Dear Mr. O'Reilly:
SEQUOYAH NUCLEAR PLANT UNITS 1 AND 2 - SPENT FUEL POOL GATES - NCR SQN NEB 8012 - SL?PLEMENTAL INFORMATION TO THE FOURTH REVISED FINAL REPORT The subject deficiency was initially reported to NRC-0IE Inspector J. D. Wilcox on May 1, 1980 in accordance with 10 CFR 50.55(e). Reports were submitted on May 29, June 18, July 2, September 8, and October 15, 1980 and May 18, 1982. Enclosed is supplemental information pertaining to this deficiency.
If you have any questions, please get in touch with R. H. Shell at FTS 858-2688.
Very truly yours, TENNESSEE VALLEY AUTHORITY

- s ENCLOSURE SEQUOYAH NUCLEAR PLANT SPENT FUEL POOL GATES NCR SQN NEB 8012 10 CFR 50.55(e)
SUPPLEMENTAL INFORMATION The Sequoyah gate designs for the transfer canal and the cask loading area were reanalyzed under new design criteria. The gates were found to be inadequate. At the present time, there is no spent fuel stored in the spent fuel pit. Therefore, if a seismic event occurred, failure of these gates would not create a safety problem. The gates will be modified before placing any spent fuel in the spent fuel pit.
The transfer canal and the cask loading area gates at Sequoyah were designed with paired restraints attached to the pool wall at the top and at the bottom of the gates. Intercediate restraints will be added for both gates at Sequoyah to meet seismic requirements.
The previous SQN reports addressed the gates for WBN and BLN. Those gates were also reanalyzed under the new design criteria and were found to be inadequate. Separate 10CFR50.55(e) reports are being prepared on those plants.
