摘要：A device for removing a radioactive deposition from a fuel assembly (1) in a nuclear plant comprises a container (2), arranged to accommodate the fuel assembly, first means (3, 4, 5), arranged to feed a fluid into and through the container (2), said fluid being provided to release the deposition from the fuel assembly (1) by means of abrasion and transport radioactive deposition material out of the container (2) and second means (6, 7) being arranged to receive the radioactive material transported out of the container (2) by the fluid. In the device, at least second means (6, 7) are arranged in a gamma -radiation-dampening medium.
