The key element of a Self-Consistent Nuclear Energy System is excess n
eutron generation. External neutron source is supposed to be included
in the nuclear energy structure to improve its neutron balance. The pa
per presents accelerator based 14 MeV neutron source that might contri
bute to neutron excess generation required for transmuting of those fi
ssion products which are difficult to transmute in ordinary fission re
actors. (C) 1997 Published by Elsevier Science Ltd.
