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 essential support system of the Compact Ignition Tokamak (CIT) is the Vacuum Vessel Heating/Cooling (H/C) System. The requirement for the design of the dual function H/C System is to initially provide sufficient input heat energy to raise the temperature of the vacuum vessel from a 21°C ambient temperature to the operating temperature of 340±10°C and subsequently provide sufficient heat removal capacity to limit the cooling period between plasma pulses to 1 hour. The H/C System currently proposed for the CIT vacuum vessel accomplishes both of these system objectives using a single gaseous helium system flowing through a series of ducts attached to the exterior surface of the vacuum vessel shell. The design requirements, duct arrangements, and design analyses for the preliminary H/C System design are identified.
