Duke Energy Letter, "Revision to Tornado/HELB Mitigation Strategies and Regulatory Commitments 8T, lOT, 17T, and 25H," dated December 19, 2013.Duke Energy's initial commitments related to tornado mitigation strategies are documented in a November 30, 2006 submittal (Ref. 1). These commitments were most recently updated in a Duke Energy submittal dated December 19, 2013 (Ref. 4). This letter is Duke Energy's notification of a needed revision to Tornado Commitment 17T of the Reference 4 letter.This letter revises Tornado Commitment 17T, which is a modification to improve the protection for a set of double doors on the SSF. The commitment was to complete the modification by January 31, 2015. A design was conceived, and specific design criteria was developed; however, upon moving toward implementation the design was determined to be neither feasible nor constructible.
Insufficient time remains to develop and implement a new design prior to the committed due date.A commitment change is necessary to allow time for the development of a new design strategy to provide the necessary door protection.
The 17T commitment has been revised with a due date of September 30, 2015 to provide an implementation completion date for the new modification.
The revision is indicated on Enclosure 1 of this letter, which is a complete list of tornado commitments.
In accordance with Tornado Commitment 1OT, Duke Energy has verbally notified Louise Lund, NRC Deputy Director, Division of Reactor Licensing of this commitment change via telephone on December 19, 2014. A olI www.duke-energy.com , &--
ONS-2014-164 Page 2 Revision to Tornado Commitment 17T December 19, 2014 Duke Energy remains resolved to complete the tornado mitigation commitments and values the risk benefit it will provide for the station.If you have any questions in regard to this letter, please contact Stephen C.

The supplier is capable of supplying a quality product.* The quality of the item can be reasonably assured.Duke Energy will utilize technical procedures to control testing of concrete substrate and installation and inspection of the FRP system in accordance 26T with ICC AC125 [Approved 10/2006, Effective 1/1/2007], ACI 440.2R-02 Y[Effective 7/1/2002], and ICC AC1 78 [Approved 6/2003, Effective 7/1/2003, editorially revised 6/2008].1 Tornado commitments 20-23 originate from the FRP LAR dated 6-1-2006 (NRC SER dated 2-21-2008).
2 Tornado commitments 20-26 are addressed in the NRC's FRP SER for brick masonry dated 6-27-2011.
Enclosure 1 -Revised Tornado and HELB Regulatory Commitments December 19, 2014 Page 3 No. Tornado Commitments Due Date C (YIN)Duke Energy will implement a long-term inspection program of the FRP system that will be described in UFSAR Section 18.3.13 and EDM-410, meet the requirements of ICC AC125 [Approved 10/2006, Effective 1/1/2007], ACI 440.2R-02
[Effective 7/1/2002], and ICC AC178 [Approved 6/2003, Effective 7/1/2003, editorially revised 6/2008], on the following schedule:
at each unit's outage cycle for the first six years from 2012 through 2017, then, if justified based on no observed FRP degradation, transition to every-other outage cycle for the next four years from 2018 through 2021, then, if justified based on continued no observed FRP degradation, transition to every third outage cycle thereafter from 2022 until end of license in July 2034. Inspections of the installed FRP system will include:* visual inspections of test walls and portions (both random and controlled locations) of WPR in-service walls for changes in color, debonding, peeling, blistering, cracking, 27T
- crazing, deflections and other anomalies; 2 tension adhesion testing of cored samples taken from designated test walls using methods specified in ASTM D7234; and,* visual inspections of mortar joints located along the bottom edge of FRP-strengthened masonry walls.For each inspection interval, the portions of FRP-strengthened masonry walls to be inspected will be chosen in accordance with a sampling plan developed from guidance provided by a) Draft Regulatory Guide DG-1070, "Sampling Plans Used for Dedicating Simple Metallic Commercial Grade Items for use in Nuclear Power Plants", and b) EPRI NP-7218 document "Guidelines for the Utilization of Sampling Plans for Commercial Grade Item Acceptance" (NCIG-19), as implemented at ONS by Supply Chain Directive SCD-290 [(new) Reference 21 of Enclosure 2].Note: This response replaces the five (5) year inspection commitment made in FRP LAR (No. 2009-05) dated June 29, 2009, and will apply to the FRP application for both block and brick.Duke Energy will install mechanical shear restraints along the brick 28T masonry wall perimeter (top and sides only) and block masonry wall y perimeter (top only) to remediate potentially limiting conditions of construction.
Duke Energy will incorporate the FRP testing and inspection program into 29T Oconee Nuclear Station's Aging Management Program.As discussed with the Staff, Fyfe Company, LLC, the manufacturer of the 30T FRP products, will provide Duke Energy with a Certificate of Compliance y certifying that both the FRP product and its installation meet all applicable requirements.
