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 design and characterization of a high-power microwave launcher have been discussed. The launchers have been designed for electron cyclotron resonance heating of the plasma in the Steady-State Superconducting Tokamak (SST-1). High-power microwave beam launchers mainly consist of a focusing mirror and a plane mirror combination to focus the beam at a specified location. Two microwave beam launchers are fabricated to launch the waves from the low magnetic field side (radial port) as well as from the high magnetic field side (top port). The frequency of operation is 82.6 GHz, and the power is 200 kW/continuous wave. A gyrotron capable of delivering 200 kW power at 82.6 GHz is under fabrication at M/s. Gycom. The mirrors of the launchers are based on quasi-optical Gaussian beam theory. The mirrors provide cooling for long-pulse (1000-s) operation. Low-power microwave characterization is done to check the performance of the launchers. A low-power microwave beam incident on the focusing mirror of the launcher and focusing action is analyzed at the output of the launcher.
