Abstract: A process for producing an absorber element, includes applying an absorber layer having an amorphous, metallic base material containing at least one neutron-absorbing element to a support element. The base material, apart from impurities, is formed of nickel, silicon, chromium, iron, at least one neutron-absorbing element and at least one dopant. The absorber layer is formed from at least one foil or at least one sheet which is applied to the support element, in particular by welding. A particularly suitable welding process is the Nd:YAG laser welding process. An absorber element and an absorber structure are also provided.

Abstract: An absorption structure for absorbing neutrons and a method for producing the absorption structure include placing a neutron-absorbing material between a first sheet and a second sheet. The sheets are joined together and a plurality of voids is formed between them for receiving the neutron-absorbing material. At least one of the sheets has struts or bulges forming the plurality of voids and creating a material bond with the second sheet. The introduction of the neutron-absorbing material into the voids with a virtually arbitrary concentration also makes it possible to adjust the absorption capacity of the absorption structure within wide limits.

Abstract: Device for disposing of elongated core instrumentation probes from nuclear reactors, the device having a guide for the probes to be disposed of, shears for cutting the elongated probes into sections and a shroud for receiving the sections, including a shielded storage container, the guide including a switch for bypassing the shroud, and means for controlling the switch together with the shears for directing relatively long probe sections having a relatively low radiation level into the shroud, and for cutting probe parts having a relatively high radiation level into manifold shorter sections and guiding the manifold shorter sections of the probes having the relatively high radiation level into the storage container.
