Conclusions
As a result of the calculations, it has been established that for nuclear reactors of power type the amount of232U formed depends significantly on the neutron-spectrum hardness, while for fast reactors operating on uranium fuel this amount is close to the quantity of232U obtained in reactors of water-cooled-water-moderated type with 3.6% enrichment. The comparison is made for the same235U burnup depth, and the difference in effective cross sections of the reaction (n, 2n) is disregarded.
To determine the absolute amount of232U accumulation, it is necessary to take account of the reaction (n, 2n).
