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.

From South Korea to Belgium: Testing a high-density research reactor fuel
The Korea Atomic Energy Research Institute has developed a high-density uranium silicide fuel designed to replace high-enriched uranium in research reactors. Recent irradiation tests appear to be successful, KAERI reports, which means the fuel could be commercialized to continue a key global nuclear nonproliferation effort—converting research reactors to run on low-enriched uranium fuel.

A new empirical scaling of the magnetic field ratio (the maximum magnetic field on the coil to the toroidal field on the center of helical windings averaged over one field period) for heliotron/torsatron systems has been proposed. This new scaling was derived from the calculation result by using a finite-volume current element code over a wide range of coil engineering parameters. The scaling is described as a product of powers of 5 dimensionless parameters that relate to the coil geometry. This scaling can reproduce the magnetic field ratio within 3% error over the wide range of design parameters. By using this new scaling, we can estimate the magnetic field in the plasma confinement region by a fast calculation with engineering design parameters only. It will facilitate the design optimization through sensitivity analysis with parameter scan over a wide range in reactor design study of heliotron/torsatron reactors.
