METHOD OF EXTRACTION OF THE TARGET COMPONENTS GAINED AS A RESULT OF IRRADIATION AND A DEVICE FOR ITS REALIZATION Russian patent published in 2005 - IPC

FIELD: nuclear engineering; methods and devices for extraction of the target components gained as a result of irradiation.

SUBSTANCE: the invention is pertaining to the field of nuclear engineering. The method of extraction of the target components gained as a result of irradiation consists, that the target supplied on its both ends with the unions with diaphragms is hermetically connected directly into a flow-through link of a process flowsheet. Then by means of the unions of the pusher rods they destroy the diaphragms so integrating the internal cavities of the shell and the process flowsheet. First gate through the shell of the target the liquid or reactants for extraction of the target components. Then the shell with the left in it products disconnect from the processing line and shut from its ends by the sealing threaded stops for temporary or constant storing. The device for extraction of the target components gained as the result of the irradiation consists of a shell with the irradiated material and contains the unions - pusher rods hermetically fixed on it from both ends and made in the form of cylindrical branch pipes with the blind diaphragms inside, the threading on the outer surface and flutes on the butt surfaces for placement in them of elastic process flowsheets. The connecting elements of the flow line of the process flowsheet have the pushers for destruction of the diaphragms actuated by the sleeve nuts. The advantages of the invention consist in simplification of the process, reduction of the processing operations and exclusion of pollution of the protective chamber by the radioactive substances.

EFFECT: the invention ensures simplification of the process, reduction of the processing operations and exclusion of pollution of the protective chamber by the radioactive substances.
