Neutron-Driven Element Transmuter
Abstract
A beam of protons from a particle accelerator used to produce neutrons which are fired in an appropriate lead assembly. Neutrons bounce around inside the lead, losing a little energy with each bounce, such that the neutron spectrum covers a broad range of energies. Lead being the most transparent element to high energy neutrons has the advantage that these are not absorbed by lead, but much more efficiently by atoms of the sample to be transmuted. This enhanced neutron exposure may be used to produce useful radio-isotopes for medical use or, when using an opposite procedure to the one used for isotopes production, to transmute long lived isotopes such as those recovered from spent nuclear fuel.
