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.

The National Ignition Tuning Campaign involves a dozen capsule designs. These capsule designs vary in diameters, layer thicknesses, and germanium doping levels, examining implosion velocity, entropy, hot-spot shape, mix, and uncertainty. Overall yield of these tuning capsules involves meeting all individual specifications, including layer thicknesses, doping levels, outer surface smoothness, and inner diameter. The yield of scaled tuning capsules with acceptable inner diameters is greatly affected by the available mandrel diameter and its size distribution.Surface low mode and isolated defect specifications have been tightened. The new specification allows smaller and fewer isolated defects. The surface specification is quantified in terms of low mode factors, peak velocity root-mean-square (PVRMS), mix mass, and ignition threshold function (ITF). The total mix mass from all isolated defects should be <40 ng, and the PVRMS value should be <10 m. While most current capsules meet the PVRMS requirement, only some tuning capsules have a mix mass <40 ng. The majority of capsules have a mix mass >40 ng, caused by a few larger domes. The ITF is related to isolated defects and capsule power spectra. Some capsules exceed the ITF specification value of 1.3.
