The feasibility of using D–3He and D–D fusion fuels

A careful study of the conditions required to burn D-3 He and D-D fuels in a fusion reactor, with realistic models for bremsstrahling and synchrotron radiation losses, shows that the low reactivity of D-3 He and D-D fusion reactions severely restricts the choice of fuel mixtures that can be brought to ignition and requires very low levels of impurities and alpha particle ash, with plasma temperature, density, beta and energy confinement time that are far beyond the capability of any known magnetic confinement system.The fuel mixtures of D-3 He and D-D that can be brought to ignition produce large fluxes of neutrons and there are serious problems with fuel cycles and reserves.
