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.

Norway’s Halden reactor takes first step toward decommissioning
The government of Norway has granted the transfer of the Halden research reactor from the Institute for Energy Technology (IFE) to the state agency Norwegian Nuclear Decommissioning (NND). The 25-MWt Halden boiling water reactor operated from 1958 to 2018 and was used in the research of nuclear fuel, reactor internals, plant procedures and monitoring, and human factors.

Our increasing need for safe, abundant, reliable, and carbon-free energy sources is stimulating renewed interest for employing nuclear energy to power our world. New materials and technologies that can address sustainability, cost, and waste issues of current water-based reactors is critical for realizing a future powered by the atom. Among these concepts is the utilization of molten salts as both the reactor coolant and as a fuel solvent, namely, the molten salt reactor (MSR). This workshop will provide an overview of the MSR concept and current technological challenges facing its development and deployment. On the experimental side, we will compare classical approaches to molten salt characterization with modern-day developments, with an emphasis on laser-based diagnostics. We will discuss the challenges associated with the modeling and simulation (M&S) capabilities, introduce the important physics spaces relevant to various MSR designs, and discuss the tight coupling of single physics modules to enable multi-physics simulation of the core and system.
