Subject:

'Docket 50-482: Containment Inservice Inspection Program First

- §- Interval, First Period Owner's Activity Reports Gentlemen:

In References land 2,-Wolf Creek Nuclear Operating Corporation (WCNOC) requested use of American Society of Mechanical Engineers -(ASME)- Code Case -N-532, -"Alternative Requirements to Repair and- Replacement- Documentation Requirements -and Inservice Summary Report Preparation and Submission as Required by IWA-4000 and IWA-6000," in lieu of current ASME Section Xl reporting requirements.

In Reference 3,-the Nuclear Regulatory Commission (NRC) concluded that-the proposed alternative to use Code Case N-532 and the clarifications contained within References 1 and 2 provide an acceptable level of quality and safety, and approved the use of Code Case N-532 for use at Wolf Creek Generating Station. Code Case N-532 requires that an Owner's Activity Report (Form OAR-1) be prepared and certified upon completion-of each refueling outage.

Each Form OAR-I prepared during an inspection period shall be submitted following the end of the inspection period. The enclosure provides the Owner's Activity Reports for the first period of the first interval of the WCNOC Containment -Inservice Inspection Program. Refueling Outage 11 occurred within this period. -The enclosed OAR-1 forms correspond to Refueling Outage 11 and the operational cycle since the completion-of Refueling Outage 10. The initial inspections of the Containment Inservice inspection Program commenced during this time.

Although Refueling Outage 10 occurred during the first period of the program, no containment inspections were scheduled or performed during Refueling Outage 10 and no Form OAR- was completed. A-separate Form OAR-l was prepared for subsections IWE and IWL of -the Containment Inservice Inspection Program.

Note 2: In accordance with IOCFR50.55a, the expedited containment tendon inspections may be satisfied by the existing WCNOC Program for tendon inspections. Accordingly, containment tendon inspections were performed in accordance with the existing WCNOC Program for tendon inspections, as defined and implemented by Technical Specifications sections 3.6.1 and 5.5.6 rather than in accordance with Section XI Subsection IWL. The 10CFR50.55a(b)(2)(viii) limitations and modifications regarding documentation of tendon inspections results do not apply to the expedited containment tendon inspections satisfied by the existing WCNOC Program. However, no conditions were identified applicable to examination category L-B that would have required documentation in this report if the inspections were being performed in accordance with Subsection IWL.
