  • Cable reeving system
    Patent number: 4725398
    Abstract: A cable-driven arm-reciprocating system particularly useful for transferring nuclear fuel bundles from a nuclear reactor pool to a spent fuel storage pool, wherein an arm-retracting cable extends from a winch drum around fixed and movable-axis sheaves to a retracting anchor device and an arm-extending cable extends from the same winch drum also around fixed and movable-axis sheaves to an extending anchor device, each anchor device including spring means for maintaining and allowing for variations in cable tension.

  • Nozzle dam assembly
    Patent number: 4667701
    Abstract: In a nozzle dam assembly wherein a flange ring is affixed around a circular nozzle opening in a chamber wall, a support frame spans and is in non-threaded connection with the ring by releasable pins which carry under tension any load on the frame directed axially out of the nozzle into the chamber, and a circular dam with a sealing diaphragm disposed over it is attachable to the frame with its rim within the nozzle so that inflatable peripheral sealing means on the diaphragm effect the desired seal of the nozzle independent of the aforementioned axial load.

  • Nuclear reactor cavity decontamination machine
    Patent number: 4436694
    Abstract: Apparatus is disclosed for decontaminating the wall of a boiling water reactor cavity. A chassis on wheels is rollable on the refueling floor along the cavity curb. A pair of horizontal wheels roll against the curb. A support member extends upwardly and laterally from the chassis to clear the personnel handrail. A mast depends from the support member into the cavity and includes a horizontal reaction wheel bearing against the cavity wall. A vertically positionable carriage is mounted on the mast and carries water spray nozzles directed against the wall.
