SUBJECT:
BROWNS FERRY NUCLEAR PLANT, UNIT 1 - REQUEST FOR ADDITIONAL INFORMATION REGARDING REVISION TO EXCESS FLOW CHECK VALVE SURVEILLANCE TESTING FREQUENCY (TS-438) (TAC NO. MC4659)
Dear Mr. Singer:
By letter dated October 12, 2004, Tennessee Valley Authority (TVA) submitted a request for a Technical Specification change (TS-438) to revise the frequency of Surveillance Requirement 3.6.1.3.8 by testing a representative sample of excess flow check valves (EFCVs) every 24 months, so each EFCV is tested once every 120 months.
Based on our review of your submittal, the NRC staff finds that a response to the enclosed request for additional information is needed before we can complete the review.
This request was discussed with Mr. Tim Abney of your staff on March 31 and April 6, 2005, and it was agreed that a response would be provided within 30 days of the issuance of this letter.
If you have any questions, please contact me at (301) 415-4041.
Sincerely,
/RA/
Margaret H. Chernoff, Project Manager, Section 2 Project Directorate II Division of Licensing Project Management Office of Nuclear Reactor Regulation Docket No. 50-259
Enclosure:
Request for Additional Information cc w/encl: See next page
Enclosure Request for Additional Information TS-438, Revision to Excess Flow Check Valve (EFCV) Surveillance Testing Frequency 1.0 Page E1-7 under Section B, "EFCV Failure rate" states that TVA will address crud build up and valve sticking by flushing lines and inspecting 100 percent of the EFCVs. The application does not address the time period between performance of the testing and startup of the plant. How will EFCV operability be maintained/assured during the time period between completion of the testing and startup of the plant?
2.0 For EFCV refueling testing it is not clear what action the licensee will take if an EFCV failure is identified within the "representative sample" or if a repeat EFCV failure is noted. For example, will another "representative sample" be tested?
3.0 The Radiological Dose Assessment of your submittal states that the leak flow rates and fluid pressure are taken from General Electric NEDO-21143-1, Radiological Accident Evaluation - The CONAC03 Code, dated December 1981. Please submit a copy of this report, or provide a reference to a prior submittal of this report.
