Dear Sir or Madam:

Entergy Operations, Inc., (Entergy) submitted the Arkansas Nuclear One, Unit 1 (ANO-1)

Inservice Inspection Summary Report for the twenty-fourth refueling outage (1R24) via the reference. This report was provided in accordance with Article IWA-6000 of Section XI of the 2001 Edition with the 2003 Addenda of the American Society of Mechanical Engineers Code.

The summary report contained an Owners Activity Report Form OAR-1 in place of the code-required forms.

This report was prepared at the completion of the refueling outage and submitted within 90 calendar days of the completion of the outage. This outage was completed on August 7, 2013.

During the Authorized Nuclear Inservice Inspectors review of the submitted report it was determined that some of the information that was provided was from previous OARs and not applicable to this report. Specifically Code Cases N-661 and N-513-1 were not utilized during the reporting period. In addition, the information in Table 1 of the report related to the HBD 18 repair was performed and reported correctly in the previous cycles report.

Based on the above, attached is the completed revised Form OAR-1 for ANO-1 for your information. Included with the form are tables listing the Items with Flaws or Relevant Conditions that Required Evaluation for Continued Service and Abstract of

1CAN111301 Page 2 of 2 Repair/Replacement Activities Required for Continued Service in accordance with Code Case N-532-4. The results that are contained in the revised form are for 1R24.

By means of this submittal, the reporting requirements of IWA-6000 are fulfilled for 1R24.

If you have any questions or require additional information, please contact me.
