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
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

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.

Values of the gamma-ray mass attenuation coefficient for fly-ash glasses in the system: xBi2O3-0.2B2O3-yFly Ash and xPbO-0.2B2O3-yFly Ash (x = 0.70, 0.65, 0.60, 0.55, 0.50, 0.45, 0.40 and y = 0.10, 0.15, 0.20, 0.25, 0.30, 0.35, 0.40) have been determined experimentally at 81-, 356-, 511-, 662-, 1173-, and 1332-keV photon energies using a narrow-beam transmission method. These coefficients of glasses are then used to determine their interaction cross sections, the photon mean free path, effective atomic numbers, and the electron densities. Results have indicated that these fly-ash glasses have potential applications in low-energy gamma-ray shielding.
