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.

College students help develop waste-measuring device at Hanford
A partnership between Washington River Protection Solutions (WRPS) and Washington State University has resulted in the development of a device to measure radioactive and chemical tank waste at the Hanford Site. WRPS is the contractor at Hanford for the Department of Energy’s Office of Environmental Management.

A new model is developed for an electron-cyclotron-resonance-heated plasma confinement in an open mirror magnetic trap. The model is based on the simultaneous study of noncollisional kinetics of electrons and gas dynamics of ions. At the trap center, the electron distribution function is approximated by bi-Maxwell distribution (with effective temperatures T⊥ and T‖ – mean energies of the transverse and longitudinal to the magnetic field motion). Within the model framework the ion confinement time as well as the axial distribution of the ambipolar potential and plasma density has been investigated both numerically and analytically. The confinement time and potential profile are very much dependent on the electron distribution anisotropy and, in strongly anisotropic case, on the ion temperature. The ambipolar potential changes qualitatively while the ratio T⊥/T‖ exceeds a certain threshold value. Below the threshold, the potential falls off monotonously along the trap axis outwards from the trap center. After the threshold is exceeded, there appears a potential peak between the center and the plug. This potential peak retards ion escape through the plug and provides quite different confinement of ions with different charges in an ECR ion source.
