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.

In the design of FED-A, quasi-steady state operation is conceived in which the plasma current is generated by the transformer coil in the burning phase and by the lower hybrid wave in the transformer-recharging phase. A parametric study was made to obtain optimum plasma and wave parameters in the recharging phase. The plasma current saturates when rf wave power increases. In order to avoid a hollow current distribution we should choose the rf power level which gives current saturation. The saturation current level is very sensitive to the width of the wave spectrum, The optimum plasma density and n11 should be determined so that the saturation current reaches to the required level and the efficiency is maximized for a given Δ n11.
