UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001

September 11, 2015 MEMORANDUM TO: Edwin M. Hackett, Executive Director Advisory Committee on Reactor Safeguards FROM: Christopher G. Miller, Director /RA by JMarshall for/ Division of License Renewal Office of Nuclear Reactor Regulation

SUBJECT:

ADVISORY COMMITTEE ON REACTOR SAFEGUARDS REVIEW OF THE BYRON-BRAIDWOOD NUCLEAR STATIONS LICENSE RENEWAL APPLICATION - CORRECTIONS TO THE TABLE OF AGING MANAGEMENT PROGRAMS FOR THE SAFETY EVALUATION REPORT

During the ACRS full committee review for the Byron Station, Units 1 and 2, and Braidwood Station, Units 1 and 2, license renewal application (LRA) on September 10, 2015, the staff indicated that corrections had been identified for Table 3.0-1, "Byron and Braidwood Aging Management Programs," in the staff's "Safety Evaluation, Related to the License Renewal of Byron Station, Units 1 and 2, and Braidwood Station, Units 1 and 2" Safety Evaluation Report (SER) (ADAMS Accession No. ML15182A051). The purpose of this memorandum is to describe those changes in the table that will be incorporated in the NUREG version of the SER. The staff identified three cases of aging management program (AMP) summaries in the table where corrections need to be made; these are shown in the red-line/strikeout version of the Table in Enclosure 1. Specifically:

  • The Water Chemistry AMP is changed in the "SER Section (Disposition)" column (column 6) to "Consistent with exception," as opposed to stating "Consistent."
  • The Flux Thimble Tube Inspection AMP is changed in "LRA Initial Comparison to the GALL Report" (column 4) to "Consistent," as opposed to "Consistent with exception and enhancements."
  • The Environmental Qualification (EQ) of Electric Components AMP is changed in the "SER Section (Disposition)" column (column 6) to "consistent with enhancement" as opposed to "Consistent."

CONTACT: John Daily, NRR/DLR 301-415-3873 These summary designations in the Enclosure have been reviewed against the corresponding SER sections and verified that these accurately reflect the staff's evaluations. These corrections to Table 3.0-1 will be incorporated into the NUREG version of the SER, which also will include the ACRS letter. This NUREG will be prepared and published after the ACRS letter has been issued.

The staff also presented a table showing a summary of the AMPs reflecting which ones were evaluated by the staff as "consistent," "consistent with exceptions," "consistent with enhancements," and "consistent with enhancements and exceptions." The following table is provided to clarify the staff dispositions of the AMPs for each station:

Total AMPs in SER Staff's Disposition Byron AMPs Braidwood AMPs New 13 New Programs 13 New Programs Consistent 11 10 (Fuse Holders AMP is N/A for Braidwood) Consistent with exceptions 2 2 Existing 32 Existing Programs 32 Existing Programs Consistent 5 (Includes Flux Thimble Tube Inspection AMP for Byron)4 Consistent with enhancements 20 20 Consistent with exceptions 1 1 Consistent with enhancements and exceptions 6 7 (Includes Flux Thimble Tube Inspection AMP for Braidwood) 45 Total AMPs 45 AMPs 44 AMPs A disposition of a program as "consistent" means that it is consistent with the GALL Report (Revision 2), as amended by approved Interim Staff Guidance (ISGs). An "enhancement" is an addition to an existing program to bring it into consistency with the GALL Report (as amended by ISGs). An "exception" is a portion of a GALL Report recommendation (as amended by ISGs) that the applicant does not intend to implement. These are evaluated for acceptability by the staff.

The Electrical Fuse holders AMP is a new program, and is applicable only to Byron. Braidwood does not have any components to be managed by this AMP. Therefore, Byron has 45 total applicable AMPs, whereas Braidwood has 44 applicable. The total count of AMPs that have exceptions for Byron is 9; the total count for Braidwood is 10.

As stated in SER Section 3.0.3.2.11, the staff considered 2 instances of the applicant's Fire Water System program to be exceptions to the recommendations of LR-ISG-2012-02. The staff determined that the exceptions were acceptable and that the program, with enhancements and exceptions, is adequate to manage the effects of aging for the fire water system.

The Flux Thimble Tube Inspection program is an existing program and has an exception and three enhancements applicable only to Braidwood; therefore for Braidwood it is "consistent with enhancements and exceptions," and for Byron it is considered "consistent." This is reflected in the count of "consistent" programs for Byron and the "consistent with enhancements and exceptions" count for Braidwood.

If you have any questions, please contact John Daily, the license renewal Safety Project Manager for this application, at 301-415-3873 or by email at John.Daily@NRC.Gov.
