1.0 INTRODUCTION

By application dated September 28, 2020 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML20273A290), Energy Harbor Nuclear Corporation (Energy Harbor, the licensee) submitted a request to use a specific provision of a later edition of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel (B&PV) Code,Section XI, for Davis-Besse Nuclear Power Station, Unit No. 1 (DBNPS), Perry Nuclear Power Plant, Unit No. 1 (PNPP), and Beaver Valley Power Station, Unit Nos. 1 and 2 (BVPS).

Specifically, pursuant to Title 10 of the Code of Federal Regulations (10 CFR) 50.55a(g)(4)(iv),

Energy Harbor proposed to use subparagraph IWA-4540(b) of the 2017 Edition of the ASME BPV Code,Section XI, in place of the corresponding subparagraph from the code of record at these facilities.

Enclosure

2.0 PROPOSED USE OF SUBSEQUENT CODE EDITION AND ADDENDA 2.1 Components for Which the Subsequent Code Edition is Requested All Class 1, 2, and 3 items located in the ASME BPV Code,Section XI, boundaries.

2.2 Current Code Requirement Subparagraph IWA-4540(b) provides items that are exempt from pressure testing after repair/replacement activities.

2.3 Current Code Edition and Addenda of Record The application identified the currently applicable editions and addenda of the ASME BPV Code,Section XI, for each plant, as shown in Table 1 below. In addition, Table 1 shows the associated 10-year inservice inspection (ISI) interval, including the start and end dates, for each plant.

Table 1: Current ASME BPV Code,Section XI, Code of Record ISI ASME BPV CODE, PLANT START END INTERVAL SECTION XI Beaver Valley Power 2013 Edition, No 5th 8/29/2018 8/28/2028 Station, Unit No. 1 Addenda Beaver Valley Power 2013 Edition, No 4th 11/5/2018 8/28/2028 Station, Unit No. 2 Addenda Davis-Besse Nuclear 2007 Edition, through Power Station, Unit 4th 9/21/2012 9/20/2022 2008 Addenda No. 1 Perry Nuclear Power 2013 Edition, No 4th 5/18/2019 5/17/2029 Plant, Unit No.1 Addenda 2.4 Proposed Subsequent Code Edition and Addenda The proposed subsequent Code edition and addenda to be used is subparagraph IWA-4540(b) of the 2017 Edition of the ASME BPV Code,Section XI.

2.5 Duration of the Use of the Later Code Edition and Addenda The duration of this request is for the remainder of the current 10-year ISI interval for each plant, as shown in Table 1 above.

3.0 REGULATORY EVALUATION

The licensee is proposing to use a portion of a later edition and addenda of the ASME BPV Code,Section XI, in accordance with 10 CFR 50.55a(g)(4)(iv), which states:

Inservice examination of components and system pressure tests may meet the requirements set forth in subsequent editions and addenda that are incorporated by reference in paragraph (a) of this section, subject to the conditions listed in

paragraph (b) of this section, and subject to Commission approval. Portions of editions or addenda may be used, provided that all related requirements of the respective editions or addenda are met.

Given that 10 CFR 50.55(g)(4)(iv) permits the NRC staff to approve the use of subsequent editions and addenda of the ASME BPV Code,Section XI, the NRC staff finds that, subject to the following technical evaluation, the licensee may propose to use a portion of a later edition and addenda of the ASME BPV Code,Section XI, and the NRC staff has the regulatory authority to approve the use of a portion of a later edition and addenda of the ASME BPV Code,Section XI.

4.0 NRC TECHNICAL EVALUATION As previously stated in Section 3.0 of this safety evaluation, prior to approving the use of a subsequent edition and addenda of the ASME BPV Code under 10 CFR 50.55a(g)(4)(iv), the NRC staff must find that: (1) the proposed subsequent edition and addenda are incorporated by reference in 10 CFR 50.55a(a); (2) the licensee will comply with the conditions listed in 10 CFR 50.55a(b) that are applicable to the proposed edition and addenda of the ASME BPV Code; (3) the licensee requested approval to use the subsequent edition and addenda; and (4) if only portions of edition or addenda are to be used, all related requirements of the respective edition or addenda are met. If these criteria are met, the NRC staff can find the use of the subsequent edition and addenda of the ASME BPV Code,Section XI, to be acceptable.

4.1 Incorporation by Reference In evaluating the first criterion, 10 CFR 50.55a(b)(2) incorporates by reference the ASME BPV Code, 2017 Edition,Section XI, Division 1, as approved in Federal Register Notice, 85 FR 26540, dated May 4, 2020. The licensee proposed to use the 2017 Edition of Section XI, which is included in the list of editions and addenda incorporated by reference in the current edition of 10 CFR 50.55a(a). Therefore, the NRC finds that the first criterion has been satisfied.

4.2 Subject to Conditions Listed in 10 CFR 50.55a(b)

In evaluating the second criterion, the NRC staff finds that 10 CFR 50.55a(b) contains no conditions relevant to this request. Therefore, the NRC staff finds that the second criterion has been satisfied.

4.3 Requesting Commission Approval In evaluating the third criterion, the licensees request dated September 28, 2020, constitutes a request to the Commission for approval to use a subsequent edition or addendum of the ASME BPV Code. Therefore, the NRC staff finds that the third criterion has been satisfied.

4.4 All Related Requirements In evaluating the fourth criterion, the NRC staff finds that there are no related requirements relevant to this request. Therefore, the NRC staff finds that the fourth criterion has been satisfied.

4.5 Summary Based on the above evaluation, the NRC staff finds that the licensee has adequately addressed all regulatory requirements set forth in 10 CFR 50.55a(g)(4)(iv).

5.0 CONCLUSION

As set forth above, the NRC staff finds that the licensee has adequately addressed all of the regulatory requirements set forth in 10 CFR 50.55a(g)(4)(iv). Therefore, the NRC staff finds that the use of subparagraph IWA-4540(b) of the 2017 Edition of the ASME BPV Code,Section XI, is acceptable. The NRC staff approves the use of subparagraph IWA-4540(b) of the 2017 Edition of the ASME BPV Code,Section XI, at Davis-Besse Nuclear Power Station, Unit No. 1, Perry Nuclear Power Plant, Unit No. 1, and Beaver Valley Power Station, Unit Nos. 1 and 2.

For each facility, this approval is for the remainder of the current 10-year ISI interval, as listed in Table 1 above.

All other ASME BPV Code,Section XI, requirements which are not modified by the NRC staffs approval of the licensees request remain applicable, including third-party review by the Authorized Nuclear Inservice Inspector.
