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.

The shell stabilization of the tilting mode in a moving ring reactor due to the arrangement of a conductor close to the plasma is studied by numerically calculating the stabilizing torque by the eddy current induced on the conductor surface. The tilting mode instability can be successfully suppressed in the slender ring plasma with the aspect ratio of four by either an internal rod conductor or an external annular conductor. The arrangement of both rod-and annular-type conductors is required for stabilizing the tilting mode in a ring plasma with the aspect ratio of three. The effect of the mutual interaction among the eddy current is shown to be so small as to be safely neglected in calculating the eddy current induced by the tilted plasma, and the simplified treatment of the eddy current is suggested for the computation of the stabilizing torque due to the shell effect.
