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.

Hydrogen generators that use a proton exchange membrane (PEM) cell stack for water electrolysis have various applications, one of them being combined electrolysis catalytic exchange installations. This process separates a stream of tritiated water into detritiated water and a stream of tritium-enriched hydrogen. The stream of tritium-enriched hydrogen then can be used in tritium recovery processes. The development of hydrogen generators capable of processing tritiated water still arouses increased interest due to their low commercial availability. This paper presents the construction of a hydrogen generator compatible with tritium in a two-PEM cell stack configuration in terms of instrumentation and control as well as the active safety measures implemented.
