In a rod and tube type control device
WebThe most recent B&W design control rod drive mechanism (CRDM) is designated as type C. This type of mechanism is currently being used at Oconee Nuclear Station Unit II. It is similar in design to the type A and B mechanisms in use at other B&W facilities. The CRDM (Figure 6.1-1) consists of an electrically driven, roller nut assembly (rotor) WebA ram cylinder is a type of hydraulic cylinder that acts as a ram. A hydraulic ram is a device in which the cross-sectional area of the piston rod is more than one-half of the cross-sectional area of the moving components. Hydraulic rams are primarily used to push rather than pull, and are most commonly used in high-pressure applications. Read more

WebRod pumps are the most common form of artificial lift for oil wells. Today, these systems are used to lift formation fluids from more than 600,000 wells. A rod pump system consists of a prime mover, a surface pump, a sucker rod string and a downhole pump (Figure 1). The overwhelming majority of surface units are beam pumps.
WebFretting wear in a rod cluster control assembly (RCCA) is caused by vibration of the rodlets inside the guide cards during normal plant operation. It is a common concern in a pressurized water reactor design plant. Periodic inspection of the control rods is necessary to ensure structural integrity and maintain proper plant component functionality. WebAug 1, 1981 · Nuclear reactors are controlled by movable control rods made of neutron absorbing materials. These rods are driven by control rod drive mechanism which is directed by servo-control circuit. New drive mechanism was developed. Magnetic plunger connected with control rods in guide tube is exerted by the magnetic coil outside of the guide tube.
