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.
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.

U.S. reactor technologies to be featured at IAEA conference
A virtual side event at the 64th General Conference of the International Atomic Energy Agency will spotlight U.S. reactor technologies. The free event, US Reactor Technologies: Flexible Energy Security for Real-World Challenges, will be held this Thursday, September 24, from 9:00 a.m. to 10:30 a.m. (EDT).
The event will highlight the capabilities of small modular reactors and other innovative reactors for addressing countries’ current needs. It will also examine anticipated challenges in the future, as well as underscore the need to act now.
The event is sponsored by the U.S. Department of Energy’s Office of Nuclear Energy. Advanced registration is required.

Materials have a primary purpose in the design of space vehicles, such as fuels, walls, racks, windows, etc. Additionally, each will also effect space radiation protection. The shielding capabilities of 39 materials and nine layering configurations are evaluated for deep space travel in terms of whole-body effective dose equivalent (ED). Polymer and composite materials are also evaluated in terms of . It is clear that a “magic” material or layering configuration is not possible; however, polymers and composites should be used instead of metals if they can serve their primary purpose. Polyethylene is shown to be the best feasible material from this material sample. Thermal neutron absorbers 6Li and 10B do not have a significant effect on ED as homogeneous shields or in layering configurations. Alloying of materials such as aluminum for strengthening purposes does not increase ED. Tanking liquid hydrogen within aluminum does significantly reduce ED when compared to aluminum. Ultimately, a space vehicle is a system of systems and radiation protection must be one of them.
