In spent nuclear fuel (SNF) reprocessing technology, the hydrometallurgical scheme in the version of the classic PUREX process was today accepted. However, in this case mass-transfer operations require significant aqueous flows. The volume of these streams subsequently becomes a liquid radioactive waste (LRW). The reducing of the waste solutions volume in the general SNF recycling process, with the following minimizing of LRW volume, was based on the use of alternative mass-transfer process - liquid chromatography (LC). Uranium-plutonium extract purification by LC process in the simulating SNF reprocessing process was carried out. The dynamic experiments on a laboratory glass column packed with a porous granular high surface material were successfully performed, and the effectiveness of the purification process was evaluated. On the laboratory liquid chromatography column (LCC), a series of dynamic experiments were carried out in order to obtain the original data for the design of a pilot unit.
