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.

NuScale Energy Exploration Center opens at George Mason University
NuScale Power Corporation has opened another Energy Exploration (E2) Center—this one at George Mason University in Arlington, Va. Just last month, a NuScale E2 Center opened at South Carolina State University in Orangeburg, S.C. The newest E2 at George Mason is the company’s 11th center.

In continuation of 20 yr of experience with high-temperature gas-cooled reactor graphite fuel element fabrication (molded fuel spheres and monolithic block fuel elements), NUKEM introduced a new graphite-based material with an inorganic binder produced by molding. A mixture of nickel and sulfur is used as the inorganic binder for natural graphite powder. The fabrication is facilitated by the low temperature of 500°C in generating a chemically and thermally stable nickel sulfide. The newly developed material is suitable as a matrix for the fixation of high-active waste and as a corrosion-resistant layer of the steel supporting tube for final disposal of spent fuel elements. The material of natural graphite/nickel sulfide is distinguished by high density, high corrosion resistance, a low leaching rate, good thermal conductivity, an appropriate coefficient of thermal expansion, and high thermal stability due to the high melting point of nickel sulfide ( 790°C). Currently, a pilot plant for fabrication of containers for spent fuel elements is being erected. Additionally, development work is in progress to obtain basic design data for a high-level waste fixation facility.
