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.

From South Korea to Belgium: Testing a high-density research reactor fuel
The Korea Atomic Energy Research Institute has developed a high-density uranium silicide fuel designed to replace high-enriched uranium in research reactors. Recent irradiation tests appear to be successful, KAERI reports, which means the fuel could be commercialized to continue a key global nuclear nonproliferation effort—converting research reactors to run on low-enriched uranium fuel.

The p-c-T curves of D2 and T2 absorption by Ti and Zr were measured. there are one plateau at temperature below 300 °C and two plateaus at temperature range of 500~600 °C for Ti but one plateau below 525°C and two plateaus above 525°C for Zr. The thermodynamic parameters on different phases were determined and there are obvious thermodynamic isotope effects. The lag effect was not observed for Ti but its existent for Zr. The kinetic p-t curves of absorption were investigated at different temperature ranges and then the rate constants are calculated. The results show that the rate constants increase with raising temperature for Ti but decrease for Zr. The activation energy values are (110.2±3.0), (155.7±3.2) kJ.mol-1 respectively for Ti and (-25.9±0.7), (-6.8±0.8) kJ.mol-1 for Zr. The kinetic p-t curves of desorption were investigated too and the activation energy of desorption are (42.3±1.9), (62.1±1.6) kJ.mol-1 respectively for Ti and (40.1±0.8), (57.7±1.6) kJ.mol-1 for Zr. So there are remarkable kinetic isotope effects for Ti, Zr.
