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.

Lithium metatitanate (Li2TiO3) is a candidate tritium breeding material for fusion reactor blankets. In an actual blanket the pebbles are geometrically confined in a containing structure subjected to displacement and stress constraints under operating conditions. For an accurate description of pebble behavior during operations, existing data of pebble deformation under compressive loads is inadequate. In this study a uniaxial compression experimental apparatus was built to investigate time dependent creep on a single pebble as a function of applied force and temperature relevant to blanket conditions. Experimental results shows that at a temperature range of 700-800 °C, the crush load of Li2TiO3 pebbles is reduced by about half of its room temperature crush load. The experimental results allow for the establishment of a pebble creep failure map as a function of force and temperature, which provides guidance to the blanket designs. The study also introduces an FEA model based on experimental deformation data to obtain the constitutive equation needed for Discrete Element Model simulation of the pebble bed.
