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 C.2.6.09.03a [Index Number 660]
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 C.2.6.09.03a [Index Number 660]. This ITAAC confirms that isolation zones exist in outdoor areas adjacent to the physical barrier at the perimeter of the protected area and allow 20 feet of observation and assessment of the activities of people on either side of the barrier. 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.
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-23-0115 Enclosure Page 2 of 3 ITAAC Statement Design Commitment 3.a) Isolation zones exist in outdoor areas adjacent to the physical barrier at the perimeter of the protected area that allows 20 feet of observation on either side of the barrier. Where permanent buildings do not allow a 20-foot observation distance on the inside of the protected area, the building walls are immediately adjacent to, or an integral part of, the protected area barrier.
Inspections/Tests/Analyses Inspections will be performed of the isolation zones in outdoor areas adjacent to the physical barrier at the perimeter of the protected area.
Acceptance Criteria Isolation zones exist in outdoor areas adjacent to the physical barrier at the perimeter of the protected area and allow 20 feet of observation and assessment of the activities of people on either side of the barrier. Where permanent buildings do not allow a 20-foot observation and assessment distance on the inside of the protected area, the building walls are immediately adjacent to, or an integral part of, the protected area barrier and the 20-foot observation and assessment distance does not apply.
ITAAC Determination Basis An inspection of the isolation zones in outdoor areas adjacent to the physical barrier at the perimeter of the protected area was performed to verify that isolation zones exist in outdoor areas adjacent to the physical barrier at the perimeter of the protected area and allow 20 feet of observation and assessment of the activities of people on either side of the barrier and satisfy the applicable protected area perimeter physical barrier isolation zone requirements of the VEGP Unit 1-4 Physical Security Plan associated with 10 CFR 73.55(e)(7)(i)(A). The VEGP Unit 4 Plant Security System ITAACs only cover the Unit 4 plant security system design commitment scope.
Where permanent buildings do not allow a 20-foot observation and assessment distance on the inside of the protected area, the building walls are immediately adjacent to, or an integral part of, the protected area barrier and the 20-foot observation and assessment distance does not apply. In the case of VEGP Unit 4 there are no permanent buildings that are immediately adjacent to, or an integral part of, the protected area barrier.
An inspection was performed as described in ITAAC Technical Report SV4-SES-ITR-800660 (Reference 1) and measured, using a commercially available measuring device, the isolation zone observation and assessment distance in outdoor areas that are adjacent to either side of the protected area perimeter physical barrier. The measurements verified that a minimum 20-foot observation and assessment distance exists on either side of the protected area perimeter physical barrier. The inspection also visually confirmed that the isolation zone observation and assessment distances measured above are clear of objects which could conceal or shield the activities of people on either side of the protected area perimeter physical barrier.
The results of the inspection are documented in Reference 1 and verify that isolation zones exist in outdoor areas adjacent to the physical barrier at the perimeter of the protected area and allow 20 feet of observation and assessment of the activities of people on either side of the barrier.
