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.

Recycle of nitric acid in the UREX+ process requires removal of acetic acid. An analysis of the effects of acetic acid in each process step indicates no step will be significantly affected by the concentrations expected. Thus, acetic acid removal can be placed after the last salts are removed, just before the nitric acid is recycled. Two promising removal options have been considered, solvent extraction and distillation. Distillation requires removal of most of the water before large fractions of acetic acid are removed. The process would be energy intensive and would involve the handling of extremely concentrated nitric acid; therefore, solvent extraction appears to be more attractive.
