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.

A preliminary evaluation of the use of natural convection cooling to remove waste heat from offshore nuclear power plants is presented. This approach would minimize the environmental problems of thermal and mechanical shock and excessive temperatures associated with once-through cooling. The results indicate that approximately six times the length of condensate tubing used in a conventional condenser would be needed for natural convection cooling; a more complicated steam-handling system would also be required. The concept could only be justified if a power plant is needed at a particular site where the environmental cost of the conventional system exceeded the cost of natural convection cooling.
