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.

Stacked couples of silicon carbide and Zircaloy-4 discs were annealed for 1 h in nominal inert atmosphere (6N Ar) at temperatures of 1200, 1400, 1500, 1550, 1575 and 1600°C. Strong interactions between silicon carbide and Zircaloy-4 occurred at temperatures of 1500°C and above. The width of the influenced zone exceeds 1 mm at 1550°C. A pronounced layer structure was found consisting of Zr-Si intermetallic compounds with different stoichiometry, the Zr-Sn intermetallic phase Zr2Sn and sub-stoichiometric ZrC1-x. The six different layers formed at temperatures of 1500°C and above contain these phases in diverse concentrations. At temperatures of 1575 and 1600°C, the discs welded together. This paper gives a detailed description of the results of the post-annealing examinations and an analysis of the interaction between the two materials.
