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.

A method is developed to evaluate the maximum allowable temperature and dry storage time of spent fuel under postulated increasing temperature accident conditions, based on creep strain predicted by an empirical creep equation and the creep strain criterion. The creep equation uses the actual stress as the applied stress due to changes in internal rod pressure, fuel rod shape, and volume ratio of free to pellet fuel. It is shown that this method is more realistic and practical than one based on the life fraction rule and the creep rupture criterion. A sensitivity study of the method indicates that the maximum allowable temperature depends on the temperature increase rate, but not the initial normal storage temperature; the allowable storage time, however, depends on both.
