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.

As a part of ARIES-ACT research, we have been performing a detailed re-examination of requirements and design of vacuum vessels for fusion power plants. This paper discusses structural analysis performed in support of this examination. We have performed parametric 3-dimensional finite element analyses of ARIES-ACT-type vacuum vessels. The vacuum vessel structure is subjected to different types of loads such as atmospheric pressure, weight of the vessel itself and off-normal loads such as over-pressurization due to a leak in fusion core components, electromagnetic forces from disruptions, etc. Ribbed structure is considered in order to minimize the thickness of the vacuum vessel as well as to cool the system. We will discuss our results including structural response to various loads and trade-offs among structural design choices.
