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.

Simulated high-level liquid waste was irradiated by 60Co gamma radiation, and changes in the gas-phase concentrations of the products H2, O2, and NOx that accumulated in the absence of sweeping air were measured. The H2 concentration reached a steady-state value of much less than 4% in line with the value predicted from the previously derived mathematical expression. The simulated dissolver solution was also irradiated, and another steady-state H2 concentration of much less than 4% was obtained in accordance with the corresponding predicted value. These experimental results lend strong support for the applicability of a mathematical expression in predicting the H2 concentration in a tank in the case of a sweeping-air function loss.
