GROUPING OF HLW IN PARTITIONING FOR B T (BURNING AND/OR TRANSMUTATION) TREATMENT WITH NEUTRON REACTORS BASED ON 3 CRITERIA/

A grouping concept of HLW in partitioning for B/T (burning and/or tran smutation) treatment by fission reactor was developed in order to impr ove the disposal in waste management from the safety aspect. The selec ting and grouping concept was proposed herein, such as Group MA1 (Np, Am, and unrecovered Ll and Pu), Group MA2 (Cm, and trace quantity of C f, etc.), Group A (Tc and I), Group B (Cs and Sr) and Group R (the par titioned remains of HLW), judging from the three criteria for B/T trea tment, based on (1) the concept of the potential risk estimated by the hazard index for long-term tendency based on ALI, (2) the concept of the relative dose factor related to the adsorbed migration rate transf erred through ground water, and (3) the concept of the decay accelerat ion factor, the burning and/or transmutation characteristics for recyc le B/T treatment.
