Abstract:It is well known that fission reactors are energy rich and neutron poor, while fusion reactors are neutron rich and energy poor. As a result, it may be desirable to use the neutrons produced by a fusion reactor operating at a multiplication factor Q ~ 1 to breed fissile material in a blanket, which can also undergo fission reactions with the fast neutrons to produce power. We examine this approach in conjunction with a bi-modal fusion propulsion system which, upon reaching destination, is operated primarily as… Show more
