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.

Fire reported at Zaporizhzhia as Ukrainian troops advance toward Russia’s Kursk plant
Thick, black smoke pouring from one of the cooling towers at Ukraine’s Zaporizhzhia nuclear power plant over the weekend raised alarm about safety at the facility as the military conflict with Russia continues.
On-site staff from the International Atomic Energy Agency witnessed the smoke and reported hearing multiple explosions at Zaporizhzhia, which is the largest nuclear plant in Europe and one of the largest worldwide.

A new control concept, state feedback assisted classical control, is described. The concept incorporates a classical output feedback control system as an easily understood inner control loop and casts modern state feedback in the role of a demand signal augmentation to achieve the goals of an optimal control design. The new control configuration is proposed as a method to achieve transparency of control for implementation of optimal control theory for nuclear reactors and power plants. It may find acceptance for incremental modernization of existing plants because it may permit existing control loops to remain in place while new control loops are added to optionally augment demand signals to achieve an optimal control objective. This approach also leads into the design of robust and fault-tolerant control of nuclear power plants.
