    Abstract: A tool for exchanging & transporting sample irradiation capsules(8) between a nuclear reactor vessel & swimming pool and between positions along the core heat shield includes an operating rod(30) movable relative to a vertical tube(4) and with a top handle(31) and lower end cam(37) to operate tongs(52,53) pivotable on the lower end of the tube. The tube forms the piston rod of a double-acting hydraulic jack which has a clamp mounted on its cylinder for pivoting about horizontal axes between an inoperative position & a position cooperating with a fixed part of the reactor. A 2nd clamp on the rod moves the clamp. The jack allows the tube to exert a downward thrust on a capsule.

    Abstract: The mechanism consists of a support which carries the control mechanism. There is a tubular element(8) in the support which forms a cage(14) over the entire width, and has several longitudinal grooves(15,16) to take free running rollers(17,18,19). A control rod(20) is mounted centrally on the tubular element over its entire length. The mechanism is motor driven and the central rod(20) is moved by a hydraulic cylinder(36).

    Abstract: A recirculating channel for the safety injection and spray circuit of a nuclear reactor is located between vertical walls and has a horizontal lower panel at the bottom of the gap, a pair of lateral horizontal solid upper panels (30) (31) supported by the walls (6), and vertical adjacent filter panel elements between upper and lower panels to define a pair of lateral and a central chamber (35) communicating through the filter elements. There is a central collecting chamber below the lower panel and outlets from it to the safety circuit.
