Ratten, B W

The regulating rcd drive mechanism is actuated by a synchronous reluctance type linear electric motor located inside a tubular housing mounted on the head of the pressure vessel. The motor is partially submerged in primary coolant, but the windings are isolated from the water by means af seal welds. The moving part of the motor is called the rotor, although it actually moves in translation only. Motion is produced as the rotor seeks to follow the linear displacement of a magnetic field in exactly the same manner as the shaft of the shim rod drive motor follows a rotating field. The length of stroke of the rotor is plus or minus 23/4 in. about the neutral position; means are available, however, for increasing the amplitude to plus or minus 3 in. The motion of the rotor is directly transferred to the regulating rod through an interposed connecting rod. While the connecting rod is permanently bolted to the regulating rod, the rotor is attached to the connecting rcd by a bayonet type joint which permits connection or disconnection between these two parts as desired.
