SUMMARY:Transmutation of nuclear waste: Basics\, Methods\, Perspective
s\, NPAC (Nuclear/Particle/Astro/Cosmo) Forum\, Arnd Junghans\, Instit
ut für Strahlenphysik\, Helmholtz-Zentrum Dresden-Rossendorf
DESCRIPTION:Nuclear power production having the merit of very little g
reenhouse gas emissions accumulates high-level radioactive waste. Curr
ently final storage solutions in deep geological formations are in pre
paration in many countries having a nuclear fuel cycle to safely keep
the spent nuclear fuel for up to a million years. Nuclear reactors usi
ng a fast neutron spectrum can fission essentially all long-lived acti
nides (e.g. Plutonium) and thus transmute the long-lived actinide nucl
ides into generally short lived fission products. Generation IV nuclea
r reactor concepts and accelerator driven systems (ADS)are currently i
n development that foresee a closed fuel cycle. The majority of the fi
ssile nuclides (Uranium\, Plutonium) shall be used for power generatio
n and only fission products will be put into final storage that needs
to last for only 1000 years because of the shorter nuclear half-lives.
For the transmutation of high-level radioactive waste a lot of resear
ch and development is still required. One aspect is the precise knowle
dge of nuclear data for reactions with fast neutrons. Nuclear reaction
s relevant for transmutation are investigated at the photoneutron sour
ce nELBE at Helmholtz-Zentrum Dresden-Rossendorf in Dresden\, Germany.
