Rпром-R= (5-20),
где Rпром - содержание урана-235 в смеси после предварительного смешивания;
R - требуемое содержание урана-235 в конечном продукте,
а оставшуюся часть порошка с низким содержанием урана-235 смешивают с обработанным продуктом.1. A method of producing powders of uranium oxides with a given uranium-235 content, consisting in the fact that uranium-containing powders with high and low uranium-235 contents are pre-mixed, then dissolved in nitric acid and ammonium polyuranates are precipitated with ammonia, followed by drying, calcining by grinding the treated product in a hydrogen environment, characterized in that all the powder with a high content of uranium-235 and a part of the powder with a low content of uranium-235 are sent to the preliminary mixing; keeping uranium-235 in the mixture after premixing based on the condition:
Rprom-R = (5-20),
where Rprom - the content of uranium-235 in the mixture after premixing;
R is the required content of uranium-235 in the final product,
and the remainder of the low uranium-235 powder is mixed with the processed product.
