- 1. Proposed Technical Specification Changes (Mark-Ups) for BFN Units 1, 2, and 3, SQN Units 1 and 2, and WBN Units 1 and 2
1.0
SUMMARY
DESCRIPTION This evaluation supports a request for the Nuclear Regulatory Commission (NRC) to amend Renewed Facility Operating License (RFOL) Nos. DPR-33, DPR-52, and DPR-68 for Browns Ferry Nuclear Plant (BFN), Units 1, 2, and 3; RFOL Nos.
DPR-77 and DPR-79 for Sequoyah Nuclear Plant (SQN), Units 1 and 2; and Facility Operating License (FOL) Nos. NPF-90 and NPF-96 for Watts Bar Nuclear Plant (WBN), Units 1 and 2. The proposed change would revise the RFOLs and FOLs to remove the table of contents (TOC) from the technical specifications (TS). The TOC is not being eliminated, as it will continue to be published with the site-controlled version of the TS. However, following approval of this License Amendment Request (LAR), revisions to the TOC will be made administratively under licensee control, and without NRC review and approval. Additionally, as part of reviewing the TOC for WBN and SQN, two additional administrative changes were identified for WBN Unit 1 and SQN Units 1 and 2 TS.
2.0 DETAILED DESCRIPTION The proposed change would revise the RFOLs and FOLs to remove the TOC from the TS. For purposes of this LAR, the TOC includes other front matter, such as List of Tables, List of Figures, and List of Acronyms, as applicable, in the respective BFN, SQN, and WBN TS.
The TOC for the TS is not being eliminated. Rather, following approval of this LAR, responsibility for maintenance and issuance of updates to the TS TOC will transfer from the NRC to the Tennessee Valley Authority (TVA). The TOC will no longer be included in the NRC issued TS and as such will no longer be part of the TS (Appendix A to the RFOLs and Operating Licenses). A TOC for the TS will be maintained under TVA control, and TOC changes will be issued by TVA in conjunction with the implementation of future NRC-approved TS amendments.
Placing the TOC under licensee control eliminates the regulatory burden of submitting TOC pages for NRC review and allows timely administrative corrections and improvements to the TOC without NRC review and approval.
As part of reviewing the TOCs for this application, it was noted the WBN, Unit 1 TS Page 3.7-1 does not lead with the title 3.7 PLANT SYSTEMS (as shown by the Westinghouse Standard Technical Specifications (NUREG-1431)), and is revised.
This inconsistency has been present on this page since issuance of the License Amendment 19 (ML003691130). It was also noted that the SQN, Unit 1 and 2 TS Pages 3.2.2-1 do not contain parenthesis around the term FH(X,Y) where it is first defined (also as shown by NUREG-1431 for the analogous TS), and is revised. This inconsistency has been present since the issuance of License Amendments 334/327 for SQN, Units 1 and 2, respectively (ML15238B460).
CNL-20-041 E2-6
3.0 TECHNICAL EVALUATION
The TOC does not meet the criteria specified in 10 CFR 50.36 requiring its inclusion within a plant's TS. Specifically, 10 CFR 50.36(b) states:
Each license authorizing operation of a production or utilization facility of a type described in § 50.21 or § 50.22 will include technical specifications. The technical specifications will be derived from the analyses and evaluation included in the safety analysis report, and amendments thereto, submitted pursuant to § 50.34.
Additionally, 10 CFR 50.36(c) states the "Technical specifications will include items in the following categories." Review of 10 CFR 50.36 indicates that a TOC was not listed in the regulation as one of the categories.
The TOC references the page number of each Specification in the TS and does not contain any technical information required by 10 CFR 50.36. Because the TOC does not include information required to be in the TS by 10 CFR 50.36, inclusion of a TOC within the TS is optional. Removal of the TOC from the TS is an administrative change and is acceptable.
Additionally, the "Writer's Guide for Plant-Specific Improved Technical Specifications (Reference 1) was reviewed for guidance. The writer's guide refers to the TOC as "Technical Specification Front Matter," which also includes the Title Page and List of Effective Pages. These portions of the TS are under licensee control, as proposed for the TOC.
The TS TOC will be maintained, revised, and distributed in accordance with TVA administrative procedures. Holders of controlled copies of the TS will continue to receive periodic updates of the TOC pages resulting from approved license amendments.
The addition of 3.7 PLANT SYSTEMS below the header on Page 3.7-1 of the WBN, Unit 1 TS (consistent with Reference 1) is an administrative change. Similarly, adding parenthesis around the term FH(X,Y) to Page 3.2.2-1 of the SQN, Units 1 and 2 TS (where it is first defined) is an administrative change.
4.0 REGULATORY EVALUATION
4.1 Applicable Regulatory Requirements/Criteria The NRC's regulation at Title 10 of the Code of Federal Regulations (10 CFR),
Paragraph 50.36, contains requirements for what is to be included in a licensee's TS.
The Table of Contents, which contains only administrative information, is not required to be in the TS per the requirements of 10 CFR 50.36.
4.2 Precedent A license amendment was issued to the Exelon fleet to remove the TOC from the TS (Reference 2) on December 18, 2019. While this is the most recent precedent, there are numerous others that preceded this.
CNL-20-041 E3-6
4.3 No Significant Hazards Consideration In accordance with the requirements of 10 CFR 50.90, Tennessee Valley Authority (TVA) requests an amendment to remove the table of contents (TOC) from the Technical Specifications (TS) of Browns Ferry Nuclear Plant (BFN), Sequoyah Nuclear Plant (SQN), and Watts Bar Nuclear Plant (WBN) and place it under licensee control. Two associated minor formatting changes are also made to Page 3.7-1 of the WBN, Unit 1 TS to add 3.7 PLANT SYSTEMS below the header, and to Pages 3.2.2-1 of the SQN, Units 1 and 2 TS to add parenthesis around the term FH(X,Y) where it is first defined. TVA has evaluated the proposed amendment in accordance with 10 CFR 50.91 against the standards in 10 CFR 50.92 and has determined that the operation of the facility in accordance with the proposed amendment presents no significant hazards. TVAs evaluation against each of the criteria in 10 CFR 50.92 follows.
- 1. Does the proposed amendment involve a significant increase in the probability or consequences of an accident previously evaluated?
Response: No.
The proposed change is administrative and affects control of a document, the TOC, listing and providing the page number of the specifications in the plant TS.
Transferring control of changes to the TOC to the licensee does not affect the operation, physical configuration, or function of plant equipment or systems. It does not affect the initiators or assumptions of analyzed events; nor does it affect the mitigation of accidents or transient events. The change has no effect on the probability or consequences of an accident.
The formatting changes to the WBN and SQN TS are similarly administrative with no effect on the probability or consequences of an accident.
Therefore, the proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.
- 2. Does the proposed amendment create the possibility of a new or different kind of accident from any accident previously evaluated?
Response: No.
The proposed change to place the TOC under licensee control is administrative and does not alter the plant configuration, require installation of new equipment, alter assumptions about previously analyzed accidents, or affect the operation or function of plant equipment or systems.
The formatting changes to the WBN and SQN TS are similarly administrative with no interface with previously analyzed accidents.
Therefore, the proposed change does not create the possibility of a new or different kind of accident from any accident previously evaluated.
CNL-20-041 E4-6
- 3. Does the proposed amendment involve a significant reduction in a margin of safety?
Response: No.
The proposed change is administrative. The TOC is not required by regulation to be included in the operating license or the attached TS. Transfer of the TOC from NRC control to TVA control does not affect any safety assumptions or have the potential to reduce a margin of safety as described in the TS Bases. No change in the technical content of the TS specifications is involved.
The formatting changes to the WBN and SQN TS are similarly administrative with no effect on any safety margins.
Therefore, the proposed change does not involve a significant reduction in a margin of safety.
Based on the above, TVA concludes that the proposed amendment does not involve a significant hazards consideration under the standards set forth in 10 CFR 50.92(c),
and, accordingly, a finding of no significant hazards consideration is justified.
4.4 Conclusions In conclusion, and based on the considerations discussed above: (1) there is reasonable assurance that the health and safety of the public will not be endangered by the removal of the TS TOC, and the WBN and SQN TS formatting changes; (2) the changes will be in compliance with NRC regulations; and (3) the issuance of the amendments will not be inimical to the common defense and security or to the health and safety of the public.
5.0 ENVIRONMENTAL CONSIDERATION
TVA has determined that the proposed amendment does not change any requirements with respect to installation or use of a facility component located within the restricted area, as defined in 10 CFR 20, or would change an inspection or surveillance requirement. The proposed amendment does not involve (i) a significant hazards consideration, or (ii) a significant change in the types or significant increase in the amounts of any effluent that may be released offsite, or (iii) a significant increase in individual or cumulative occupational radiation exposure. Accordingly, the proposed amendment meets the eligibility criterion for a categorical exclusion set forth in 10 CFR 51.22(c)(9). Therefore, TVA concludes pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the proposed amendment.
