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 comparison is made of the experimental neutron capture background from 3 to l0 MeV of two 252Cf neutron sources, one encapsulated in stainless steel and one in Zircaloy-2. The background of the Zircaloy-2 source was significantly lower than for the stainless steel source above 6 MeV because of the absence of the high energy capture gamma peaks due to iron, chromium, and nickel. Below 5 MeV, the californium fission gamma rays are the major source of interference.
