.RAAAA8 16.7-4 LOOSE-PART DETECTION INSTRUMENTATION The OPERABILITY of the loose-part detection instrumentation ensures that sufficient capability is available to detect loose metallic parts in the reactor system and avoid or mitigate damage to reactor system componento. The allowable out-of-service times and Surveillance Requirements are consistent with the recommendations of Regulatory Guide 1.133, " Loose-Part Detection Program for the Primary System of Light-Water-Cooled Reactors," May 1981.

Tc=ts and inspections associated with this program will be performed in accordance with station procedures, maintenance work requests end/or outage work schedules as appropriate. All deviations from the program or deficiencies identified through the specified maintenance, cnlibration or testing activities are evaluated by Duke Power Company to determine if operability of the system has been affected and appropriate action taken.such as correcting the deviation or
