摘要:
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.
摘要:
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.
