ABSTRACT:
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.
