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.

An assessment of Flibe thermo-physical properties relevant to the prompt x-rays ablation of the liquid wall is presented with emphasis given to the equilibrium vapor composition and vapor pressure. The available data sets for Flibe thermo-physical properties, which cover a very narrow range of temperature have been extended and adjusted to cover the whole range of the liquid phase and to assure consistency with the estimated critical constants. Investigation of the equilibrium vapor composition showed a contradiction with previously published results regarding the stability of the mixed dimmer LiBeF3. New results for the vapor composition and total vapor pressure of Flibe also have been presented, compared to previous results, and used to calculate the temperature-dependent latent heat of vaporization.
