Abstract

Abtract—The possibility was shown of using a thin-film rotary apparatus for the preparation of dry precursor salts in the form of ammonium uranyl nitrate and uranyl formate containing up to 5 wt % low-background plutonium. Dioxide powders obtained after the thermal decomposition and reduction of the salts are represented by a solid solution (U0.95Pu0.05)O2 in both cases. Based on the analysis of the amounts of secondary radioactive waste (RAW), specific surface areas of powders, and particle shapes, it was decided to continue elaboration of the process using highly active uranium-plutonium solutions and formic acid.

用薄膜旋转装置制备氧化铀和钚混合粉末
摘要:表明了用薄膜旋转装置制备含有5 wt %低本底钚的硝酸铀酰铵和甲酸铀酰铵形式的干前驱盐的可能性。在这两种情况下,盐经过热分解和还原后得到的二氧化氮粉末由固溶体(U0.95Pu0.05)O2表示。根据对二次放射性废物(RAW)的数量、粉末的比表面积和颗粒形状的分析,决定继续使用高活性铀-钚溶液和甲酸来详细说明这一过程。
