摘要： A method for removing and installing a control rod drive from a drive housing mounted in the vessel of a boiling water reactor. The method comprises having a carriage supported by and movable along the service rails normally present in the undervessel cavity, and a cradle pivotally connected to the carriage and having a length substantially less than the length of a control rod drive. The pivot point between the cradle and the carriage is chosen such that the length of the carriage is subsumed within the length of the cradle when the cradle is pivoted into a horizontal position. The pivoting movement is accomplished by means of a hydraulic cylinder connected between the upwardly swinging end of the cradle. The carriage includes a lifting and lowering mechanism formed by the combination of a leadscrew drive and a hydraulic cylinder. The hydraulic cylinder is connected to the cradle so that it is movable between a recess within the cradle when not in use, to a position directly beneath and in tandem with the control rod drive when in use. The lifting and lowering mechanism can move a control rod drive an installed position within a drive housing without the need for installation of special end effectors or other components.

摘要： Both a system and a method for converting two AGTAW welders into a AGMAW welder is provided. The system generally comprises a MIG weldhead for replacing the TIG weldhead of one of the AGTAW welders, a pulser multiplier circuit for increasing the frequency of the power supply output current from 10 to between 300 and 800 pulses per second, and a wire feed motor and motor control circuit capable of feeding weld wire at a rate compatible with a AGMAW welding operation. In the method of the invention, the control circuit assembly of one of the AGTAW welders is connected in parallel to the power supplies of both of the two AGTAW welders, and the outputs of these power supplies are likewise connected in parallel. The TIG weldhead of one of the AGTAW welders is replaced with the MIG weldhead, and the pulser multiplier circuit is selectively connected to the current pulser of the single control circuit assembly which controls both power supplies. Next, the existing wire feed motor and motor control circuit of one of the AGTAW welders is replaced with the high-feed rate motor and control circuit of the system. Finally, the upslope and downslope circuit and the arc voltage response circuit which are normally present in the programmer of the control circuit assembly of one of the AGTAW welders is converted into a AGMAW burnback circuit in order to prevent weld wire from the wire feeder from fusing into the weld puddle.
