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.

This paper presents the capabilities of the International Database on Reactor Pressure Vessel (RPV) Materials (the Database) for precise and comprehensive RPV lifetime assessment, aimed at supporting the long-term operation of nuclear power plants. The Database was created in the framework of the International Atomic Energy Agency activities. Fourteen countries, including the United States, France, and Russia, supplied large amounts of surveillance results and data from national and international research programs.The recent achievements and open issues in the area of RPV radiation embrittlement assessment are considered. They concern mainly the effects resulting from long irradiation times and high neutron fluences (neutron flux influence, late blooming phases), nickel and manganese synergism, and further validation of appropriate safety concepts (the Master Curve approach).New information from ongoing surveillance and research programs has to be incorporated into the Database for the most effective RPV radiation embrittlement prediction. These additional data will greatly support the development of embrittlement correlations and embrittlement trend curves valid for long irradiation times.
