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) in response to NRC Regulatory Issue Summary 2005-05 (Reference 2). The proposed change modifies TS 3.9.12, Fuel Storage, to define spent fuel loading restrictions for the Holtec International HI-STORM 100 Cask System for 32 assembly Multi-Purpose Canisters (MPC-32).

On July 26, 2005, members of your staff requested that Entergy provide a copy of the criticality analysis that was performed in support of the application. Portions of the calculation are considered proprietary in accordance with 10 CFR 2.390, Public Inspections, Exemptions, Requests for Withholding. Attachment 1 is the proprietary version of the criticality analysis which is requested to be withheld from public disclosure. Attachment 2 contains a redacted non-proprietary version of this criticality analysis. Attachment 3 contains the Holtec affidavit substantiating the basis for withholding the document from public disclosure.

The original no significant hazards consideration included in Reference 1 is unaffected by the information contained in this letter. There are also no new commitments contained in this letter.
