Ms. E. G. Adensam, Chief Licensing Branch No. 4 Re: Catawba Nuclear Station, Unit 2 Docket No. 50-414
Dear Mr. Denton:
By letter dated April 5, 1984, Duke Power Company subuitted a report entitled " Catawba Nuclear Station Extended Operation Tests and Inspections of Diesel Generators". This report, along with subsequent submittals, described the extensive test and inspection program that was carried out on the Catawba 1A and 1B diesels.
As a result of the completion of this program for the Catawba Unit I diesels, a test and inspection plan for the Catawba Unit 2 diesels has been developed. The preoperational testing on the 2A and 2B diesels will be conducted in accordance with FSAR Section 8.3.1.1.3.10.
This section will be updated to reflect the current Technical Specification references as noted in the attached marked-up FSAR page.
The quality revalidation inspection plan for both the Unit 2 engines is similar to that used for the inspection of the Catawba IB diesel engine.
The quality revalidation recommendations included in the TDI Diesel Generator Owners Group Design Review / Quality Revalidation Final Report have also been included in the Unit 2 inspection plan. As with the Unit I diesels, the inspection plan is submitted in tabular form showing the various inspections for each part and the size of the sample to be inspected. This inspection plan matrix is included as an attachment to this letter. Teardown and inspection of the 2A diesel started March 25, 1985, and is scheduled to be finished by July 1,1985. The 2B diesel inspection will start after the 2A diesel has been returned to service.
The majority of design review modifications recommended by the TDI Diesel Generator Owners Group Design Review / Quality Revalidation Final Report will be implemented on Unit 2.
These modifications also will be done on Unit 1.
Several other modifications are under engineering review

for both units. Action on these will not be implemented until review is completed. The review will be completed well in advance of the first refueling outage for both units so that sufficient time is allowed for appropriate action.
l Very truly yours.
