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.

Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.

Hydrodynamics growth experiments involve rippled ablator samples (CHx, Ge:CH, or Si:CH). The rippled surface features a microscale mathematical shape (sinusoidal functions are widely used). Nevertheless, experiments have progressed with time, and samples evolved gradually from two-dimensional (planar samples) to three-dimensional geometries (capsules).
This paper presents various processes that have been developed to fulfill such specifications. Various technologies, based on laser means (excimer laser, Ti:sapphire laser) or mechanical ultraprecision means, have been successfully applied to ripples machining (planar samples or capsules).
The main results are discussed showing the ability and accuracy of each technology as well as their main limitations. We focus especially on our latest results (i.e., rippled or grooved capsules).
