METHOD OF PREPARING URANIUM OXIDE POWDERS WITH DESIRED URANIUM-235 CONTENT
production of nuclear fuel. SUBSTANCE: method involves mixing uranium-containing powders with different content of uranium-235. All powder volume with high content of uranium-235 and part of powder with low content of uranium-235 are mixed and prepared mixture is dissolved in nitric acid. Ammonium p...

All powder volume with high content of uranium-235 and part of powder with low content of uranium-235 are mixed and prepared mixture is dissolved in nitric acid. Ammonium polyuranates are precipitated with ammonia, dried and calcined. The obtained product is mixed with remained part of powder with low content of uranium-235 and reduced in hydrogen medium. EFFECT: improved method of preparing, decreased consumption of labor intensity and materials. 3 cl, 3 tbl |
