SUMMARY

REPORT FOR THE TWENTY-SECOND REFUELING OUTAGE (R22)

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 In-Service Inspection summary report be submitted to regulatory and enforcement authorities having jurisdiction at the plant site.

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 for the twenty-second refueling outage (R22) for Columbia Generating Station (Columbia). The outage was completed on June 28, 2015.

Code Case N-532 allows Energy Northwest to prepare an Owners Activity Report Form OAR-1 in place of the Code required NIS-1 and NIS-2 forms for the summary report.

The latest revision of this code case, N-532-5, is listed in Regulatory Guide 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.

The enclosure to this letter, Inservice Inspection Summary Report for Third Inspection Interval Third Inspection Period Refueling Outage R22, is herewith being submitted, which includes the completed Form OAR-1 for Columbia. 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 contained in this completed form are for activities performed during cycle 22 up to and including refueling outage R22.
