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.

New applications of space tethers (High-Voltage Tethered Satellite System project) are discussed in relation with idea1 of an active experiment in the Earth's radiation belts. Two conducting strings are supposed to be tethered between the main satellite and two small subsatellites flying through the ERB. A large potential difference ∼1MV is applied between the tethers by means of a generator carried on the main satellite. The tethers effectively scatter the high energy particles into loss cone of magnetic trap, providing a control of particle life time in ERB. The rigorous theory of the sheath layer formed by relatively cold plasma is developed, yielding the electric field profile, which is then used for the treatment of scattering problem. With the help of Fokker-Planck equation the average rate of particle losses, normalized per 1 km of the tether's length is found to be: (2.5 ÷ 14) · 1016 s−1 km−1 for electron belts and 1.8·1014÷2.5·1020 s−1 km−1 for proton belts. New active experiments in space become possible under the joint realization of HVTSS and HAARP projects.
