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.

Why should safeguards by design be a global effort?
Jeremy Whitlock
I can’t think of a more exciting time to be working in nuclear, with the diversity of advanced reactor development and increasing global support for nuclear in sustainable energy planning. But we can’t lose sight of the need to plan for efficient international safeguards at the same time.
Global nuclear deployment has been underpinned since 1970 by the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), making it a key customer requirement for governments to demonstrate unequivocally that the technology is not being misused for weapons development.
The International Atomic Energy Agency (IAEA) has helped verify this commitment for more than 50 years, but it has never safeguarded many of the advanced reactors (and related fuel cycle processes) being developed today.

A fusion nuclear science facility (FNSF) is a necessary complement to ITER, especially in the area of material and component testing needed for DEMO design development. FNSF-AT, which takes advantage of advanced tokamak (AT) physics, should have neutron wall loading of 1-2 MW/m2 , continuous operation for periods of up to 2 weeks, a duty factor goal of 0.3 per year, and an accumulated fluence of 3-6 MW-yr/m2 ([approximately]30-60 dpa) in 10 years to enable the qualification of structural, blanket, and functional materials, components, and corresponding ancillary equipment necessary for the design and licensing of a DEMO. Base blankets with a ferritic steel structure and selected tritium blanket materials will be tested and used for the demonstration of tritium sufficiency. Additional test ports at the outboard midplane will be reserved for test blankets with advanced designs or exotic materials and electricity production for integrated high-fluence testing in a DT fusion spectrum. FNSF-AT will be designed using conservative implementations of all elements of AT physics to produce 150-300 MW of fusion power with modest energy gain (Q < 7) in a modest-sized normal conducting coil device. It will demonstrate and help to select the DEMO plasma-facing, structural, tritium-breeding, and functional materials and ancillary equipment including diagnostics. It will also demonstrate the necessary tritium fuel cycle, design and cooling of the first wall chamber, and divertor components. It will contribute to the knowledge on material qualification, licensing, operational safety, and remote maintenance necessary for DEMO design.
