摘要： A method for testing whether fuel rods of fuel assemblies resting on a working base and under water, of a nuclear reactor are leaking is disclosed. The method includes heating at least one first fuel assembly of a first division of fuel assemblies for driving radioactive fission products out of a defective fuel rod contained in the first fuel assembly. The first fuel assembly is continuously tested by extracting samples of water and continuously degassing the water removed from an area around the first fuel assembly even during the heating resulting in gas. A radioactivity of gaseous fission products released in the gas is continuously recorded. A fuel assembly belonging to a second division of fuel assemblies is heated only if the first fuel assembly belonging to the first division of fuel assemblies has been tested. An apparatus for implementing the method is also disclosed.

摘要： A method for shredding and packing used structural elements of nuclear reactors, such as fuel assembly cases, comprises the steps of shredding structural elements to scrap pieces; flushing the scrap pieces in a transport container and flushing away highly radioactive particles of foreign matter and collecting the particles in the interior of the transport container; packing the flushed scrap pieces around the particles of foreign matter collected in the interior; and inserting the packed transport container into a sealable disposal container. An apparatus for performing the method includes a shredder assembly, an interchangeable transport container disposed below the shredder assembly; connectors for connecting the transport housing in a liquid cycle; a filter disposed in the liquid cycle; a carriage for laterally displacing the transport container relative to the shredder assembly; and lifting and transportation devices for lifting the transport container and for inserting the transport container into an ultimate disposal container.

摘要： A method for packaging, compacting or storing spent control and absorber elements of light-water reactors for waste disposal, a device for preparing an elongated component of a spent control element, a light-water-cooled reactor and a coil of an originally elongated component are provided for storing absorber fingers or absorber sheets of spent control elements in storage containers in pressurized-water reactors or boiling-water reactors. The absorber fingers or absorber sheets are separated from the control elements. They are not cut into pieces (in which process large amounts of radioactive substances would be released), but instead they are only deformed, namely wound into coils which can be stacked in a space-saving manner in the storage containers.
