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.

Taking shape: Fusion energy ecosystems built with public-private partnerships
It’s possible to describe fusion in simple terms: heat and squeeze small atoms to get abundant clean energy. But there’s nothing simple about getting fusion ready for the grid.
Private developers, national lab and university researchers, suppliers, and end users working toward that goal are developing a range of complex technologies to reach fusion temperatures and pressures, confounded by science and technology gaps linked to plasma behavior; materials, diagnostics, and electronics for extreme environments; fuel cycle sustainability; and economics.

Publications considered a project of aneutronic reactor (the P11B reaction) based on the asymmetric centrifugal trap (ACT), the energy of protons and alpha particles leaving the reactor subjected to direct transformation to electrical energy.These works considered a project of such a reactor under some simplifying assumptions. The most significant of them is that of the scheme of the intermediate Be nucleus decay into 2 alpha particles through the ground state, which determined the energy spectrum of these particles. However, there are two channels of decay of this nucleus in this reaction, i.e., through the ground state of Be and through its excited state, see Fig. 1. It can be seen from calculation in that the probability that the reaction goes through the excited state is two orders higher than the ground state variant.It significantly changes the shape of the energy spectrum of alpha particles and makes it necessary to somehow change the scheme of their energy recovery in this project, the scheme of realization of the main process (the P11B reaction) remaining unchanged.
