THIMBLE TUBE THINNING IN WESTINGHOUSE 'REACTORS Gentlemen:
Carolina Power and Light Company (CP&L) hereby submits the information for the Shearon Harris Nuclear Power Plant (SHNPP) required by NRC Bulletin No. 88-09, "Thimble Tube Thinning in Westinghouse Reactors." This bulletin requested addresses to establish and implement an inspection program to periodically confirm thimble tube integrity as well as perform any corrective measures necessary to maintain thimble tube integrity within the program acceptance criteria.
A program consistent with the recommendations identified in the bulletin has been developed. This program will be formally implemented by Engineering Periodic Test procedure EPT-114, "Eddy Current Testing Requirements for the Incore Instrumentation Thimbles."
Thimble tube inspection using the criteria formulated during program development was conducted during the August 1988 Refueling Outage.
Corrective and preventive measures were implemented to maintain thimble tube integrity within the developed acceptance criteria.
Five thimbles were repositioned based on detection of wall degradation (( 30Z) near the lower core support plate. One 8811160287 88iii0 PDR ADttCK 05000400 9 PDC MEM/HO-8802340/1/OS1
