SUBJECT:

ARKANSAS NUCLEAR ONE, UNIT 1 - REQUEST FOR ADDITIONAL INFORMATION - RELOCATION OF INVERTER Y-28 AND PANEL C-540 REQUIREMENTS FROM THE TECHNICAL SPECIFICATIONS TO THE TECHNICAL REQUIREMENTS MANUAL (TAC NO. MD2982)

Dear Mr. Forbes:

By letter dated August 31, 2006, Entergy Operations, Inc., requested an amendment to the Arkansas Nuclear One, Unit 1, Technical Specifications (TS). The proposed change would relocate TS 3.8.7 requirements associated with 120 volt inverter Y-28 and TS 3.8.9 requirements associated with 120 volts alternating current electrical power distribution subsystem panel C-540 to the technical requirement manual.

The staff of the Nuclear Regulatory Commission has reviewed the proposed request and finds that additional information is needed to complete its evaluation. A request for additional information is enclosed.

In order to complete our timely review of your amendment request, we request your response within 30 days from the date of this letter. If you have any questions, please contact me at 301-415-1447.

Sincerely,

/RA/

ENCLOSURE REQUEST FOR ADDITIONAL INFORMATION ENTERGY OPERATIONS, INC.

ARKANSAS NUCLEAR ONE, UNIT 1 TAC NO. MD2982 DOCKET NO. 50-313 1.

Define the term vital equipment. Once the requirements for the 120 volt inverter, Y-28, are moved to the technical requirements manual, will Y-28 still be considered a vital inverter?

2.

On Page 2 of Section 3.0 of the attachment to the amendment request dated August 31, 2006, Entergy states that panel C-540 provides power to some alternate shutdown instrumentation. Please provide detailed information on the affected alternate shutdown instrumentation. In addition, provide justification that the operators response when establishing fire-related compensatory measures upon loss of C-540 has no adverse effects.
