URANYL FLUORIDE-BASED SORBENT AND METHOD OF ITS PRODUCTION

摘要

FIELD: process engineering. ^ SUBSTANCE: invention relates to production of sorbents used for treatment of uranium hexafluoride made from irradiated nuclear fuel to remove plutonium heaxafluoride. Proposed sorbent comprises uranyl fluoride and additive to increase sorbent porositity selected from fluorides of calcium, magnesium, strontium and barium in amount of 5-25 wt %. Said sorbent is produced on mixing uranyl fluoride and aforesaid additive. Obtained mass is formed and dried at 20-25C on heating in 75C, 120C and 150C steps. ^ EFFECT: sorbent high-porosity strong granules. ^ 2 cl, 1 ex, 1 tbl
