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.

The effect of outdoor weathering of impregnated charcoal beds used for the trapping and retention of methyl 127I vapor was studied under various dynamic flow conditions. The data showed that the first or inlet segment of the bed suffered the greatest degradation in its role as a guard layer for the remaining segments of the bed. Test results were analyzed in terms of the parameters of adsorption capacity and adsorption and desorption rate constants. As was expected, the desorption rate constant was much smaller than the adsorption rate constant. The dimensionless ratio of the adsorption to the desorption rate constant can be considered as a retentivity index for any particular charcoal.
