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
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

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.

A novel system for energy production is presented. This system has a modular composition of homogeneous reactors with H2O and 242mAm as a fuel. These reactors are spheres of 0.11-m radius and 1-MW(thermal) power and with a critical mass of 0.0201 kg of 242mAm.The advantages of homogeneous reactors are constant fuel reprocessing and constant refueling. As a result, there is a reduction of fission products, which improves the ratio of natural cooling to heat production with respect to a loss-of-control accident (LOCA) and other safety aspects. Homogeneous reactors also have a large negative temperature coefficient and small inherent excess reactivity during operation.The reactor concept we have presented for a very small, homogeneous reactor, further enhances the safety aspects in the case of a LOCA, because of a large surface-to-volume ratio.The improved safety, the simplicity, and the small volume should compensate for the use of an unconventional nuclear fuel.
