Dear Mr. Cahill:

The NRC staff will shortly make its findings concerning the qualified load

< level of the TDI Ercrgency Diesel Generator (EDG) at River Bend. Extended l periods of operation of en engine above the qualified load level could result in danage, rendering the engine ir.cperable. Therefore, we are requesting that you develop engine operating procedures which provide proper guidence ario in-struction to operators against overloading the engines above the qualified loao level. These procedures should address, but not necessarily be limited to, the following:

1. No single operator error should cause the loading of more than one TDI

- engine in excess of its qualified load rating.

2. Procedures and training in place at River Bend should not call for an operator action that would cause the EDG load to excced the qualified load.

i

3. The training prograin should adequately address the technical concerns associated with the qualified load limit on the EDG's.

4. If a situation were to occur that would, for some unspecified failure, cause the EDG to exceed the qualified load, the procedures and training should provide the necessary guidance to reduce the load below the quel-1 ified load within one hour, i 5. Distinctive and unique instrunentation and alarms exist to worn operatcrs when the EDG's are loaded above the qualified load.
