Division Spotlight
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.
Meeting Spotlight
Nuclear Energy Conference & Expo (NECX)
September 8–11, 2025

All cross sections, energy spectra, and double-differential cross sections of six outgoing particles (neutron, proton, deuteron, triton, 3He, and alpha particle) for the p+90Zr reaction are consistently calculated and analyzed at incident proton energies below 200 MeV by using nuclear theoretical models. The optical model; distorted wave Born approximation theory; the intranuclear cascade model; the exciton model; Hauser-Feshbach theory and the evaporation model; and, especially, the improved Iwamoto-Harada model of light composite particle (deuteron, triton, 3He, and alpha-particle) emission have been included in the calculation, which is in good agreement with the experimental data.
