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 new Inertial Electrostatic Confinement (IEC) fusion device has been manufactured as a compact neutron source. This device consists of double jacket chambers to provide sufficient water cooling, having the diameters of inner and outer chambers of, respectively, 20 cm and 30 cm. The effective water-cooling enabled the IEC device to operate at high cathode current of more than 80 mA. A target neutron yield of 1 × 107 has been achieved for cathode voltage of 80 kV and (cathode) current of 80 mA. The water jacket of a 5 cm width was designed as well to assure the sufficient reflection of 2.45 MeV D-D neutrons downward, where a thinner 1 cm thick water jacket is installed at the bottom. This non-uniformity of water jacket thickness resulted in increased neutron flux downward.
