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.

IEA report: Challenges need to be resolved to support global nuclear energy growth
The International Energy Agency published a new report this month outlining how continued innovation, government support, and new business models can unleash nuclear power expansion worldwide.
The Path to a New Era for Nuclear Energy report “reviews the status of nuclear energy around the world and explores risks related to policies, construction, and financing.”

The extraction of 65Zn from falling liquid-metal drops of pure zinc and dilute zinc in lead alloys by fused-salt solutions of lead chloride and zinc chloride in the potassium chloride-lithium chloride eutectic has been investigated. Both chemical and isotopic exchange processes were found to be controlled by external mass transfer in the salt phase. The measured external resistances were comparable to those predicted by models based upon a rigid drop. Extraction in the pure zinc metal-lead chloride system appeared to proceed by a mechanism involving subchlorides as intermediates in the interfacial reaction.
