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.

Propagation behavior of 3–4 kHz electron density fluctuation in the core and edge regions was investigated in the GAMMA 10 tandem mirror device. Frequency analysis was employed for high spatiotemporal-resolution fluctuations measured by gold neutral beam probe (GNBP) in the central cell and Langmuir probes in the end region. We found same-frequency periodic fluctuations in both signals and applied the correlation analysis technique. By considering the geometry of the measurement system, propagation speeds of the periodic fluctuation along and across the magnetic field lines were estimated.
