Nuclear Data for Transmutation

Americium fission-capture cross sections

Thermal neutron spectrum:

  • Neutron capture dominates fission
  • Production of long lived actinides

Fast neutron spectrum:

  • Neutron induced fission dominates
    neutron capture
  • All actinides can undergo fissíon

Partitioning and Transmutation of spent nuclear fuel can reduce the long-lived radioactivity in a final repository.   

We investigate the physics of transmutation with the time of flight facility nELBE.

Extending the scope of  accurate nuclear data:

Design and safety studies of innovative nuclear systems and the development of transmutation technologies require the measurement and evaluation of accurate nuclear data for the corresponding nuclear reactions. The new neutron time-of-flight facility nELBE and the bremsstrahlung source γELBE are dedicated to study these reactions and improve our understanding of the fundamental physics underlying the transmutation process. This research is conducted in close collaboration with international partners. The FP7-Euratom project ERINDA has been coordinated by HZDR.
