где Co, C - концентрация плутония в гексафториде урана до и после очистки, соответственно;
τ - время контакта гексафторида урана с сорбентом, с;
T - температура сорбента, K.1. A method of processing highly enriched uranium, including the oxidation of metallic uranium, obtaining a solution of uranyl nitrate, its extraction and sorption purification, denitration to obtain uranium oxides, fluorination of oxides to uranium hexafluoride suitable for producing low enriched uranium, and the return of oxides obtained from processing cinder to a fluorination stage, characterized in that the oxides obtained directly from the oxidation stage of uranium metal are directed to fluorination, the fluorination process is carried out to the content in the cinders 10 - 25% U of the fluorination feed, and the obtained highly enriched uranium hexafluoride is sent to purification of plutonium hexafluoride by selective sorption of the latter on sodium fluoride, while the contact time and process temperature are selected from the conditions determined by the equation
where Co, C is the concentration of plutonium in uranium hexafluoride before and after purification, respectively;
τ is the contact time of uranium hexafluoride with the sorbent, s;
T is the temperature of the sorbent, K.
