Abstract
The scientific-research work on reprocessing spent oxide fuel by gas-fluoride method is reviewed. The refining possibilities of the basic stages of gas-fluoride technology are studied. The possibility of separating most fission products from the ashes at the fluoridation stage is confirmed experimentally. The use of fluoride sorbents (NaF, BaF2) permits reaching a total coefficient of removal of fission products from UF6 at the 107 level. It is shown that deep extraction of plutonium from oxide fuel is possible. The results of investigations on pyrohydrolysis of UF6 and a mixture of UF6 with PuF6 with production of granulate of the oxides with the required density with fluorine content 0.005 mass % and oxygen coefficient 2–2.1 are presented.
Recommendations for use of gas-fluoride technology for reprocessing spent oxide fuel from fast and light-water reactors are given taking account of the new requirements for nonproliferation of fissioning materials, and a prediction is given for a closed nuclear fuel cycle using gas-fluoride technology and separation of Np, Am, and Cm for transmutation with the aid of easily melting fluoride melts. 1 figure, 5 tables, 27 references.
