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 first wall of the National Ignition Facility (NIF) target chamber will be a source of contamination for the final optics assemblies (FOA) debris shields. The expected x-ray fluence on NIF can be as high as 2 J/cm2 for 20 MJ target yields. This is sufficiently intense to mobilize first wall material and contaminants that have been deposited on the first wall. Since 90% of the aluminum target chamber surface area will consist of first wall panels, it is critical to choose a material that is not easily mobilized by target x-ray emissions. Additionally, it would be advantageous to have a first wall design that provides a sink for mobilized material in the target chamber. With these issues at hand, a louver design has been proposed as the configuration of the NIF first wall. Experiments simulating the proposed louver geometry were fielded on Nova at x-ray fluence levels comparable to those expected on NIF. The results of these experiments were applied to the understanding of NIF contamination issues and used as a benchmark for the TSUNAMI code. Numerical studies were performed to measure the collection efficiency of the louver design where several parameters including louver length, distance between louvers, and x-ray fluence were varied.
