Division Spotlight
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

Measurements of neutron total cross sections of palladium in the energy region from 0.2 to 120 eV have been performed by using the time-of-flight method at the Pohang Neutron Facility. A group of high-purity natural palladium metallic plates with thicknesses of 0.5 and 1.0 mm is used for the neutron transmission measurement. Resonance parameters of 104Pd, 105Pd, 106Pd, 108Pd, and 110Pd in the neutron energy range below 120 eV were extracted from the transmission ratios by using the multilevel R-matrix SAMMY code. The present results are compared with the evaluated data from ENDF/B-VII.1 and previous experimental data. The statistical analysis for nearest-neighbor level spacings in 105Pd has been carried out to compare with the Wigner distribution.
