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 mixed carbonitride fuel irradiated to 3.9% fissions of initial metal atoms in a fast flux was examined by electron microprobe analysis. The fuel contained a large porous zone. Inclusions at the edge of the zone contained palladium and tin and were formed from the liquid phase. Within the porous region, the platinum metals occurred in the UPd3 and U(Tc0.02Ru0.78Rh0.14Pd0.06)3Cx phases, molybdenum and technetium formed inclusions of the (U,Pu)x(Mo,Tc)yCz type, and part of the rare earth elements reacted with impurity oxygen to give a sesquioxide phase. Plutonium depletion was found near the fuel center, and plutonium enrichments were measured at the outer part of the porous zone and at healed cracks in the dense fuel. Cladding carburization occurred and, at the inner cladding surface, the carbon concentration was 0.4 wt%.
