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.

El Salvador: Looking to nuclear
In 2022, El Salvador’s leadership decided to expand its modest, mostly hydro- and geothermal-based electricity system, which is supported by expensive imported natural gas and diesel generation. They chose to use advanced nuclear reactors, preferably fueled by thorium-based fuels, to power their civilian efforts. The choice of thorium was made to inform the world that the reactor program was for civilian purposes only, and so they chose a fuel that was plentiful, easy to source and work with, and not a proliferation risk.

The material requirements for structural and armor applications in the future nuclear fusion reactors impose a very high barrier to be surmounted in order to fulfill the safety requirements and reliable operation of the systems. The efforts of NRG and ECN in the developing of materials by Powder / Metal Injection Molding (PIM / MIM) are very promising and show a big potential of this technique as a prospective net shape parts manufacturing method, easily scalable to industrial level. Several MIM materials were developed by the ECN and characterized at NRG within European Fusion Development Agreement (EFDA) Work Programme. Of them, two materials - pure tungsten (W) and tungsten doped with 1vol% Y2O3 are demonstrating good potential for likely future use. Therefore, further characterization efforts are needed. The MIM W-1%Y2O3 material seems to be very promising material for armor applications. Extensive thermal shock testing performed at JUDITH 1 up to 1000 cycles and up to 1273 K did not cause crack formation.Additionally, two-component mock-ups were produced using MIM technology. From the very first microstructural investigation of the join area appears that MIM technology can be used as a reliable component joining method.
