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.

Fusion Energy Week begins today
Fusion is riding a surge of attention that began in December 2022 when researchers at Lawrence Livermore National Laboratory’s National Ignition Facility achieved fusion ignition. The organizers of Fusion Energy Week—a group called the U.S. Fusion Outreach Team—on the other hand, trace fusion development back 100 years to the doctoral research of Cecilia Payne-Gaposchkin, who discovered that stars, including our Sun, are mostly made of hydrogen and helium, which in turn led to the understanding that those elements are the “fuel” of potential fusion energy systems on Earth. In recognition of Payne-Gaposchkin’s birthday—May 10—the U.S. Fusion Outreach Team plans to hold a “grassroots celebration of fusion energy” May 6–10, 2024, and annually during the second week of May.

The High-Temperature Engineering Test Reactor (HTTR) is a 30-MW(thermal) helium gas-cooled reactor that uses a prismatic block. The core bottom structure (CBS) of the HTTR consists of an arrangement of graphite components, and it supports the core elements within the reactor vessel. Vibration tests are performed with two scale models to clarify the seismic response of the CBS. The vibration characteristics of the CBS are clarified quantitatively, and the structural integrity of the graphite components is confirmed.
