DPR-33, DPR-52, and DPR-68 NRC Docket Nos. 50-259, 50-260, and 50-296

Subject:

Browns Ferry Nuclear Plant, Units 1, 2, and 3 - Request to Use a Portion of a Later Edition of the ASME Operation and Maintenance of Nuclear Power Plants

Reference:

NRC Regulatory Issue Summary 2004-12, "Clarification on Use of Later Editions and Addenda to the ASME OM Code and Section XI," dated July 28, 2004 In accordance with Title 10 of the Code of Federal Regulations, Section 50.55a, Codes and standards, paragraph (f)(4)(iv), the enclosure to this submittal contains the Tennessee Valley Authority (TVA) request for use of a portion of the American Society of Mechanical Engineers (ASME) Operation and Maintenance of Nuclear Power Plants (OM), 2017 Edition, to supplement the 2004 Edition through 2006 Addenda for the Browns Ferry Nuclear Plant (BFN),

Units 1, 2, and 3.

Specifically, TVA requests to use the 2017 Edition, ISTA-2000 definition of refueling outage.

refueling outage: applies to the normally scheduled once-per-cycle outage period in which the refueling mode, as defined by plant technical specifications, is entered.

TVA is requesting to use the definition of refueling outage from ASME OM, 2017 Edition, ISTA-2000, to clarify that the requirements of ASME OM, 2004 Edition through 2006 Addenda, ISTC-3521, Category A and B Valves, subparagraphs (e) and (h) as well as ISTC-3522, Category C Check Valves, subparagraphs (c) and (f) are only applicable to the normally scheduled once-per-cycle outage period. Requirements of the referenced ISTC paragraphs are essentially the same between the 2004 Edition through 2006 Addenda and the 2017 Edition.

U.S. Nuclear Regulatory Commission CNL-22-013 Page 2 January 6, 2022 This request is being made for the fourth ten-year inservice testing interval for BFN Units 1, 2, and 3. The applicable ASME OM Code of Record for the fourth interval is the 2004 Edition through 2006 Addenda for each unit. The fourth ten-year interval for BFN Units 1, 2, and 3 began on January 1, 2013 and is scheduled to end on August 30, 2022.

As stated in the Reference, Regulatory Information Summary 2004-12, The request to use a later edition and addenda is not a relief request; it is simply a request to use a later Code....The amount of written documentation needed for a request to use a later Code edition and addenda is significantly less than for a relief request or a request to use an alternative requirement.

If portions of a later Code edition and addenda are used, licensees must assure that all related requirements of the respective editions and addenda are met. A discussion of the related requirements should be included in the letter to the NRC. The regulations do not specify when the letter must be submitted, only that it be submitted before using the proposed later Code edition and addenda.

There are no related requirements associated with the proposed later Code edition for consideration associated with this request.

TVA requests approval of this request by January 14, 2022, to support an upcoming BFN Unit 1 outage.

There are no new regulatory commitments contained in this letter. If you have any questions regarding this submittal, please contact Kimberly D. Hulvey, Senior Manager, Fleet Licensing at 423-751-3275.

Respectfully, James T. Polickoski Director, Nuclear Regulatory Affairs
