TENNESSEE VALLEY AUTHORITY CH ATTANOOG A. TENNESSEE 374ol 400 Chestnut Street Tower II November 13, 1979 Mr. D. G. Eisenhut, Acting Director Division of Operating Reactors Office of Nuclear Reactor Regulation U.S. Nuclear Regulatory Comission Washington, DC 20555
Dear Mr. Eisenhut:
Your letter to All Light Water Reactors dated September 27, 1979, requested that TVA comit to implement a containment purge valve qualification program on an expedited basis. In response to a letter from T. A. Ippolito to N. B. Hughes dated November 29, 1978, we initiated a program of analysis to demonstrate the structural adequacy of the purge valves installed at the Browns Ferry Nuclear Plant. Numerous problems and delays were encountered since the valve manufacturer was able to provide very little assistance.
The program and results were presented to the NRC staff in a meeting on June 1, 1979. By letter from J. E. Gilleland to T. A. Ippolito dated June 12, 1979, we submitted the results of our valve analysis and general information including a general description of purge activities; the basis of inerting and for purging; the purge history at the Browns Ferry Nuclear Plant; and the impact of restricted purge operations on availability of power.
The results of those analyses proved that the containment purge valves are adequately qualified to meet the guidelines as presented in your letter dated September 27, 1979.
In view of the June 1, 1979, meeting and the submittals made on the Browns Ferry docket we believe we have been responsive to NRC's concerns regarding containment purging.
Very truly yours, TENNESSEE VALLEY AUTHORITY bM1/$bi w n
