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.

Uncertainty contributes to lowest uranium spot prices in 18 months
A combination of plentiful supply and uncertain demand resulted in spot pricing for uranium closing out March below $64 per pound, with dips down to about $63.50 during mid-March—the lowest futures prices in 18 months, according to tracking by analysis firm Trading Economics. Spot prices have also fallen steadily since the beginning of 2024. Meanwhile, long-term prices have held steady at about $80 per pound at the end of March, according to Canadian front-end uranium mining, milling, and conversion company Cameco.

One of the goals of fusion blanket design is to explore the blanket material design to maintain the characteristics of the internal temperature field. This is because the characteristics of the temperature field have an important influence on the effectiveness of tritium release for the blanket. In this work, the influence of material design on temperature field characteristics is studied based on a multizone structure blanket model. It mainly focuses on the positions of the breeders, the multipliers, and the structural steel, including their material proportions in the blanket interior. It was found that the temperature field in the pure breeder region Li4SiO4 is relatively independent and has little influence on the adjacent regions because its location is closer to the first wall. The first beryllium zone only affects the adjacent regions and will not repeatedly affect the remote areas. The second beryllium zone and the first mixed-pebble zone of the Li/Be zone are mainly limited to the structural materials due to the sensitivity of the temperature limitation of 550°C. This work will have very important support and reference for future fusion blanket engineering.
