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.

For the specific reactors evaluated in the Reactor Safety Study (WASH-1400), quantified uncertainties in the calculated consequences and probabilities were reported, along with median estimates. The WASH-1400 evaluation of early fatalities gave these uncertainties as multiplicative factors of (, 4) on consequences and (, 5) on probabilities. Accounting for factors that were not considered, these uncertainties are better stated as multiplicative factors of (, 15) and (, 20) for consequences and probabilities, respectively. In addition to this change in uncertainty, the median values of early fatalities reported in WASH-1400 may be too high by factors of 5 for consequences and 12 for probabilities. Thus, a new upper bound is found that is less than that stated in WASH-1400.
