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.

Industry experts discuss nuclear’s role in powering data centers, meeting climate goals
As a primer to the American Nuclear Society Winter Conference and Expo, ANS Executive Director/Chief Executive Craig Piercy hosted a panel discussion titled “The State of Nuclear,” sponsored by the ANS Trustees of Nuclear. The October 29 discussion, the first in a two-part series, featured five thought leaders from the nuclear community as they reviewed the current state of nuclear power. The second panel took place during the ANS Winter Conference in Orlando, Fla., on November 18.

Directional detection of fast neutrons emitted by special nuclear materials can be performed with a time projection chamber. This device permits particle identification and full three-dimensional reconstruction of charged-particle tracks produced by interaction of fast neutrons in the chamber active volume. Single-recoil-proton reconstruction allows rapid pointing, while the reconstruction of two recoil protons produced by a single incident neutron event can enable a measurement with very high angular resolution. Kinematic reconstruction algorithms for both of these cases are presented and their performance assessed using data generated by a simple Monte Carlo simulation and experimental data where those exist. The simulation data are also used to estimate the relative efficiency of both neutron imaging modalities as a function of the volume and pressure of the time projection chamber.
