In electronuclear systems with high neutron multiplication factors of K-eff
>0.94 where the heat generation due to fission reactions essentially exceed
s that obtained due to the driving beam of accelerated particles ionization
losses appear to be relatively less significant. This makes possible the u
se of proton and light ion accelerators with energies of just about several
hundred MeV which significantly simplifies the system, makes it cheaper an
d provides the possibility of producing much higher currents than those pro
duced by high energy machines.
