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.

Candidate processes for commercial high-level waste solidification are radiant-heat spray calcination, rotary-kiln calcination, and fluidized-bed calcination. Radiant-heat spray and rotary-kiln calcination have been studied only on a pilot-plant scale; plant-scale fluidizeded solidification of U.S. Atomic Energy Commission high-level wastes has been operating for more than 10 years. Cold pilotlant studies using the radiant-heat spray and fluidized-bed processes are currently underway on simulated commercial wastes. Encouraging results to date show that the existing fluid-bed solidification process pioneered at the Idaho Chemical Processing Plant is applicable to commercial waste processing with some process and equipment modifications. These modifications are mainly in areas connected with uncontrolled heating during postulated collapse of the fluidized bed, off-gas cleanup, and equipment design for compatibility with total remote maintenance.
