High-level radioactive material treatment system and high-level radioactive material treatment method

摘要

PROBLEM TO BE SOLVED: To extract a minor actinide with low process load and high workability. SOLUTION: This is a high level radioactive substance processing apparatus for treating a high level radioactive substance containing a minor actinoid, and supplies a liquid supply unit for supplying a liquid containing the high level radioactive substance and an extractant for an organic phase. The extractant supply unit, the diluent supply unit that supplies the diluent, the liquid, the extractant, and the diluent are mixed, and at least one of the minor actinoid and the lanthanoid contained in the high-level radioactive substance is extracted into the extractant. The diluted solution contains the MA extract generating unit and the diluted solution having a boiling point of 100 ° C. or lower. [Selection diagram] Fig. 1
