel Integration Test and System Integration Test for visual alerts that identify challenges to critical safety functions.
Site software installation and regression test - Hardware and software integration verification and testing of post system delivery changes.
The Factory Acceptance Testing (FAT) followed the guidance of NEI 08-01 (Reference 1)
Section 9.4 for the as-built tests to be performed at other than the final installed location. The FAT was performed in accordance with the Software Program Manual for Common Q Systems WCAP-16096 (Reference 2), AP1000 Protection and Safety Monitoring System Test Plan (Reference 3), AP1000 Protection and Safety Monitoring System Qualified Data Processing System Channel Integration Test Procedure (Reference 4), and applicable Codes and Standards described in Vogtle 3 and 4 UFSAR Chapter 7 (Reference 11).
During the FAT, the plant parameters were simulated and adjusted to create applicable alert conditions, PMS outputs were monitored, and it was confirmed that the visual alerts actuated in accordance with their correct logic and values. This testing was performed in accordance with FAT Test Procedure APP-PMS-T1P-010 (Reference 4). The results of the PMS testing are documented in the FAT test reports APP-PMS-T2R-010 (Reference 5) and SV4-PMS-T2R-150 (Reference 6). The FAT results confirm that the PMS inputs and outputs, logic and installed software functioned correctly to provide for the visual alerts, as identified in Attachment A.
U.S. Nuclear Regulatory Commission ND-23-0301 Enclosure Page 3 of 6 Additional hardware and software installation and associated inspections and testing were performed on-site to verify that the cabinets were intact and functional in accordance with Field Change Notifications (FCNs) AP1000 Vogtle Unit 4 PMS Software Installation - Software Release 9.0.0.1 (Reference 7) and PMS Software Installation - Software Release 9.0.0.4 (Reference 8). These FCNs were implemented by work orders listed in ITAAC Technical Report SV4-PMS-Cabinet Software Loading-001 (Reference 9), and B-GEN-ITPCI-001 (Reference 12).
SV4-PMS Cabinet Software Loading-001 (Reference 9) summarizes the software loading. SV4-PMS Cabinet Diagnostic Testing -001 (Reference 13) documents the performance of diagnostic testing, using individual WOs for each cabinet, and verified the diagnostics were satisfactory for each cabinet. References 9 and 13 include steps that confirm and document successful software load and further confirm the physical properties of the as-built PMS. A regression analysis (i.e., change evaluation) was performed for software changes (Reference 10) to determine if additional testing was needed for the as-built system.
The completed Unit 4 FAT, FCNs, regression test results, and diagnostic testing confirm that PMS plant parameters listed in Attachment A with a "Yes" in the "Alert" column are used to generate visual alerts that identify challenges to critical safety functions. These results also confirm that visual alerts actuate in accordance with their correct logic and values.
References 2 through 13 are available for NRC inspection as part of the Unit 4 ITAAC 2.5.02.08a.ii Completion Package (Reference 14).
ITAAC Finding Review In accordance with plant procedures for ITAAC completion, Southern Nuclear Operating Company (SNC) performed a review of all findings pertaining to the subject ITAAC and associated corrective actions. This review found there were no relevant findings associated with this ITAAC. The review is documented in the ITAAC 2.5.02.08a.ii Completion Package (Reference 14) and is available for NRC review.
ITAAC Completion Statement Based on the above information, SNC hereby notifies the NRC that ITAAC 2.5.02.08a.ii was performed for VEGP Unit 4 and that the prescribed acceptance criteria were met.
Systems, structures, and components verified as part of this ITAAC are being maintained in their as-designed, ITAAC compliant condition in accordance with approved plant programs and procedures.
