MARVEL PDSA approval could serve as blueprint
MARVEL, the Microreactor Applications Research Validation and Evaluation project at Idaho National Laboratory, has had its preliminary documented safety analysis approved by the Department of Energy, marking a milestone in its development and serving as a potential outline for other microreactors in development.

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.
