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.

Securing the advanced reactor fleet
Physical protection accounts for a significant portion of a nuclear power plant’s operational costs. As the U.S. moves toward smaller and safer advanced reactors, similar protection strategies could prove cost prohibitive. For tomorrow’s small modular reactors and microreactors, security costs must remain appropriate to the size of the reactor for economical operation.

Supersonic Molecular Beam Injection (SMBI) experiments were performed at GAMMA 10 device under the collaboration with HELIOTRON Group of Kyoto University. In order to survey the effects of SMBI on the plasma behavior, we measured the plasma radiation by using the ultraviolet and visible (UV/V) spectroscopic system and study behavior of the neutral hydrogen and impurity ions emissions with using the collisional-radiative model (CR-model).With SMBI, the neutral hydrogen density calculated by the CR-model was about 20 times larger than that without SMBI. Impurity densities of oxygen ions also increased with SMBI.
