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.

NWMO chooses vendors for Canadian repository
Canada’s Nuclear Waste Management Organization has selected five companies it is to work with to design and plan the organization’s proposed deep geologic repository for spent nuclear fuel. As the owner of the project, the NWMO will be working with WSP Canada, Peter Kiewit Sons (Kiewit), Hatch Ltd., Thyssen Mining Construction of Canada, and Kinectrics.

Evaluation of cross-section data for various collision processes is now being made by many groups. But the results (i.e., recommended data) are often different from each other depending on who evaluates them. An evaluation (or validation) of the evaluated data is necessary. Three examples of the activity are shown here: (a) consistency check of the total scattering cross section, (b) calculation of the swarm parameters, and (c) chemical modeling. For the first two cases, a demonstration is performed with the use of the cross-section sets recommended for the electron collisions with N2 and O2 by the present author.
