Subject:
Docket 50-482: Inservice Inspection Program Second Interval, Second Period Owner's Activity Reports Gentlemen:
In References I and 2, Wolf Creek Nuclear Operating Corporation (WCNOC) requested use of ASME Code Case N-532 aAlternative 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 USNRC 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-1 prepared during an inspection period shall be submitted following the end of the inspection period. The enclosures provide the Owner's Activity Reports for the period October 4, 1999 through December 31, 2002. This timeframe constitutes the second period of the second interval of the WCNOC Inservice Inspection Program. Within this period, Refueling Outages 11 and 12 occurred. The enclosed Forms OAR-1 (Reports WCRE-10, 12-P2-RF-11 and WCRE-10, 12-P2-RF-12) correspond to these outages.

Note 1: 216 of the 219 examinations for category B-G-I are comprised of the reactor vessel studs, nuts, washers, and flange ligaments. The other three examinations are performed on the studs, nuts and washers, and flange surfaces of a reactor coolant pump. In RFO-9, RCP-D was disassembled, and the flange face surfahces were examined.
Note 2: For pumps and valves, examinations are limited to components selected for examination under Examination Categories B-L-2 and B-M-2.
Note 3: Examination is required only when a pump is disassembled for maintenance, repair or examination.
Examination is required only once during the inspection interval, thus completed percentages indicated may not be consistent with Table IWB-2412-1 schedule. In RFO-9, RCP-D was disassembled, and the pump casing surfaces were examined.
Note 4: Examination is required only when a valve is disassembled for maintenance, repair or examination.
Examination is required only once during the inspection interval, thus completed percentages indicated may not be consistent with Table IWB-2412-1 schedule.
Note 5: Visual Examinations (VT-2) are performed as required for a fuel cycle, 40-month, and 10-year system hydrostatic testing basis. All required exams have been performed for this fuel cycle.
Note 6: For simplicity, numbers and percentages are based only on circumferential welds selected for examination. When a circumferential weld is intersected by a longitudinal weld, that longitudinal weld is selected by default in the WCNOC Program. This approach results in greater than the 7.5% sample of longitudinal seam welds being inspected, exceeding the ASME Code requirements.
Note 7: Includes augmented exams required by NUREG 0800 and RCP Flywheel Exams.
Note 8: Numbers do not include Visual Examinations (VT-2) as required for 40-month and 10-year system hydrostatic testing basis. AU required exams have been performed for this fuel cycle.
Note 9: Relief Request 12R-23 is being submitted to approve an incomplete examination for Category C-B. Per WCNOC program protocol, this incomplete exam has not been counted in Table 1. Thus, the total exams credited percentage is shown as being below the 16% minimum. Following NRC approval of Relief Request 12R-23, Table 1 will be updated to reflect that exam as complete, and the Category percentage will be 25%.
Note 10: A Relief Request is being prepared to approve one incomplete examination for Category C-F-2 and 13 incomplete examinations in the Augmented Category. Per WCNOC program protocol, these incomplete exams have not been counted in Table 1. Following NRC approval of the Relief Request. Table I will be updated to reflect those exam as complete, and the Category percentage will be adjusted accordingly.
Note 1: During the last revision of WCRE-1 0, the pressurizer integral attachments were correctly reclassified as category B-H instead of B-K.

In accordance with NRC GL 91-018 for class 3 piping (moderate energy), the evaluation and acceptance criteria from GL 90-S05 and Code Case N-513 was used to determine that the system was suitable for continued service. On 3/312000, it was determined that the degradation had progressed to the point that the piping no longer had structural integrity as defined by Code Case N-513. The degraded
- components were then replaced per Repair/Replacement Plan 2000-004.

Note 8: Eight Category C-B components were originally scheduled for examination in Interval 2, two in Period 1, three in Period 2, and three in Period 3. Two Category C-B exams were performed for ISI credit in Period I (Relief Request 12R-23 was submitted to the NRC for approval of an incomplete exam in Period I and was approved by the NRC in a letter dated April 23, 2003). Three Category C-B examinations were completed for ISI credit in RF12, which brought the number of exams completed for the Interval to five. One of the components originally scheduled for examination in Period 3 was discovered to be a solid forging with holes drilled, thus no inner radius exists for this component. Removal of one of the exams scheduled for Period 3 has resulted in 71% completion of the exams required for the Interval.
Note 9: Wolf Creek has implemented changes that has removed many snubbers and associated supports from plant configuration. Thus the number in the "Total Examinations Required For The Intervarl column for category F-A is less than that shown in the RF-I I report. The sample percentage requirements of Code Case N491-1 continue to be met.
Note 10: Categories B-F, B-J, C-F-1, and C-F-2 welds are now examined under the RI-ISI program In the safety evaluation of the WCNOC RI-ISI program, the NRC approved WCNOC's proposal that since 33 percent of the ASME Section Xl exams had been performed in Period 1 and the first part of Period 2, then 67 percent of the RI-ISI scope would be examined during the remainder of Period 2 and Period 3, so that 100% of selected exams are completed during the interval.
