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.

Experiments on deuterium permeation through S.S.316L with FeAl/Al2O3 composite coating have been performed in the temperature range 277-600°C at driving pressures 1-50kPa. As comparison, the tests for samples with natural oxidation film and Ni-plating have also been performed. The apparent deuterium permeability in the sample with FeAl/Al2O3 coating is an order of magnitude lower than that with natural oxide layer, and is at least three orders of magnitude lower than that in the non-oxidized material by inference. The apparent activation energy of deuterium permeation is 76.6kJ/mol for the coated sample and 61.3kJ/mol for the sample with natural oxidation film. The exponential dependences of steady flux for the samples on the pressure are 0.89 for FeAl/Al2O3 coating, 0.65 for natural oxidation film, and 0.55 for Ni-plating, that reflects different permeation mechanism for various surfaces. In addition, the trapping effect of defects on hydrogen isotope was inferred according to the different characteristic of permeation flux curves for various samples.
