The role of a magnetic effect in uranium isotope fractionation

The impact of a magnetic isotope effect on the reactions of radical pairs containing radical ions with a heavy atom (UO 2 2+ ) has been studied; in the future, the findings can be used to solve practical problems involving a new method of enrichment of uranium isotopes in chemical reactions owing to differences in their magnetic properties. The magnetic isotope effect of uranium can be the basis for an effective method of separating uranium isotopes (234U, 235U, 238U). Based on the theoretical and experimental studies, the specific features of the behavior of natural and artificial uranium isotopes in chemical reactions attributed to the fundamental properties of their nuclei and the possibility of using both waste of enriched uranium ores (tailings in tailing ponds) and spent nuclear fuels as a nuclear fuel have been substantiated. The behavior of natural and artificial even isotopes of the isotope mixture in a nuclear fuel (232U, 234U, 236U), which are harmful impurities that absorb a portion of thermal neutrons and worsen the homogeneity of the fuel, has been studied.
