Behavior of fission products in simplified solvent extraction system for uranium, plutonium and neptunium co-recovery

Nakahara, Masaumi; Shibata, Atsuhiro ; Koma, Yoshikazu

To elucidate the behavior of fission products, two counter current experiments were carried out with a dissolver solution derived from irradiated fast neutron reactor "JOYO" core fuel, one was a single cycle flow sheet using double scrubbing solution with 9 and 1 mol/dm $^{3}$ HNO $_{3}$ and the other used a Tc scrubbing solution with 10 mol/dm $^{3}$ HNO $_{3}$ . Among fission products, the decontamination behavior of Zr and Tc differed according to HNO $_{3}$ concentration of the scrubbing solutions. The decontamination factor of Zr and Tc increase to 76.8 and 7.52 with 10 mol/dm $^{3}$ HNO $_{3}$ in the Tc scrubbing solution. Other fission products such as Cs was well decontaminated and its DF resulted in 10 $^{5}$ .
