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 various contaminants, namely NO2, SO2, 2-butanone [methyl-ethyl-ketone (MEK)], and NH3, on the radioiodine removal efficiency of triethyl-enediamine (TEDA)-impregnated charcoal filters has been studied, and an attempt was made to characterize and quantify the weathering process of TEDA charcoal by these contaminants. The effects of the contaminants on the CH3I removal efficiency of TEDA charcoal under dry and humid conditions are described. Based on our results, the efficiency of TEDA charcoal is degraded most by NO2 and SO2, NH3 has a negligible effect, and MEK produces a mild degradation. The degree of degradation parallels the contaminant’s ability to be chemisorbed on the TEDA impregnant. The combined effect of water vapor and a contaminant on the charcoal efficiency is different for each contaminant. Nitrogen dioxide adsorbed under dry conditions is more effective in degrading the CH3I removal efficiency of the charcoal than when adsorbed under humid conditions. On the other hand, a completely opposite result is observed for SO2. The MEK contaminant behaves similarly to SO2, but the effect of humidity was less significant than for SO2. Ammonia has no effect on the efficiency of the charcoal regardless of humidity.
