SUBJECT:

License Amendment Request To Revise the Spent Fuel Pool Loading Pattern Arkansas Nuclear One, Unit 2 Docket No. 50-368 License No. NPF-6

Dear Sir or Madam:

Pursuant to 10 CFR 50.90, Entergy Operations, Inc. (Entergy) hereby requests an amendment for Arkansas Nuclear One, Unit 2 (ANO-2). The proposed amendment will: 1) eliminate credit for the Boraflex neutron absorbing material used for reactivity control in Region 1 of the Spent Fuel Pool (SFP); 2) credit a combination of soluble boron and several defined fuel loading patterns within the storage racks to maintain SFP reactivity within the effective neutron multiplication factor (keff) limits of 10 CFR 50.68; 3) increase the minimum boron concentration in the SFP to 2000 parts per million; and 4) reduce the fresh fuel assembly initial enrichment to less than or equal to 4.55+0.05 weight percent (wt%) uranium-235 (U-235).

The proposed change has been evaluated in accordance with 10 CFR 50.91(a)(1) using criteria in 10 CFR 50.92(c) and it has been determined that this change involves no significant hazards considerations. The bases for these determinations are included in the attached submittal.

The proposed change includes a new commitment which is summarized in Attachment 4.

Entergy requests approval of the proposed amendment by September 3, 2003 in order to support a full core offload during the ANO-2 fall 2003 refueling outage. Once approved, the amendment shall be implemented within 30 days. Although this request is neither exigent nor emergency, your prompt review is requested.

I declare under penalty of perjury that the foregoing is true and correct. Executed on June 30, 2003.
