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.

Planar components made from glow discharge polymer (GDP) are commonly used in laser inertial fusion experiments. The thickness profile of GDP coatings on flat substrates follows a nearly Gaussian distribution with a full-width at half-maximum only 20 mm across, restricting the number of usable components with the same thickness that can be made from each substrate. A new coating method to improve the thickness uniformity and increase the usable area of GDP coatings has been simulated and involves rotating the planar substrate while it is offset from the center of the coating chamber. While the coating rate drops to about 40% at the center, the thickness variation is less than 10% out to a radius of 10 mm, increasing the usable area by a factor of over 7, thereby increasing the number of components that can be made from a single coating.
