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.

The major findings of a comprehensive study of the major aspects of rock cavity construction of a large nuclear power plant are: 1. Current technology is adequate for the realization of such construction. 2. A method for estimating the probability of rock fallout and gross cavity instability is presently not available. 3. Certain design modifications and amplifications must be made to prevent dependent failures. 4. No significant reduction in the immediate radiological effects of Class 9 accidents will result unless special design measures are made for this purpose. 5. The vulnerability of the plant to certain external effects is significantly reduced. 6. The total time for the realization of such construction will be significantly longer than that for a traditionally constructed plant. 7. The extra cost will be substantial.
