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.

Supreme Court rules against Texas in interim storage case
The Supreme Court voted 6–3 against Texas and a group of landowners today in a case involving the Nuclear Regulatory Commission’s licensing of a consolidated interim storage facility for spent nuclear fuel, reversing a decision by the 5th Circuit Court of Appeals to grant the state and landowners Fasken Land and Minerals (Fasken) standing to challenge the license.

A proof-of-principle device for producing isodose maps of the radiation field due to an arbitrary gamma-ray source distribution has been constructed. Borrowing methodology from medical computerized tomography imaging, radiation fields are scanned with a pair of collimated ionization chambers by a series of rotations and translations. Experimental considerations limit each scan to two carriage positions, resulting in highly distorted maps. By modeling the map distortion as the result of a linear, space invariant degrading function, an inverse filter was used to remove the distortion. Application of the inverse filter has proved fruitful, and high-quality accurate maps have been produced
