Neutron Cross-Section Measurements on 103Rh and 133Cs for Improved Nuclear Criticality Safety

New transmission and capture cross-section measurements were performed at GELINA for 103Rh and 133Cs. These experiments are part of a series of measurements that are planned to improve the evaluations of the nuclear data for the present nuclear power plants and for criticality safety of spent fuel storage and transport. The detection system was based on C6D6 detectors for the neutron capture experiment and on 6Li-glass detectors for the neutron transmission experiment. Samples with different thicknesses were used. The useful energy range for this experiment was from 20 eV to about 150 keV. In the Resolved Resonance Region (RRR) a resonance shape analysis was done with the code REFIT [1], while in the Unresolved Resonance Region (URR) the data was interpreted in terms of average resonance parameters.
