ENCLOSURE TURBINE MAINTENANCE COMMITMENT FOR THE RIVER BEND TURBINE MISSILE ISSUE We have reviewed the River Bend facility with regard to the turbine missile issue and conclude that the probability of unacceptable damage to safety-related systems and components due to turbine missiles is acceptably low (i.e., less than 10" per year) provided that the turbine missile

-5 generation probability is maintained to be 10 per reactor year or less for the life of the plant by an acceptable maintenance program.

In reaching this conclusion, the staff has factored into consideration the unfavorable nrientation of the turbine generator.

The staff considers the turbine missile issue as a confirmatory item if the applicant agrees to:

a) submit for NRC approval, within three years of obtaining an operating

~

license, a tu'rbine system maintenance program based on the manu-facturer's calculations of missile generation probabilities, or b) volumetrically inspect all low pressure turbine rotors at the second refueling outage and every other (alternate) refueling outage thereafter until a maintenance program is approved by the staff, and c) conduct turbine steam valve maintenance, (following initiation of power output) in accordance with present NnC recommendations as stated in SRP Section 10.2 of NUREG-0800.
