Discuss the basis for establishing the diesel generator operability date of October 24, 1986.
2.
When was start-up testing completed for each diesel?
a)
What were the totals for hours of operating time and effective full-load hours during start-up testing for each?
b)
After start-up testing was completed, were the diesels used before the operability date of October 24, 1986?
Discuss the purpose, the total operating time, and the total full-effective hours associated with each engine.
c)
Provide the total number of hours that each diesel has accumulated since low power operation began in October 1986.
(Effective full-load and total operating time).
3.
Provide the basis for your determination that the components not inspected as required by the Transamerica Delaval, Inc. (TDI), Owners Group, during the five-year inspection, were "visually inspected with satisfactory results,"
as noted in your letter dated September 25, 1991.
4.
What is the justification for continued operation when the licensing basis was not met due to omission of required recorded measurements of several components for the "A" diesel

Was a review completed in accordance with 10 CFR 50.59?
5.
Provide the basis for completing both "A" and "B" diesel generator inspections at the end-of-cycle (EOC) after five years versus
- doing, as recommended by the TDI Owners Group, one engine inspection at the closest EOC prior to five years and the other at the EOC after five years.
6.
Discuss what actions have been completed, or are scheduled to be completed, to ensure all recommended inspection points and measurements are reviewed and incorporated into Carolina Power E Light Company's Maintenance Inspection and Procedure Records.
