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.

The reaction of elemental iodine with liquid zinc and the reaction of Znl2 with molten chloride salt have been studied. These reactions, which occur when fission product iodine is released into a zinc-salt melt during the pyrochemical decladding of fuel elements, appear to be very rapid. The mechanism is postulated to include conversion of zinc iodide to a zinc chloride complex. The presence of zinc chloride in the melt has been verified by Raman spectroscopy. The results of laboratoryscale experiments suggest that the process for decladding LMFBR fuels in a zincsalt melt may be capable of effectively retaining fission product iodine in an easily disposable form.
