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 analysis is presented of the radioactive wastes from the International Thermonuclear Experimental Reactor (ITER) and how those wastes would fit into the regulatory environments of four potential host nations: France, Germany, Japan, and the United States. The reactor described in the ITER Draft Interim Design Report is used as the basis for the radioactive inventory assessments that are carried out using ONEDANT for the neutron transport calculations and ACAB for the activation calculations. The radioactive material produced by operation of the reactor is rated according to the protocols for waste management in each nation and at specific disposal sites currently operating in those nations. Results of the assessments vary drastically between disposal sites - even between near-surface-burial sites within the U.S. Department of Energy. One disposal site (Westinghouse Hanford Company) could accept all of ITER's wastes after a storage and cooling period (all wastes are assessed at 30 yr after shutdown). Other sites (the Savannah River and the Nevada Test Sites) could not accept any components within the toroidal field coils, similar to the restrictions in Germany. Blanket modules would be excluded from near-surface burial in France and Japan, but other components may qualify.
