It is the intention of the Philadelphia Electric Company to have these motors replaced or reworked to reestablish the motor warranties. A more detailed report of the damage to the three motors in the Radwaste Building will be submitted after the supplier evaluates the extent of damage and the corrective action required to restore the equipment to meet warranty conditions.

No radioactive materials were inadvertently released or lost as a result of the subject storm and flooding at Peach Bottom Units 2 & 3 and none of the design bases used in our safety evaluation of the facility were exceeded.
