FORM NIS-1 OWNER'S REPORT FOR INSERVICE INSPECTIONS Form NIS-1 for ISI Program 13. Abstract of Examinations and Tests This submittal is for the ISI examinations performed during the Oyster Creek Generating Station 1 R21 refuel outage. This is Oyster Creek's second submittal for the fourth inspection interval.

The exams were completed in accordance with the 1995 Edition of the ASME Code with 1996 Addenda. A total of one hundred twenty six (126) exams were completed on Class 1 and 2 systems for ASME Section XI requirements.

Refer to Table 5 for system pressure test results.14. Abstract of Results of Examinations and Tests Welds categorized as B-J, C-F-1 and C-F-2 were examined to the requirements of PDI, in compliance with the amended requirements of 10CFR50.55a for implementation of Appendix VIII of the ASME Section XI, 1995 Edition with 1996 Addenda. The reactor pressure test of the reactor coolant pressure boundary was completed at the end of the outage. Leakage at bolted flange connections was observed on some control rod drives (CRDs) and this was evaluated in accordance with Code Case N-566-1. The alternative pressure test requirements of Code Case N-416-3 were utilized for welded repairs or installation of replacement items by welding.There were challenges identified during this inspection on the Main Steam, Isolation Condenser and Reactor Building Closed Cooling Water system piping supports in the Drywell. Scope expansion was required due to unacceptable as-found conditions on pipe supports.15. Abstract of Corrective Measures See Table 2 for ISI and in-vessel visual inspection (IVVI) corrective measures.

For ISI components not associated with IWI no indications were detected by the examinations, and there was no through-wall leakage identified at the pressure boundary.

Table 3 provides the statistics for ISI examinations completed during the 1 R21 outage and includes a correction from the last submittal for Category B-K. Refer to Table 4 for the ISI examinations that were completed that did not meet ASME code coverage requirements.

The limitations were due to nozzle geometry, restricted access, and one-sided examinations due to attached nozzle or valve. A relief request will be submitted near the end of the interval for approval of these limited coverage examinations.

Abstract of Examinations and Tests Visual and UT examinations were completed on the drywell and torus in accordance with ASME Section IWE (Containment Program).

Oyster Creek is at the start of the third period of the first inspection internal for containment inspections.

These examinations were performed to fulfill the requirements of ASME Section Xl, 1992 Edition with 1992 Addenda. Examinations were performed on all accessible areas of the interior of the drywell and torus suppression chamber, including underwater inspections of the torus.An augmented examination of the drywell shell and exterior sand bed area was also performed.

A list identifying the components inspected has been attached as Table 1.14. Abstract of Results of Examinations and Tests The results from the inspection of the drywell sand bed region confirmed that corrosion on the outside of the drywell shell has been arrested.

UT measurements of the drywell at 19 monitoring locations for the sand bed region were satisfactory.

The visual inspection of 100% of the epoxy coating in the sand bed region showed it to be in good condition.

On the inside of the drywell, water was found in between the drywell concrete floor and the interior drywell shell. This water originated from typical drywell equipment leakage inside the drywell.Inspection results for the inside of the Torus identified that the underwater coating is continuing to protect the shell from further degradation.

No significant issues were identified on the Torus as result of the visual inspections completed above and below the water.15. Abstract of Corrective Measures Due to identification of the water between the drywell concrete floor and the interior drywell shell, a new moisture barrier (caulk) was applied between the drywell interior floor and the drywell shell. A PSI inspection (VT-3) was performed of this new moisture barrier and it will be added to the Oyster Creek IWE program scope for future inspections.
