Physics features comparison of TRU burners: Fusion/Fission Hybrids, Accelerator-Driven Systems and low conversion ratio critical fast reactors

This paper compares different types of TRU burners, sub-critical (as Accelerator-Driven Systems and Fusion Fission Hybrids) but also critical, low conversion ratio, fast reactors. To make a significant comparison, it is specified for which objective and within which strategy these systems can be envisaged. Beside intrinsic cost parameters, the associated fuel cycle issues can prove to be crucial for their deployment.
