The neutron source

In most hybrid reactor concepts, the external neutrons are provided by the interaction of accelerated charged particles with matter. The most widely proposed systems use high-energy protons. A few other propositions resort to electrons or deuterons as well as muons as originators of neutron — producing reactions. Because of the importance of high-energy protons we discuss this case more thoroughly.

Dry processes

Organic solvents suffer significantly from radiolysis. Therefore, before reprocessing they require sizeable cooling times of the spent fuels. Typical cooling times, such as those used at the COGEMA The Hague plant, are of the order of 5 years although cooling times as short as 1 year have been considered [138]. Shorter cooling times lead to a shorter lifetime of the […]

Cost estimates

Not many cost estimates of hybrid reactors are available. It is, however, interesting to check whether the adjunction of a high-intensity accelerator to a reactor would not lead to an unacceptable cost increase. In this respect, although there are obviously large uncertainties, the CERN group cost estimate of its proposed Energy Amplifier [162] is interesting. The IEPE of Grenoble [53] […]
