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
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

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.

Radio-frequency waves can penetrate thermonuclear plasmas, depositing momentum and energy with great selectivity: in select resonant ions or electrons, in select resonant regions, and with select momentum. When these waves are injected asymmetrically with respect to the toroidal direction in tokamaks, they can drive a toroidal electric current. The advantage of driving this current by waves is that a tokamak reactor might then be operated in the steady state. This lecture will review the elementary processes of wave-particle interactions in plasma that underlie the current drive effect.
