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 1000-MW(electric) fusion power reactor concept based on electrochemically induced D-Dn, D-Dp, and deuterium-tritium reactions is presented. A D- He reaction is not possible because He is not absorbed in the electrode. The concept of a tube-type fuel cell is presented. The inner surface of the tube is laminated with palladium. The cell provides a large cathode surface and efficient heat transport to the water coolant. The fuel assemblies and bundles of fuel tubes are installed in the pressure vessel. The reactor system is very similar to a pressurized water reactor, though the reactor internals are much simplified due to the elimination of fission fuel pellets and control rods. The spatial power distribution of the reactor core is very flat compared with that of fission reactors.
