Ladies and Gentlemen:

In accordance with1 O 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 3 Inspections, Tests, Analyses , and Acceptance Criteria (ITAAC) Item 3.5.00.06 (Index Number 831].

This ITAAC verified that the safety-related displays identified in Combined License (COL), Appendix C, Table 3.5-1 can be retrieved in the Main Control Room (MCR) and that each of the process, effluent, airborne, and area radiation monitors listed in Tables 3.5-2 through 3.5-5 exist in the locations identified in Table 3.5-7. The closure process for this ITAAC is based on the guidance described in Nuclear Energy Institute (NEI) 08-01, Industry Guideline for the ITAAC Closure Process Under 10 CFR Part 52, which was 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.

ITAAC Determination Basis Inspections were performed to verify the retrievability of the Vogtle Electric Generating Plant (VEGP) Unit 3 Radiation Monitoring safety-related displays in the main control room (MCR), as identified in Combined License (COL) Appendix C Table 3.5-1 (Attachment A) , and that the process radiation monitors, effluent radiation monitors, airborne radiation monitors, and area radiation monitors listed in Tables 3.5-2 (Attachment B) through 3.5-5 (Attachment E) exist and are in the locations identified in Table 3.5-7 (Attachment B through Attachment E).

U.S. Nuclear Regulatory Commission ND-21-0057 Enclosure Page 3 of 10 Safety-related displays identified in Table 3.5-1 can be retrieved in the MCR.

The inspection was performed in accordance with the Unit 3 component test package work order, as documented in Reference 1, for radiation monitor component indication verifications, and visually confirmed that when each of the safety-related displays identified in Attachment A was summoned at the MCR Protection and Safety Monitoring System (PMS) Visual Display Units (VDUs), the summoned safety-related display appeared on the PMS VDU .

Attachment A Note (1) states that each MCR Radiation Monitoring Package (VBS-JS01 A and VBS-JS01 B) includes particulate, iodine, and gaseous radiation monitors, so these displays were inspected individually.

The inspection confirmed that the safety-related displays of the parameters identified in COL Appendix C Table 3.5-1 can be retrieved in the MCR.

Walkdown inspections of the as-built radiation monitoring equipment were conducted after completion of construction to confirm that the area radiation monitors listed in Attachment E exist in the locations indicated in Attachment E. Inspections were performed , as documented in Reference 2, which involved visual obse rvations of the area radiation monitors and verification that the monitors are installed in their specified locations. The make and model and other nameplate data of the monitors were also inspected and compared to that specified in design documents to verify that the installed radiation monitors have the appropriate nominal detection ranges to provide indication of unusual radiological events.

The inspections confirmed that the area radiation monitors listed in COL Appendix C Table 3.5-5 exist and are present in the component locations listed in COL Appendix C Table 3.5-7.

Together, these inspections, tests , and reports (References 1 and 2) confirm that the ITAAC Acceptance Criteria requirements are met:
