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.

The behavior of dynamic desorption of He, H2, and CH4 from a cryosorption pump is experimentally investigated using a simplified technique to roughly purify unburned D-T fuel exhausted from a fusion reactor. As a fundamental study to dynamically separate the unburned fuel and impurities, the discharge rates of H2 (as a representative of D2 and T2), He, and CH4 (as major impurities) are determined as a function of time or temperature, when the cryosorption pump is regenerated from [approximately]10 K to the room temperature of 285 to 300 K according to the experimental date. It is found that H2 is adsorbed and desorbed on active charcoal independent of the adsorption sites of He and CH4, which are evacuated simultaneously. The present result leads to a simplified method for roughly separating unburned fuel from impurities in fusion reactors by controlling the desorption temperature.
