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
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

Commercial nuclear innovation "new space" age
In early 2006, a start-up company launched a small rocket from a tiny island in the Pacific. It exploded, showering the island with debris. A year later, a second launch attempt sent a rocket to space but failed to make orbit, burning up in the atmosphere. Another year brought a third attempt—and a third failure. The following month, in September 2008, the company used the last of its funds to launch a fourth rocket. It reached orbit, making history as the first privately funded liquid-fueled rocket to do so.

A dual coolant Pb-17Li (DCLL) blanket concept has been selected as reference design for the ARIES-CS compact stellarator power plant study. This configuration is characterized by helium cooled first wall and ferritic steel structures, and a self-cooled breeding zone. Flow channel inserts (FCIs) made of silicon carbide (SiC) composite are placed in the PbLi channels, serving both as thermal and electrical insulator. The goal is to optimize the Pb-17Li inlet and outlet temperatures for high power cycle efficiency while accommodating the material temperature limits, providing reasonable flow distribution and maintaining an acceptable pressure drop.A numerical study of magnetohydrodynamic (MHD) flows in the poloidal channels that distribute the liquid metal in the breeder units has been carried out to assess the performance of such a concept with regard to the above mentioned goals and constraints. The analysis considers the electrical coupling between adjacent poloidal ducts and the influence of various parameters such as the electric conductivity of the SiC insert and the orientation of the magnetic field.
