Toxicity reduction in accelerator-driven transmutation systems with molten salt cores

Two accelerator-based transmutation systems with molten salt cores are analysed: the ATW system proposed by Los Alamos and the JAERI molten salt system. The toxicity reductions achieved in each system with respect to an open fuel cycle are assessed. Additionally, individual nuclide toxicity reduction calculations are performed allowing to compare both systems on a consistent basis despite the differences in the fuel cycle strategies (the ATW system burns transuranics from LWRs and the JAERI molten salt system operates in a 'double strata fuel cycle'). 8 refs., 2 figs., 4 tabs
