ENCLOSURE 3.5.1.3 Turbine thissiles The staff has reviewed the Shearon Harris facility with regard to the turbine missile issue and concluded that the probability of unacceptable damage to safety-related systems and components due to turbine missiles is acceptably Iow (i.e., less than 10 7 per year) provided tha) the turbine missile 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 orientation of the turbine generator.

The staff considers the turbine missile issue as a confirmatory item if the Shearon Harris project will do the following:

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

license, a turbine system maintenance program based on the manu-facturerr'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 conduct turbine steam valve maintenance (following initiation of power output) in accordance with present NRC recommendations as stated in SRP Section 10.2 of NUREG-0800.
