RA-20-0191 Attachment Page 2 of 3 Pursuant to 10 CFR 50.55a(g)(4)(iv) and in accordance with the guidance provided in NRC Regulatory Issue Summary (RIS) 2004-12, dated July 28, 2004, Duke Energy Carolinas, LLC and Duke Energy Progress, LLC, requests NRC approval to use specific provisions of a later edition of the American Society of Mechanical Engineers (ASME)

Boiler and Pressure Vessel (B&PV) Code, Section XI, for Duke Energy Nuclear Fleet.

Specifically, Duke Energy requests approval to use the ASME Boiler and Pressure Vessel Code, Section XI, 2017 Edition, Articles IWA-5120, IWA-5213, IWA-5241, IWA-5242, and IWA-5250 for pressure testing of Class 1, Class 2, and Class 3 systems.

1. ASME Code Component(s) Affected:

All pressure-retaining components subject to pressure testing requirements of Examination Category B-P for Class 1, Category C-H for Class 2, and Category D-B for Class 3.

2. Applicable Code Edition and Addenda

The applicable Edition and Addenda of the ASME Code, Section XI is identified in Table 1.

Table 1 ISI ASME Section XI Code Plant/Unit(s) Interval Start Date Interval End Date1 Interval Edition/Addenda Brunswick Steam Fifth 2007 Edition, Through 2008 05/11/2018 05/10/2028 Electric Plant Units 1 Addendum and 2 Catawba Nuclear Fourth 2007 Edition, Through 2008 08/19/2015 12/06/2024 (Unit 1)

Station Units 1 and 2 Addendum 02/24/2026 (Unit 2)

Station Units 1 and 2 Addendum 07/15/2014 (Unit 2) 02/29/2024 (Unit 2)

Oconee Nuclear Station Fifth 2007 Edition, Through 2008 07/15/2014 07/15/2024 Units 1, 2, and 3 Addendum Shearon Harris Nuclear Fourth 2007 Edition, Through 2008 09/09/2017 09/08/2027 Power Plant Unit 1 Addendum Note 1: Date listed is the currently planned interval end date. In accordance with IWA-2430(c)(1),

this end date may be extended or shortened as necessary.

3. Proposed Subsequent Code Edition and Addenda (or Portion):

Duke Energy proposes to utilize portions of the ASME Section XI, 2017 Edition in lieu of the 2007 Edition up to and including the 2008 Addenda. Until the 2017 Edition was published, the ASME Section XI code did not contain requirements for pressure testing pneumatic safety related systems. Additionally, the 2017 edition provides exemptions for periodic system pressure tests, clarification for test condition hold time, and incorporates clarification for systems borated for the purpose of controlling reactivity. The affected ASME Section XI Examination Categories are B-P for Class 1, C-H for Class 2, and D-B for Class 3.

4. Related Requirements:

10 CFR 50.55a(g)(4)(iv) 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."

Federal Register, Volume 85, Number 86, dated May 4, 2020 (85 FR 26540),

incorporates by reference the 2015 and 2017 Editions of the ASME Code for inservice inspection. Duke Energy will adhere to any conditions that apply to pressure testing.

5. Duration of Proposed Request:

The duration of this approval will continue for the remainder of the current inservice inspection interval's listed in Table 1.
