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.

Framatome signs contracts with Sizewell C
French nuclear developer Framatome is slated to deliver key equipment for Sizewell C Ltd.’s two large reactors planned for the United Kingdom’s Suffolk coast.
The agreement, reportedly worth multiple billions of euros, was announced this week and will involve Framatome from the design phase until commissioning. The company also agreed to a long-term fuel supply deal. Framatome is 80.5 percent owned by France’s EDF and 19.5 percent owned by Mitsubishi Heavy Industries.

Just recently, the ARIES team completed the detailed design of ARIES-ACT-1 with aggressive physics and advanced SiC technology. The ability of the SiC/LiPb blanket to provide tritium self-sufficiency was among the important issues investigated in detail. To pinpoint the design elements that degrade the breeding the most, we developed a novel stepwise approach that involves building the CAD model from scratch, and, in multiple steps, adding the internals/externals of the blanket. At each step, the impact on the tritium breeding ratio (TBR) was recorded to identify the more damaging/enhancing conditions or changes to the tritium breeding. The TBR approaches 1.8 for an ideal system, and then degrades to 1.05 for the ARIES-ACT-1 reference design. This paper sheds light on several breeding-related issues that puzzled the fusion community for decades and gives insight about the impact on TBR of the individual blanket internals as well as other essential parts of the tokamak.
