SUBJECT:

Inservice Inspection Summary Report for the Twenty-Fifth Refueling Outage (2R25)

Arkansas Nuclear One, Unit 2 Docket No. 50-368 License No. NPF-6

Dear Sir or Madam:

Article IWA-6000 of Section XI of the 2001 Edition with the 2003 Addenda of the American Society of Mechanical Engineers (ASME) Code requires an inservice inspection summary report to be submitted to the regulatory and enforcement authorities having jurisdiction at the plant site. The summary report is to contain the completed Form NIS-1, Owners Report for Inservice Inspection, and Form NIS-2, Owners Report for Repair or Replacement Activity.

This 2001 Edition with the 2003 Addenda of the ASME Code is the code of record for the fourth 10-year interval at Arkansas Nuclear One, Unit-2 (ANO-2).

ASME Code Case N-532 allows Entergy Operations, Inc., to prepare an Owners Activity Report form OAR-1 in place of the code-required NIS-1 and NIS-2 forms. The latest revision of this code case used in this report, N-532-5, is listed in Regulatory Guide (RG) 1.147, Inservice Inspection Code Case Acceptability, ASME Section XI, Division 1, Revision 17, Table 1, Acceptable Section XI Code Cases. Therefore, prior NRC approval to implement this code case is not required.

This report is to be prepared at the completion of a refueling outage and submitted within 90 calendar days of the completion of the refueling outage. In this case the report is associated with the twenty-fifth refueling outage for ANO-2 (2R25). This outage was completed on July 8, 2017.

Attached is the completed Form OAR-1 for 2R25 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 Repair / Replacement Activities Required for Continued Service in accordance with Code Case N-532-5. The results that are provided in this submittal are for 2R25.

2CAN101701 Page 2 of 2 By means of this submittal, the reporting requirements of the ASME Code, Section XI, Article IWA-6000 are fulfilled for 2R25.

This letter contains no new commitments.
