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.

A calculational model is presented for the self-powered neutron detector of the type used in nuclear reactor cores. The model accounts for the neutron capture rate for beta-decaying nuclei, the electron escape probability from the emitter of the detector, and the effect of the insulator on the sensitivity of the device. Calculated unit sensitivities to thermal neutrons are presented as functions of emitter diameters and insulator thicknesses for rhodium and vanadium emitters having cylindrical geometries. The calculated values are compared with experimental values.
