Dear Sir or Madam:

By letter (Reference 1), Entergy Operations, Inc. (Entergy) proposed a change to the Arkansas Nuclear One, Unit 2 (ANO-2) Technical Specifications (TSs) to allow a one-time extension of the containment spray system allowable outage time. A supplemental letter was also provided (Reference 2). provides a copy of the clean TS page which includes a minor modification. The original proposed change limited the one-time extension to fuel cycles 18 and 19. The modified page reflects a change in the fuel cycles to cycles 19 and 20. This does not result in a technical change to the original submittal or supplemental response. The original no significant hazards consideration included in Reference 1 is not affected by the change on the TS page. There are no new commitments contained in this letter.

If you have any questions or require additional information, please contact Dana Millar at 601-368-5445.
