• This column is interpreted to represent the cumulative number of exams performed to date in this period.

This column is interpreted to represent the cumulative percentage of scheduled exams for the interval which have been completed to date in this period.

NOTES:

1. Examinations for pumps and valves are limited to~components selected for examination under Examination Categories B-L-1, B-L-2, and B-M-2.

2. Examination Categories B-N-l, B-P, and B-Q do not have to follow the required percentages of Table IWB-2412-1.

3. Examinations for Examination Categories B-A, B-L-1, B-N-2, B-N-3, and B-O may be deferred to the end of the inspection interval.

4. Examinations for Examination Categories B-G-1, B-G-2, B-L-2, and B-M-2 may be deferred until disassembly of a component for maintenance, repair/replacement, or volumetric examination, Three B-M-2 examinations were not conducted during the interval since the valves in the groupings were not dissassembled for maintenance. One B-L-2 examinations was not conducted during the interval since any of the four RCPumps were not dissassembled for maintenance

5. Visual Examinations (VT-2) for system leakage tests are performed each fuel cycle, period, and interval, according to the requirements of IWA-2212 and IWA-5240. All required VT-2 examinations have been completed for this fuel cycle, except for portions of the CVCS system in packages 1-CS-2-3-1 a (work order 3533774), 1-CS-2-3-1 b (work order 3953452), 1-CS-2-3-2( work order 3856087), 1-CS-2-3-4a (work order 3855975), 1-CS-2-3-4b (work order 3855943), 1-CS-2-3-4c (work order 3855957), 1-CS-2-3-4d (work order 3855916); portions of the SI system in packages 1-SI-2-3-2b (work order 3945812), 1-SI-2-3-2d (work order 3945818), 1-SI 3-2e (work order 3945824), 1-SI-2-3-2h (work order 3945830); portions of the SF system in package 1-SF-2-3-1 b ( work order 3945841);

and portions of the SW system in packages 1-SW-2-1 -1 a ( work order 3535538), 1-SW-1 3-1 b ( work order 3935340), 1-SW-2:3-2a (work order 3535560), 1-SW-2-3-2b (work order 39353450)

6. Examination Category R-A includes previous Examination Categories B-F, B-J, C-F-i, and C-F-2.

7.. Examination Category B-K for the second period includes one Category B-K-1 examination that was completed in 1RF1 0.

8. Examination Category B-Q, Steam Generator Tubing,is reported per the requirements of the Plant Technical Specifications.

9. Replacement of the four Steam Generators with four new Steam Generators in 1RF1 2 removed six Steam Generator Category B-B welds, which were scheduled for examination in the second period. Refer to EVAL-2005-001089-02-00. Two Pressurizer Category B-B welds were rescheduled and examined in 1RF1 2 and the second period.

10. Replacement of four Steam Generators with four new Steam Generators in 1RF1 2 removed six Steam Generator Category B-D welds, which were scheduled for examination in the second period. Refer to EVAL-2005-001089-02-00. Two Pressurizer B-D welds were rescheduled and examined in 1RF1 2 and the second period. Two of the eight B-D welds for the four new Steam Generators were examined during the third period (1 RF14).

11. Only one of six B-A welds examined for Reactor Vessel Head because Head was replaced in 1RF1 2. New Reactor Vessel-Head is a forging, with no B-A welds.

12. Eighteen B-A and fourteen B-D welds for the Reactor Vessel were not examined this interval because Relief Request B-9, which was approved by NRC, allowed the examination frequency for these welds to increase from 10 to 20 years.

13. One B-0 examination was completed in 1RF09(lst period) and was not accounted for in later OAR-1 Reports. Reactor Vessel Head was replaced with a new head in 1RF12 (2nd period). Twenty five percent (1 out of 4) of the penetrations required examinations per Code and was conducted in 1RF14.

14. One C-A examination was completed in 1RF13 and was not reflected in the IRF13 OAR-1 report.

15. Examination numbers reflect changes that occurred during the interval based on the periodic evaluations/updates conducted during the first and second periods. RI-ISI is a living program and follows the requirements in a relief request, approved by the NRC in NRR Log 10027, which allows alternative RI-ISI examinations to be conducted for selected ASME Code Class 1 and 2 welds and the guidance, provided in document NEI-04-05..
