NORTH ANNA POWER STATION UNITS 1 AND 2 RESPONSE TO REQUEST FOR ADDITIONAL INFORMATION PROPOSED LICENSE AMENDMENT REQUEST FOR SPENT FUEL STORAGE AND NEW FUEL STORAGE (CAC Nos. MF9712 AND MF9713)
By letter dated May 2, 2017, Dominion submitted a license amendment request (LAR) to revise Technical Specifications {TS) 3.7.18, "Spent Fuel Pool Storage" and TS 4.3.1 "Criticality." Conforming changes were proposed to Technical Specifications Bases (TSB) 83.7.18.
In an email dated December 21, 2017, the NRC transmitted a request for additional information (RAI) related to the LAR. A January 31, 2018 response date was requested.
The response to the RAI is provided in Attachment 1. Attachment 2 provides a revised marked-up change to TS 4.3.1.1 and Attachment 3 provides the proposed change page forTS4.3.1.1.
Should you have any questions in regard to this submittal, please contact Diane E. Aitken at (804) 273-2694.

Serial No. 16-3838 Docket Nos.: 50-338/339 Attachment 1 RESPONSE TO REQUEST FOR ADDITIONAL INFORMATION VIRGINIA ELECTRIC AND POWER COMPANY (DOMINION ENERGY VIRGINIA)
NORTH ANNA POWER STATION UNITS 1 AND 2
Serial No. 16-3838 Docket Nos.: 50-338/339 Attachment 1 Page 1 of 1 Technical Basis for the Request Section 2.2 of Attachment 1 of the LAR provides a description of the changes to TS 4.3.1.1. Attachment 2 of the LAR provides marked up technical specification pages showing the proposed changes, including TS page 4.0-2, which shows the proposed deletion of the text identifying a specific document providing the methodology used to calculate uncertainties in keff, in both TS 4.3.1.1.b. and c. Section 2.2 of Attachment 1 does not describe the basis for the proposed deletions of text.
NUREG-1431 contains the staff's guidance on one manner of format and content for TSs that would meet the regulatory requirements of 10 CFR 50.36. The current NAPS TS 4.3.1.1 and NUREG-1431 both cite the location of the methodologies used to calculate uncertainties in keff* It appears the LAR is proposing deletion of the location of the methodologies used to calculate uncertainties in keff in TS 4.3.1.1 without fully describing why the deletion is appropriate for NAPS.
RAI Please provide a full description and justification for the proposed deletion of the location of the methodology used to calculate uncertainties in keff in TS 4.3.1.1, or, alternatively, provide a revised change to TS 4.3.1.1 that retains the citation of the location of the methodology used to calculate uncertainties in keff*
RAI Response As indicated in the request for additional information (RAI), the license amendment request (LAR) submitted May 2, 2017, proposed the deletion of text identifying a specific document providing the methodology used to calculate uncertainties in keff, in both Technical Specification (TS) 4.3.1.1.b. and c without describing why the change was appropriate. The specific document cited in the current TS 4.3.1.1 as providing the methodology used to calculate uncertainties in keff is the LAR letter describing the analysis that was reviewed by the NRC prior to approval of the current TS 4.3.1.1.
Deletion of this text was appropriate since the cited LAR letter was obsolete (superseded by the methodology provided in the LAR submittal dated May 2, 2017).
Guidance in NUREG-1431, Standard Technical Specifications - Westinghouse Plants, Volume 1, Specifications, indicates it is appropriate to include a reference to the Final Safety Analysis Report (FSAR) as the location of the methodology used to calculate uncertainties in keff in TS 4.3.1.1. Updated Final Safety Analysis Report (UFSAR)
Section 9.1 will be revised to include the methodology used to calculate uncertainties in keff during implementation of the approved LAR. Therefore, a mark-up of Technical Specification 4.3.1.1 that adds UFSAR Section 9.1 as the location of the methodology used to calculate uncertainties in keff is provided in Attachment 2. The associated proposed change to Technical Specification 4.3.1.1 is provided in Attachment 3.
