摘要： A control rod drive system for a nuclear reactor that employs hydraulic cylinders to operate a conventional plunger/gripper drive system to incrementally move control rods into and out of the core of a reactor. The pressure differential for driving hydraulic pistons within the cylinders is obtained from the difference in pressure between the outside and inside of the core barrel of the reactor and control of the pistons is obtained from external solenoids attached to the reactor control system. The external solenoids regulate a charging pump feed to Poppet valves that control the hydraulic feed to the cylinders. A hydraulic piston/cylinder drive is also provided for the shutdown rods which operate in either an all in or out of the core condition.

摘要： Installations for mounting, controlling, and guiding control rods in and outside a vessel may be removed and passage through an upper internal part may thereby be avoided. An upper internal part is placed near the core of a reactor and laterally emerges on the outside of the vessel. All the transmission, control, and fluid systems pass through this internal part and emerge, by a mobile connection part, for each cluster of control rods, on an assembly head containing tanks of liquid neutron absorber, and injection circuits in injection channels placed between the fuel rods.

摘要： The present invention is a control rod guide tube cleaning apparatus in a nuclear reactor which comprises a rod member, one end side portion of which has the thickness such that the end side portion can pass through an inside of a connecting portion between a housing of a control rod drive mechanism and a control rod guide tube, a nozzle for sucking water, mounted on the rod member on the one end side so that the nozzle can go in and out of the rod member, a means for rotating the rod member in a horizontal direction, and a water passage for leading water sucked in the nozzle to an outside of the housing along the rod member. The rod member is inserted into the control rod guide tube through the inside of the housing. Then, the nozzle is rotated downward so that a suction port of the nozzle faces adjacently to the bottom inside the control rod guide tube. The nozzle is rotated in the horizontal direction by rotating the rod member in the horizontal direction. At the same time, dusts on the bottom inside the control rod guide tube is sucked by the nozzle together with water inside the control rod guide tube to discharge them out of the housing.

摘要： A hydraulic lock for latching a displacer rod drive mechanism in an up position. A piston having a truncated cone-shaped valve element is formed at an end of the drive rod. A complementary truncated cone-shaped valve seat is formed in the cap of the reactor housing. When the drive rod is activated to the up position, the valve element seats against the valve seat creating a seal and a pressure boundary. The piston is provided with piston rings. The pressure differential acting across the piston is transferred to the area of contact between the valve element and valve seat thus maintaining the drive rod in the up position and preventing leakage flow from around the piston rings. A hydraulic control system for operating the hydraulic latch is also disclosed.
