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 21S metastable helium atomic beam injector was studied for a beam probe of electric field diagnoses, which is applicable to high electric potential region in Inertial Electrostatic Confinement Fusion (IECF) plasmas where a solid probe can hardly be utilized. With deuterium background gas (~0.1Pa) which is the minimum operation pressure of the IECF devices, the beam density was found to decrease ten times lower than beam density without background gas because of collisional effect. Also, plasma parameters in a-magnetron-discharge-based exciter were evaluated by means of Langmuir probe and emission spectroscopy. These results strongly imply a high excitation rate of ~10-4 into 21S metastable state.
