IAEA again raises global nuclear power projections
Noting recent momentum behind nuclear power, the International Atomic Energy Agency has revised up its projections for the expansion of nuclear power, estimating that global nuclear operational capacity will more than double by 2050—reaching 2.6 times the 2024 level—with small modular reactors expected to play a pivotal role in this high-case scenario.
IAEA director general Rafael Mariano Grossi announced the new projections, contained in the annual report Energy, Electricity, and Nuclear Power Estimates for the Period up to 2050 at the 69th IAEA General Conference in Vienna.
In the report’s high-case scenario, nuclear electrical generating capacity is projected to increase to from 377 GW at the end of 2024 to 992 GW by 2050. In a low-case scenario, capacity rises 50 percent, compared with 2024, to 561 GW. SMRs are projected to account for 24 percent of the new capacity added in the high case and for 5 percent in the low case.

Over the past 10 years, the ARIES team has been devoting a serious effort to reduce the volume of radwaste generated by fusion power plants. Recently, an initiative was launched in the U.S. and Europe to reduce the radwaste volume further by clearing the outer components from regulatory control. Before proceeding further with the development of a new strategy for the U.S. fusion waste management, it is essential to assess the implication of the clearance option on the waste generated by the U.S. advanced power plants. In this paper, we discuss the results of the analysis, the approach adopted by the ARIES team for handling the cleared components, and the U.S. market for cleared metals. Our results state that, because of the compactness of the design, none of the ARIES-AT fusion power core components has a clearance index below one at the end of the 100 year interim storage period and all components should be either recycled or disposed near surface as low-level waste. At present, the U.S. industry has zero tolerance for metals with very low radiation level, meaning the commercial market for cleared metals does not exist.
