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.

Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.

The Osiris reactor concept is one of two that emerged from the DOE-sponsored IFE reactor design study. It uses a heavy ion beam driver, a carbon cloth first wall and blanket structure that is filled with Flibe, and a steam power conversion system. The driver energy is about 5 MJ and the target yield is about 430 MJ. A 1000 MW(e) net plant requires a rep rate of about 4.6 Hz. The reactor chamber is of a leak-tolerant design where Flibe permeates a carbon cloth first wall and provides a protective coating. A Flibe spray, which supplies the pool at the bottom, condenses blowoff vapor. All components are removed as an assembly from the top of a carbon composite vacuum vessel. The study included assessments of environmental and safety aspects, economics, and technology development requirements.
