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.

Advanced fuel designs have been developed with the aim of improving fuel cycle efficiency. With this idea, moderator distribution in boiling water reactor fuel assemblies has been improved. The current work analyzes two 9×9 fuel assemblies with different inner channel designs. The first design corresponds to an actual assembly, whereas the second is proposed with the aim of making comparisons between their performances. The former design is an internal parallelepipedal water channel, and the latter is an internal cylindrical water channel whose diameter is equal to one side of the first. It is observed that the former assembly has a better burnup. Reloads for Laguna Verde Nuclear Power Plant are simulated for each design. Better operational limits are obtained by using the latter assembly. The increase in the amount of water yields a more uniform burnup, although as shown in this study, this fact does not necessarily improve the plant operational limits.
