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.

For hydrogen isotope enrichment/separation applicable to fusion fuel processing, environmental tritium safety confinement, or recovery of tritium from heavy water reactors, a hydrogen displacement adsorption process system is recommended using molecular sieve 5A as the separation material. For simulation and optimization of the process, mathematical models and a solving method are provided to calculate the breakthrough curves during the displacement adsorption, in which various parameters including pressure drop and mass transfer coefficients are allowed to be changeable. Based on the calculated results, the effects of the column size, the flow rate, and the outlet pressure on the enrichment factor, the recovery ratio and the separation ability of the column are comprehensively analyzed. The conclusions have some theoretical guiding significance for the development of hydrogen isotope separation by the displacement adsorption method.
