FIELD: metallurgy. n SUBSTANCE: invention relates to metallurgy and can be used during recycling and disposal of the spent nuclear fuel. Method includes americium extraction from nitric water phase by means of its circulation in the first extractor, washing of the obtained organic phase in the second extractor, and selective reextraction of the americium in the third extractor. Then the lanthanides reextraction is performed from the obtained phase by means of its circulation in the forth extractor. n EFFECT: selective extraction of the americium is ensured from the nitric water phase containing americium, curium and fission products including lanthanides and yttrium, and optionally containing uranium, plutonium and neptunium in trace quantities. n 23 cl, 2 dwg, 10 tbl, 3 ex |
