摘要： Refueling of a nuclear reactor (40) includes removing a fuel assembly (10). The removal method includes lowering a lifting tool (80) of a crane (44) onto a top of the fuel assembly. The lowered lifting tool including a plurality of downwardly extending elements (82) that surround and vertically overlap a portion (74) of a control rod assembly (70) extending above the top of the fuel assembly. The downwardly extending elements are locked with corresponding mating features (26) at the top of the fuel assembly to connect the lifting tool with the fuel assembly. The connected fuel assembly is moved into a spent fuel pool (42) using the crane, and the lifting tool is disconnected from the top of the fuel assembly by unlocking the downwardly extending elements from the corresponding mating features at the top of the fuel assembly.

摘要： A load compensating device (15) for a nuclear fuel element handling machine has : a frame (16) fitted to a fixed supporting structure (13); a slide (17), which runs along the frame (16) and is attached to a hoisting member (6) such as a cable; a first and second fluid-operated piston device (18a, 18b) connected mechanically in series to each other and to the slide (17); and an operating fluid feed circuit (19) for parallel-feeding operating fluid to the piston devices (18). The first piston device (18a) is designed to keep the tension of the hoisting member (6) above a given minimum value (T min ); and the second piston device (18b) is designed to keep the maximum tension of the hoisting member (6) below a given maximum value (T max ).

摘要： The invention refers to a device and a method for handling a fuel assembly (3), which comprises a number of fuel rods extending between a lower part and an upper part of the fuel assembly, a debris filter located in the lower part of the fuel assembly and a casing surrounding the fuel rods. The device comprises a lifting device (15) for engaging, during a lifting operation, a fuel assembly located in a reactor vessel (1) and lifting the fuel assembly upwards and out from the reactor vessel. A conduit member is connected to the upper part of the fuel assembly. A pump (32) creates a flow of water through the conduit member and the fuel assembly during the lifting operation. The flow has such a size that possible debris particles contained in and/or immediately beneath the debris filter at least are retained in and/or immediately beneath the debris filter during the iifting operation.
