Abstract
1. Способ растворения МОКС-топлива в растворе азотной кислоты с использованием фтор-иона и гадолиния, отличающийся тем, что растворение осуществляют при одновременном присутствии в растворе ионов фтора и гадолиния при следующих концентрациях в растворе: азотной кислоты (6-9) моль/л, фторида натрия (0,05-0,08) моль/л и нитрата гадолиния в пересчете на гадолиний (1,3-1,5) г/л. ! 2. Способ по п.1, отличающийся тем, что растворяют топливо состава: диоксид природного урана UO2 74-76 мас.%; диоксид оружейного плутония PuO2 24-26 мас.%, которое было получено плазмохимической денитрацией раствора азотнокислых солей урана и плутония. ! 3. Способ по п.1, отличающийся тем, что растворение осуществляют в течение трех суток при температуре 20-25°С, после чего к нерастворившемуся остатку приливают новую порцию раствора. 1. A method of dissolving MOX fuel in a nitric acid solution using a fluorine ion and gadolinium, characterized in that the dissolution is carried out with the simultaneous presence of fluorine and gadolinium ions in the solution at the following concentrations in the solution: nitric acid (6-9) mol / l , sodium fluoride (0.05-0.08) mol / l and gadolinium nitrate in terms of gadolinium (1.3-1.5) g / l. ! 2. The method according to claim 1, characterized in that dissolve the fuel composition: natural uranium dioxide UO2 74-76 wt.%; weapons-grade plutonium dioxide PuO2 24-26 wt.%, which was obtained by plasma-chemical denitration of a solution of nitric acid salts of uranium and plutonium. ! 3. The method according to claim 1, characterized in that the dissolution is carried out for three days at a temperature of 20-25 ° C, after which a new portion of the solution is poured to the undissolved residue.
