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.

This paper discusses an ongoing effort to evaluate the use of Glow Discharge Optical Emission Spectroscopy (GDOES) for after-exposure, target surface characterization in a plasma-materials interactions (PMI) facility, without need to remove the sample from the facility's vacuum chamber and/or to expose the sample's surface to air. The effort includes testing of a compact, inductively-coupled plasma (ICP) source, which would eventually become part of an integrated, movable GDOES sub-chamber, including plasma source, gas-feed and pumping capability, configured to function inside the main vacuum chamber. The present, conceptual design for implementation on PSI-2 shows promise in meeting these challenges and is presented here.
