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.

Nuclear new build procurement considerations
It may seem counterintuitive, but the best time to enhance the ability to support operations and maintenance for a new plant is before construction starts. This is one of many lessons learned by the currently operating nuclear fleet. As construction and startup of many nuclear facilities was completed, it quickly became evident that the ability to efficiently support operations and maintenance was limited. Most of the information necessary to establish and manage procurement of spare and replacement items, maintenance, and configuration of the facilities was unavailable and had to be gathered on a case-by-case, “on-demand” basis. Absence of necessary information and the associated challenges resulted in the need for staff augmentation and multiyear-long projects to develop equipment bills of material and maintenance programs and to perform technical evaluations for the huge quantities of spare and replacement items being requested.

Accelerators have been integral to subsurface probing for decades. Tools with deuterium-tritium (D-T) generators and scintillators utilizing gamma rays from thermal neutron capture, inelastic scattering, and activation are routine in cased-hole logging tools for reservoir and well monitoring to locate and quantify remaining hydrocarbons prior to initiating secondary or tertiary production. X-ray and neutron generators field-tested to, respectively, replace 137Cs and americium-beryllium (Am-Be) source tools that measure two bulk parameters, formation density and neutron porosity critical for initial characterization of formations, have yielded mixed results. D-T generator-based spectroscopy tools with advanced scintillators that can record both inelastic and capture n-gamma spectra, faster and with much better energy resolution, to provide a more complete mineralogy appear poised to replace Am-Be–based mineralogy tools. In view of their ability to measure both bulk and spectral parameters, accelerator-based nuclear methods appear attractive to extract additional geological information needed to transition to a low-carbon energy future.
The paper discusses the current state of application of accelerator-based subsurface probing techniques, notes their potential for nonpetroleum applications, and concludes by briefly exploring technology advances that could significantly advance the state of the art.
