Abstract

In the search for transmutation concepts, accelerator driven sub-critical actinide and isotope incinerators have attracted a great deal of attention. One reason is the fact that actinide fuelled (critical) reactors pose a particular problem of control as they are characterised by a small delayed neutron fraction coupled with a small Doppler effect and a positive void coefficient. In this context one point kinetic studies have been performed dealing with fast transients as a function of reactivity insertion in accelerator driven systems. These show that such boosters behave quite benignly even if they are only slightly subcritical. A new formula relating the accelerator energy requirements with the amount of fission product transmutation and the multiplication factor of the system has been developed.
