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.

Fabrication milestone for INL’s MARVEL microreactor
A team from Idaho National Laboratory and the Department of Energy’s Office of Nuclear Energy (DOE-NE) recently visited Carolina Fabricators Inc. (CFI), in West Columbia, S.C., to launch the fabrication process for the primary coolant system of the MARVEL microreactor. Battelle Energy Alliance (BEA), which manages INL, awarded the CFI contract in January.

Assemblies have been built for measuring gamma rays from coal following the capture of neutrons from 252Cf. Sources of sizes to 60 μg of calcium 1.4 × 108 n/s were used. Paraffin moderated the fast neutrons, and beryllium metal was useful as a reflector. The gamma-ray spectrum from a Ge(Li) detector showed that the line intensities of a number of elements (e.g., hydrogen, iron, sulfur, and silicon) could be used to determine concentrations. The aim was to explore possible application in planned coal conversion plants.
