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
Thermal Hydraulics
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.

ARPA-E announces $40 million to develop transmutation technologies for UNF
The Department of Energy’s Advanced Research Projects Agency–Energy (ARPA-E) announced $40 million in funding to develop cutting-edge technologies to enable the transmutation of used nuclear fuel into less-radioactive substances. According to ARPA-E, the new initiative addresses one of the agency’s core goals as outlined by Congress: to provide transformative solutions to improve the management, cleanup, and disposal of radioactive waste and spent nuclear fuel.

Nuclear power is currently the single largest carbon-free source of electricity in the United States. The climate mitigation cost savings of the existing U.S. nuclear fleet is denominated in hundreds of billions of dollars [net present value (NPV)] based on an integrated assessment modeling of the U.S. energy system within a globally consistent framework. Lifetime extensions of the existing nuclear fleet from 40 years to 60 and 100 years resulted in $330 billion to $500 billion (all figures are in U.S. dollars) (NPV) of mitigation cost savings for the United States under a deep decarbonization scenario consistent with limiting global temperature change to 2°C. The addition of new nuclear deployments in the United States increased the total U.S. mitigation cost savings of the 2°C climate goal by up to $750 billion (NPV). Immediate actions are required in the United States and globally to achieve net-zero carbon emissions by mid-century, and once achieving net-zero emissions, they must remain at net-zero indefinitely. Lifetime extensions of the existing nuclear fleet, in the United States and globally, support urgent near-term emissions reduction goals. Additionally, the longevity of nuclear power technologies reduces the need for new capacity additions of all carbon-free electricity sources and supports long-term actions necessary to maintain net-zero emissions.
