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.

Fuel behavior maps have been constructed based on an analysis developed previously by the author. The maps enable one to see at a glance fuel behavior in transient parameter space as predicted by the model. The transient conditions under which fuel responds in either a brittle or ductile manner are defined within the context of the model and displayed in the maps. The nature and disposition of grain boundary fission gas, i.e., either contained in brittle cracks or equilibrium bubbles, at the time of fuel melting are also considered. Two general types of maps are constructed, each providing a different perspective on transient parameter space.
