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.

Fabrication and welding methods used to make 217-rod grid spacers for liquid-metal fast breeder reactor application have been developed. Grid straps are formed from cold-worked Type 316 stainless-steel strip material and are assembled into a hexagonalshaped honeycomb grid, using resistance welding. A support strap is then welded onto the periphery of the grid using a manual gas tungsten arc welding (GTAW) process. The grids (11) are then located and appropriately spaced inside a hexagonal duct and attached using an automatic GTAW process. Three of these subassemblies have been completed and are awaiting loading of the fuel rods. After loading, the subassemblies are to be inserted in driver positions of the Fast Flux Test Facility for the acceptance test phase.
