SUBJECT:
BROWNS FERRY UNIT 3 - ACCEPTANCE REVIEW RESULTS FOR THIRD INTERVAL RISK INFORMED INSERVICE INSPECTION RELIEF REQUEST NO. 3-ISI-21 (TAC NO. MC8795)
Dear Mr. Singer:
By letter dated October 19, 2005, the Tennessee Valley Authority (TVA) submitted its third 10-year Inservice Inspection (ISI) program for Unit 3 of the Browns Ferry nuclear power plant.
TVA proposes to implement a Risk-Informed Inservice Inspection (RI-ISI) program in lieu of an American Society of Mechanical Engineers (ASME)Section XI to the Boiler and Pressure Vessel Code (ASME Code or Code) ISI program. The regulatory requirement for acceptability, as provided in Title 10 to the Code of Federal Regulations, Part 50, Section 55a(a)(3)(i), states that the proposed alternative provides an acceptable level of quality and safety. The U.S. Nuclear Regulatory Commission (NRC) staff has determined that the safety analysis submitted with the relief request does not provide sufficient technical information to enable the NRC staff to make an independent assessment regarding the acceptability of the proposal.
TVA states that its proposed process is similar to that previously submitted for the second 10-year interval without identifying the differences between the previously approved and the proposed process and resulting ISI program. For example, the NRC staff notes that the proposed program includes the removal of Class 3 piping welds without addressing how this removal affects the overall program. Therefore, in order to make the submittal complete, TVA needs to submit a sufficiently-detailed description of the proposed changes and how these changes affect the implementation of the RI-ISI program.
This request was discussed with Mr. Tony Langley of your staff on December 1, 2005, and it was agreed that a response would be provided within 60 days of receipt of this letter.
K. Singer Upon receipt of information that adequately addresses these deficiencies, the NRC staff will consider your application complete, such that the detailed technical review can be initiated and a schedule for completing the review can be established.
If you have any questions, please contact me at (301) 415-2315.
Sincerely,
/RA/
