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 nominal 1500 STP-L PAssively Cooled, Electrically heated hydride (PACE) Bed has been developed and tested. The bed contained 12.6 kg of a La-Ni-Al alloy and used aluminum foam to improve heat transfer within the bed. Steady-state temperature measurements made at constant power showed a nonuniform bed temperature profile. Protium absorption rates were measured at pressures of 253 kPa, 413 kPa, and 680 kPa with forced convection cooling air flow rates ranging from 50 to 150 SLPM air. Absorption tests were also performed simulating the absorption of tritium and a method for estimating this rate using protium absorption data presented. Desorption rates were measured at pressures ranging from 20 kPa to 933 kPa using dual and single 400 watt electric heaters and found desorption rates were only impacted at the beginning and the end of a desorption cycle by the use of a single heater.
