Issuance of Amendment Nos. 305, 328, and 288 to Revise Technical Specification 5.5.12, Primary Containment Leakage Rate Testing Program (CAC Nos. MG0113, MG0114, and MG0115; EPID L-2017-LLA-0292), dated September 27, 2018 (ML18251A003)

The purpose of this letter is to notify you of a typographical error discovered in the referenced documents during the course of an internal self-assessment. In Reference 1, in response to RAI SCPB RAI-2c, Tennessee Valley Authority (TVA) made the following statement:

3-FCV-77-2B has an Administrative limit of 6 scfh. The RF16 as-found test result was 10.85 scfh. The valve was disassembled, cleaned and inspected. The RF16 as-left result was 1.91 scfh [emphasis added].

Based on that information, Reference 2 reiterated that the BNF Unit 3 Refueling Outage 16 post-maintenance test as-left result for 3-FCV-77-2B was 1.91 standard cubic feet per hour (scfh). In fact, review of the as-left testing records showed a lesser leakage rate of 1.61 scfh.

U.S. Nuclear Regulatory Commission CNL-18-129 Page 2 November 29, 2018 This issue has been entered into the TVA Corrective Action Program, and the Nuclear Regulatory Commission (NRC) Project Manager for the Browns Ferry Units was notified. TVA's assessment is that the error had no impact on plant safety or any evaluations or conclusions contained in the Safety Evaluation.
