13. Abstract of Examinations and Tests This submittal is for the ISI examinations performed during the Oyster Creek Generating Station 1R20 refuel outage. This is Oyster Creek's first submittal for the fourth inspection interval. The exams were completed in accordance with the 1995 Edition of the ASME Code with 1996 Addenda.

One hundred sixty three (163) exams were completed on Class 1 and 2 systems for ASME Section Xl requirements, ten (10) exams were completed for augmented requirements, and seventeen (17) exams were completed for Generic Letter 88-01 requirements. In addition, visual and UT examinations were completed on the drywell and torus in accordance with ASME Section IWE (Containment Program). In summary, all examinations were completed successfully.

Refueling Outage Inspection Results for the CRD Housing Inspections During the 1R20 outage, AmerGen performed inspections of the CRD housings to identify any leakage from the RPV bottom head penetrations. No leakage was observed during the drywell 1000 lb. VT-2 inspection performed during the initial shutdown. During the outage, undervessel inspections were performed on all CRD housings during set-up activities for CRD exchange (RPV vented) and no stub tube leakage was identified from the RPV bottom head.

Based on a target of opportunity for access to one of the roll repaired CRD housings, the CRD housing bore at core location 46-39 was UT inspected. Both the roll repair area and the J weld area above it were UT inspected with no indications. Undervessel VT-2 inspections were also performed during the RPV pressure test at approximately 1000 Ibs and no stub tube leakage was found (WO R2032133). A final undervessel inspection was performed during the plant startup drywell 10001b. Inspection and no stub tube leakage was found.

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 Xl, 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-416-1 were utilized for welded repairs or installation of replacement items by welding.

There were challenges identified during this inspection on the Core Spray system piping supports and the NU-2-2 weld on the shutdown cooling system. In the area of supports, scope expansion (11 extra support exams) was required due to unacceptable as-found conditions on rod hangers.

The NU-2-2 dissimilar metal weld in the drywell was initially identified by manual UT with a flaw.

However, upon re-examination of this weld with improved and automated UT techniques (SMART UT) the flaw was no longer identified and a weld overlay repair was not required.

15. Abstract of Corrective Measures See Table 2 for ISI and in-vessel visual inspection (IWI) 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 1R20 outage. 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 by the end of the interval for approval of these limited coverage examinations. See Table 5 for system pressure test results.

13. Abstract of Examinations and Tests Oyster Creek is at the end of the second 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 and exterior of the drywell and torus suppression chamber. The augmented examination of the drywell liner 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 Two (2) examinations resulted in recordable conditions and CAPs were initiated. A weld rod was found stuck to the underside of the Drywell head and reported on CAP 02004-3437. A loose locknut was identified on a spare drywell penetration and reported on CAP 02004-3586.

15. Abstract of Corrective Measures The weld rod that was found stuck (welded) to the underside of the drywell head was visually examined and no indications were found in the area of the arc strike. An engineering evaluation was performed (C2007833-04) that dispositioned the weld rod as use-as-is. This weld rod appeared to be from plant construction. The loose locknut did not affect the seal of the penetration and was reported to maintenance to be tightened.
