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.

The susceptibility of Ontario Hydro’s steam generators to the denting corrosion phenomenon is investigated as one aspect of an ongoing research program designed with the objective to specify limiting steam generator water contaminant concentrations for reliable unit operation. Isothermal test capsules and static autoclave experiments with cylindrical shrouds and heated crevice assemblies were used to assess the influence of sludge and heat flux on the concentration of solutes in crevice or low flow regions with lake waters as the test environments at 288°C. Rapid corrosion of carbon steel was observed. Sludge packed crevices enhance the concentration phenomenon, which is also very dependent on heat flux.
