ENCLOSURE FERMI 2 LICENSE RENEWAL APPLICATION REQUEST FOR ADDITIONAL INFORMATION SET 34 (TAC NO. MF4222)

RAI B.1.10-3

Background===

By letter dated February 5, 2015, the applicant provided its response to request for additional information (RAI) 4.1-3. In this letter, the applicant stated that it implements inspections of the top guide assembly and its components in accordance with Technical Report Boiling Water Reactor Vessel and Internals Project (BWRVIP)-183.

Issue:

As of April 22, 2015, the staff has yet to issue formal endorsement of the BWRVIP-183 report.

Although the staff did issue its draft final safety evaluation report (draft FSER) for the BWRVIP-183 report to the Electric Power Research Institute (EPRI) BWRVIP main committee on December 13, 2011-to provide an opportunity to identify any proprietary information and clarify any factual inaccuracies-the staff has yet to receive any feedback from the EPRI BWRVIP main committee on the draft FSER. However, in the draft FSER, the staff imposed three (3) conditions for those BWR license renewal applicants that will be implementing the BWRVIP-183 report during the period of extended operation.

The staff needs clarification on how the applicant plans to address the objectives (e.g.,

inspection, flaw evaluation, repair criteria, etc.) of the BWR Vessel Internals Program for specific inspection and evaluation (I&E) activities of the top guide assembly and its components.

Request: (1) Clarify and justify which BWR Vessel Internals Program objectives (e.g., inspection, flaw evaluation, repair criteria, etc.) the applicant will accomplish using the BWRVIP-183 report when applying the report to specific I&E activities of the top guide assembly and its components.

(2) If the report will be used for flaw evaluations of the top guide assembly and its components, clarify how the flaw evaluation methodology will account for the following factors that may impact the flaw evaluation basis:

a. stress loads for potential flaws detected near component discontinuities

b. conservative flaw growth assumptions in the methodology

c. potential for and impact of severed beam locations if flaw growth assumptions in the flaw evaluation methodology are determined to be non-conservative for the top guide beam locations (3) Update the license renewal application (LRA) and any additional enhancements to Aging Management Program (AMP) B.1.10, as appropriate.
