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.

Integral tests have been made for 27 nuclear activation cross sections required for neutron dosimetry at accelerator-based irradiation facilities. Thirteen materials were irradiated in a well-defined geometry using neutrons produced by stopping 14- to 16-MeV deuterons in a thick beryllium target. The neutron spectrum was measured by time-of-flight spectrometry. Comparison of the activation integrals with the differential neutron spectrum provided an assessment of the nuclear data. A small fission chamber was used to monitor the irradiation, map flux gradients, and study attenuation and scattering effects. Comparison of the fission rates to fission product activations in the foil materials was also used to measure cumulative fission yields for 235U and 238U.
