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.

A review of the plutonium fuel recycle program (1955–1967) did not reveal an economically compelling alternative fuel cycle to slightly enriched uranium, plutonium recycle, or the plutonium breeder. The review included systems involving no chemical separations compared with slightly enriched uranium once through. Nor did freestanding thorium systems appear economic, although synergisms between uranium and thorium may be worth considering, including reduced-density thorium fuels with high fuel durability as an alternative to uranium load following and peaking fuel. The crossed progeny system involving 233U enrichment of uranium in light water reactors (LWRs) and conversion of the plutonium to 233U in fast reactors may offer a method of providing a high-performance denatured LWR fuel for the period beyond the availability of economic slightly enriched uranium.
