Self-Consistent Nuclear Energy System simultaneously satisfying four o
bjectives: energy generation, fuel breeding, transmutation of radionuc
lides and system safety has been proposed as a new phylosophical basis
for further nuclear development. Transmutation of radionuclides is cl
osely connected with the key element of Self-Consistent option - exces
s neutron generation which is assumed to be provided by external neutr
on source. The paper presented makes a special emphasis on excess neut
ron generation in fusion neutron source based on DD plasma. (C) 1997 P
