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.

Pacific Fusion predicts “1,000-fold leap” in performance, net facility gain by 2030
Inertial fusion energy (IFE) developer Pacific Fusion, based in Fremont, Calif., announced this morning that it is on target to achieve net facility gain—more fusion energy out than all energy stored in the system—with a demonstration system by 2030, and backs the claim with a technical paper published yesterday on arXiv: “Affordable, manageable, practical, and scalable (AMPS) high-yield and high-gain inertial fusion.”

Economic, environmental, and political pressures are consistent powers of change. Over the past several decades, nuclear has remained the principle force for reliable, cost-effective electricity and clean, carbon-free energy. However, it is no secret that sufficient change in the energy market has accumulated, leading to a tipping point for nuclear power within the United States. As in all other markets, nuclear must adapt to survive and remain a critical cog in America's energy portfolio. Integrated energy systems, expanding the nuclear energy market beyond electricity to thermal heat applications and flexible operation, may be the key to nuclear's existence in the 21st century and beyond. In this session, various panelists will highlight the ongoing research for development and deployment of such systems and provide examples from use cases that are currently being analyzed for further discussion on technical merits and foreseen challenges.
