A process for separating ceramic nuclear fuels out of metallic support members or support member parts in which there adhere the nuclear fuels, especially subsequent to the burning down of the nuclear fuels in nuclear reactors. The ceramic nuclear fuels are washed off from the support member or carrier member part by means of a liquid jet which stands under a high pressure. The liquid jet is directed against the nuclear fuel, and the pressure of the liquid is set so high, that the nuclear fuel which adheres to the support member is completely removed. The liquid jet finds the transition from the ceramic nuclear fuel to the metallic support member material such that, even at a swelling of the fuel rod, and deformation of the support member part, there is achieved an efficient detaching of the nuclear fuel. The metallic support members or support member parts hereby remain intact and are segregated after the washing off of the nuclear fuel. Only the nuclear fuel fragments are introduced into the chemical solvent.
