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.

Two target designs and one blanket design are discussed for the Los Alamos Accelerator Transmutation of Nuclear Waste concept. The blanket design presented includes heavy water moderator and piping systems used to contain fission products and actinide streams for transmutation to stable isotopes. A flowing liquid metal target offers the advantage of direct convection of the high heat generation and the possibility for a windowless design. Experiments will be required to test the target design and determine compatibility of the container material. Pumping and heat-transfer equipment will also require research and development. A solid target made of a combination of tungsten and lead offers the advantage of straightforward engineering design, but will require a window between the accelerator and the target.
