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.

Monoenergetic neutron bursts in heavy moderators are being examined for application to the nondestructive assay of fissile material in fuel samples. The goal of these assays is the determination of fissile isotope content, generally in the presence of other fissile or fertile isotopes. The technique utilizes the relationship between neutron energy and the slowing down time, or time elapsed after the burst in the heavy moderator. The slowing down time spectrometer, a lead cube into which 14-Me V neutrons are pulsed, is used to determine the fissile isotope content. Differences in fission cross sections at specific energies are used to discriminate between fissile isotopes in the same sample.
