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.

A thermal-hydraulic model is developed to simulate and study the dynamic behavior of bulk evaporation and condensation processes in a multiphase nuclear fuel cell. The phase-change process is driven and controlled by internal heat generation and wall heat removal under constant volume condition. The modeling involves variable gravity conditions that allow for performance analysis of the multiphase nuclear fuel for terrestrial and space applications. A complete set of governing equations for both liquid and vapor phases is developed and numerically solved. The model is used to simulate the operation of a multiphase nuclear fuel cell at zero-gravity and microgravity levels. The temperature and phase distribution, the flow field, and the evolution of the liquid-vapor interface are computed and demonstrated.
