S. Nuclear Regulatory Commission ATTN: Document Control Desk Washington, D. C. 20555-0001 Southern Nuclear Operating Company Joseph M. Farley Nuclear Plant - Units 1 and 2 Edwin I. Hatch Nuclear Plant - Units 1 and 2 Vogtle Electric Generating Plant - Units 1 and 2 Second Supplement to License Amendment Request to Revise Technical Specification 5.7, High Radiation Area, Administrative Controls Ladies and Gentlemen:
On March 25, 2021 (ADAMS Accession Number ML21084A003), pursuant to the provisions of Section 50.90 of Title 10 of the Code of Federal Regulations, Southern Nuclear Operating Company (SNC) requested amendments to the Technical Specifications (TS) for Joseph M.
Farley Nuclear Plant (FNP), Units 1 and 2, Edwin I. Hatch Nuclear Plant (HNP), Units 1 and 2, and Vogtle Electric Generating Plant (VEGP), Units 1 and 2. The proposed amendments would revise TS 5.0, Administrative Controls, specifically, TS 5.7, High Radiation Area, to align with the Standard Technical Specifications in NUREG-1431, Standard Technical Specifications -
Westinghouse Plants, Revision 4.0, and NUREG-1433, Standard Technical Specifications -
General Electric BWR/4 Plants, Revision 4.0, as applicable.
SNC supplemented the original request via letter dated June 30, 2021 (ADAMS Accession Number ML21181A390). This supplement provides associated marked-up TS pages as requested by the Nuclear Regulatory Commission.
Attachments 1a, 1b, and 1c provide marked-up TS pages for FNP, HNP, and VEGP, respectively, consistent with the clean-typed pages in the June 30, 2021 supplement. The marked-up pages replace those in the original request of March 25, 2021.
SNC requests the same approval and implementation schedule as requested in its original application. The conclusions of the No Significant Hazards Consideration Determination and Environmental Consideration contained in the original application have been reviewed and are unaffected by this supplement.
This letter contains no regulatory commitments.
U. S. Nuclear Regulatory Commission NL-21-0984 Page 2 In accordance with 10 CFR 50.91, SNC is notifying the State of Alabama and the State of Georgia of this supplement to the license amendment request by transmitting a copy of this letter and enclosure to the designated State Officials.
If you have any questions, please contact Ryan Joyce at 205-992-6468.
I declare under penalty of perjury that the foregoing is true and correct. Executed on the 10th day of November 2021.

Each entryway to such an area shall be barricaded and conspicuously posted as a high radiation area. Such barricades may be opened as necessary to permit entry or exit of personnel or equipment.
- b.
Access to, and activities in, each such area shall be controlled by means of Radiation Work Permit (RWP) or equivalent that includes specification of radiation dose rates in the immediate work area(s) and other appropriate radiation protection equipment and measures.
- c.
Individuals qualified in radiation protection procedures and personnel continuously escorted by such individuals may be exempted from the requirement for an RWP or equivalent while performing their assigned duties provided that they are otherwise following plant radiation protection procedures for entry to, exit from, and work in such areas.
- d.
Each individual or group entering such an area shall possess:
- 1.
A radiation monitoring device that continuously displays radiation dose rates in the area, or
- 2.
A radiation monitoring device that continuously integrates the radiation dose rates in the area and alarms when the devices dose alarm setpoint is reached, with an appropriate alarm setpoint, or
- 3.
A radiation monitoring device that continuously transmits dose rate and cumulative dose information to a remote receiver monitored by radiation protection personnel responsible for controlling personnel radiation exposure within the area, or
- 4.
A self-reading dosimeter (e.g., pocket ionization chamber or electronic dosimeter), and (i)
Be under the surveillance, as specified in the RWP or equivalent, while in the area, of an individual qualified in radiation protection procedures, equipped with a radiation monitoring device that continuously displays radiation dose rates in the area; who is responsible for controlling personnel exposure within the area, or a to NL-21-0984 FNP Proposed Technical Specification Changes (Mark-Up)

(ii) Be under the surveillance as specified in the RWP or equivalent, while in the area, by means of closed circuit television, of personnel qualified in radiation protection procedures, responsible for controlling personnel radiation exposure in the area, and with the means to communicate with individuals in the area who are covered by such surveillance.
- e.
Except for individuals qualified in radiation protection procedures, or personnel continuously escorted by such individuals, entry into such areas shall be made only after dose rates in the area have been determined and entry personnel are knowledgeable of them. These continuously escorted personnel will receive a pre-job briefing prior to entry into such areas.
