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.

Waste from resource extraction industries contains uranium and thorium decay chain radionuclides. One important radiological impact of these wastes is the release of radon into the atmosphere. Therefore, the prediction/evaluation of radon flux and the effectiveness of different covers are the major elements in radiation protection, long-term safety aspects, and the modeling of radon release into the environment for a final assessment of radiological impacts and required remediation actions. A measurement system has been designed based on the transient-diffusion method to evaluate radon exhalation by the short-time accumulation technique. The validity of the laboratory model to quickly estimate the radon release from soils, the diffusion coefficient, and the effect of covers was investigated. From the results obtained from the experimental model, it was observed that after a 0.5-m(1-m) cover layer, the radon flux reduction factor increases from 1.3(2.1) for sand to about 2(3) for clay. The results show that the effectiveness of the cover layer studied is 3, which is similar to theoretical and experimental results in uranium tailings ponds.
