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 fabrication of three multilayer Omega-scale capsule designs with combinations of materials such as beryllium, silicon, tungsten, and copper were evaluated as part of the fabrication and delivery process. These opaque capsule designs presented characterization challenges in that nominal optical characterization techniques for Omega-scale designs were not sufficient to fully characterize the capsules. Alternate techniques such as X-ray fluorescence, radiography, scanning electron microscopy, and spectroscopy needed to be utilized in order to characterize these capsule designs. Additionally, the permeability of each material varies; therefore, each capsule design required a different approach to fill the capsule for the experiment. Three techniques were used to deliver gas-filled capsules to the experimental teams: (a) filling through the drill hole, sealing with glue under pressure, and minimizing the glue mass using laser ablation; (b) attaching a capsule fill tube assembly into the drill hole; and (c) gas permeation through the wall. The issues encountered with these techniques and their solutions are presented.
