US NRC Generic Letter GL 89-10 was issued in part because of concerns regarding the continued functional capability of safety-related motor-operated valves (MOVs) at nuclear facilities. There the ability of motor-operated valves to perform their intended functions (i.e., pressure boundary retention, open and close operation, flow sealing) following loads in excess of design basis load capacities is reviewed. General criteria applicable to the evaluation of such conditions are discussed along with application to selected typical valve components. Structural and functional limits are discussed.
