ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.

Can hydrogen be the transportation fuel in an otherwise nuclear economy?
Let’s face it: The global economy should be powered primarily by nuclear power. And it probably will by the end of this century, with a still-significant assist from renewables and hydro. Once nuclear systems are dominant, the costs come down to where gas is now; and when carbon emissions are reduced to a small portion of their present state, it will become obvious that most other sources are only good in niche settings. I mean, why use small modular reactors to load-follow when they can just produce that power instead of buffering it?

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.
