NORTH ANNA POWER STATION, UNITS 1 AND 2

SURRY POWER STATION, UNITS 1 AND 2

DOCKET NOS. 50-338, 50-339, 50-424, AND 50-425

By application dated November 7, 2022 (Agencywide Documents Access and Management System Accession No. ML22312A550), Virginia Electric and Power Company (Dominion Energy Virginia or the licensee) submitted a license amendment request (LAR) for Commission review and approval of the North Anna Power Station, Units 1 and 2 (NAPS), and the Surry Power Station, Units 1 and 2 (SPS), Emergency Plans. The licensees LAR proposes changes to the NAPS and SPS Emergency Plans pursuant to Section 50.54(q) of Title 10 of the Code of Federal Regulations (10 CFR).

The following additional information is needed for the NRC to complete its review.

RAI-1 (a and b)

Issue 1.a: As stated in Section 3.2.2.C, Emergency Direction and Control (Command and Control, Emergency Classification) of Enclosure 1, North Anna Power Station, Units 1 and 2:

Discussion and Assessment of Proposed Changes, and Enclosure 2, Surry Power Station, Units 1 and 2: Discussion and Assessment of Proposed Changes, states in part,

On-shift staffing for Senior Reactor Operators (SROs) includes a third SRO who is SM [Shift Manager]/SEM [Station Emergency Manager] qualified. This individual is not included in the 10 CFR 50.54(m)(2)(i) requirement and is a resource continuously available for oversight and direction of emergency response.

This statement is consistent with Table 5.1, Minimum Staffing Requirements for Emergencies, of the emergency plans for North Anna and Surry which indicate that two Unit Shift Supervisors will be available to provide oversight and an additional Shift Manager will be available to perform classification. In its application, Dominion Energy Virginia is proposing to have three individuals qualified as shift manager/station emergency manager on shift. This does not appear to be consistent with Section 5.0, Organizational Control of Emergencies, of each sites respective Emergency Plan which states, the Shift Manager or Unit Supervisor initially acts in the capacity of the Station Emergency Manager (SEM) and takes actions as outlined in the EPIPS

[emergency plan implementation procedures]. The guidance of NUREG-0654 Table B-1, Emergency Response Organization (ERO) Staffing and Augmentation Plan, states that there should be one Operations Shift Manager who provides overall ERO command and control and emergency action level (EAL) classification.

RAI-1.a: Provide a description of the specific ERO responsibilities for each of the SROs included on Table 5.1 of the North Anna and Surry emergency plans. In your description, describe who provides overall ERO command and control and EAL classification.
