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.

An inner mirror throat of the plug/barrier cell is one of the noticeable locations in the tandem mirror GAMMA10, because the location is the most suitable for a measurement of the ions bounced by the plug potential, which are essential for the tandem mirror confinement. A lithium beam probe was designed as a main part of the diagnostic system to measure the radial profiles of the electron and neutral particle density at the inner mirror throat. A neutral lithium beam is injected into the plasma and the light emitted from the beam is detected. We estimated the upper limit of the plasma density measurable by the lithium beam probe and discussed validity of the reconstruction for various types of radial profiles. We adopted, at first, a Gaussian type of radial profile of the density with the radius of 2.5 cm for the estimation of the upper limit of the density. It was found that the profile reconstruction was carried out well up to the peak density of 5 × 1013 cm-3, and also well even in the non-axisymmetric radial profile. This method is quite appropriate for the measurement of the density profile at the inner mirror throat.
