SUMMARY

- UNIT NO. 1 JANAURY 1988 The Unit entered Mode 3 on January 6, 1988. During the 102%

hydrostatic test of the Reactor Coolant System (RCS) , leaks were discovered on three (3) spare control rod drive mechanism (CRDM) penetrations at their lower canopy seal welds. The Unit was cooled down to Mode 5 on January 9, 1988, to facilitate repairs. During a detailed inspection of all CRDM columns while in Mode 5, evidence of leakage was found on three additional columns at the same area. Dye penetrant tests confirmed the existence of possible "pinhole" leaks on two (2) of the three (3} columns. Since none of the leaking columns were removed, the actual cause of the leakage was undetermined.

However, inspection and analysis of the five (5) thermocouple columns yielded a possible cause. The thermocouple columns, which are similar in design to the spare CRDM columns, were removed in conjunction with the installation of the Bottom Mounted Instrument System. The canopy seal areas of all five thermocouple columns exhibited evidence of thermal crevices postulated to be from incomplete fusion of the consumable insert used during the welding process of the canopy seals during the original fabrication. Our analysis, and that of our consultant, suspect some type of pitting originating in the crevice area might be the cause of the canopy seal leaks. None of the five (5) thermocouple columns had any evidence of crevice propagation pitting or leakage. Since there are a total of thirteen spare CRDM columns, it was decided to repair all of them to preclude further problems due to leakage. A weld buildup technique was used on twelve (12) columns and a split canopy seal ring was used on the thirteenth.

The NRC, both at the Region I and NRR levels, was given a presentation and kept informed of our findings and repairs.

Other work performed during the period included: detensioning, removal, and retensioning of nine (9) Reactor Vessel Head studs to remove any boric acid accumulation; cleaning of the vessel head; repairs to the Reactor Cavity seal area; replacement of 12MS14 Main Steam Safety Valve, and replacement of PR3 Pressurizer Safety Valve.

In addition, a leak detection system utilizing an air particulate monitor has been designed and is being installed to detect RCS leakage from penetrations in the Reactor Vessel Head.

The Service Water Bay 1 flood in December 1987, was caused by partial failure of the 13SW20 butterfly valve seat. The valve has been replaced with a new type, hydrostatically tested, and returned to service. All recovery activities associated with other equipment in the Bay have been completed.
