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.

An iterative correction method based on gamma attenuation in matrix material and self-absorption in plutonium has been developed for the nondestructive gamma assay of plutonium waste. In the process, the equivalent atomic number of the matrix material and the lump radius of plutonium are estimated. These estimations can be used for the detection against possible covert diversion of plutonium. Both homogeneous and heterogeneous samples were tested and consistent results were obtained. Specially shielded lump plutonium samples canned in the waste drums were tested and the contents of those samples were adequately disclosed.
