The world-wide discussion about the possibilities to transmute the waste from nuclear power stations has been on the increase in recent years. The main interest is on the reduction of the radiotoxity from actinide nuclei produced in thermal neutron capture by 238U. This cross section decreases with neutron energy, whereas fission increases
- and fission products are much less persistent in their radiation hazard. Experiments with fast neutrons and actinide targets are rather difficult, such that the challenge arises to improve the reliability of model predictions. Surprisingly the respective codes lack ingredients of nuclear theory, the importance of which has been worked out e.g. by spectroscopic studies. This will be exemplified using the breaking of shape symmetries.
