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.

Vandium alloys have been identified as one of the leading alternate cladding materials for liquid-metal-cooled fast breeder reactors for circumventing the possible limitations of austenitic stainless steels. Two of the more important aspects of this usage on which little information is available are sodium corrosion and compatibility with ceramic fuels. In this study, a series of experimental vanadium alloy compositions were found to increase in weight and in hardness after 500-h exposure to flowing sodium containing <10 ppm oxygen at ∼790°C; these changes are due to the absorption of oxygen, carbon, and nitrogen. In 1000-h tests at 800°C, some incompatibility was observed only between vanadium alloys containing iron and uranium-carbide fuel. However, these screening tests have identified three vanadium alloy compositions as worthy of further study.
