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.

A new type of experimental apparatus is developed to induce continuous diffusion of deuterium, in which an electrochemical cell for calorimetry and a vacuum chamber for nuclear measurement are divided by a Pd sheet. Continuous X rays ranging from 10 to 100 keV and neutron and excess heat production are observed using the apparatus. Titanium atoms are detected on the surface where deuterium atoms pass through on Pd cathodes after electrolysis. Quantitative discussion shows that the detected Ti atoms cannot be explained by contamination. An electron-induced nuclear reaction (EINR) model for explaining the obtained experimental results is introduced. Experimental support of the EINR model is demonstrated by using multilayer cathodes, in which a layer containing Ca is placed at the near surface of Pd, based on the EINR model.
