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.

For the first time since the Arab oil boycott of 1973, there is a strong need for new electrical capacity in the United States. For nuclear power to emerge (or reemerge) to meet this need will require a solid, economic nuclear plant product, continued safe operation of nuclear plants, the removal of institutional barriers (in particular, the cleanup of our nuclear licensing system), and public realization of the need for nuclear power. This last factor is key, but in view of the worldwide nature of our future energy problems, there are already signs that the public is perceiving the need for nuclear power.
