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.

This paper examines the main features of the gas purification process from tritiated water vapor at any relative humidity using water phase isotope exchange. The experimentally evaluated overall mass transfer coefficient (KOG) for structured CY black packing manufactured by SULZER Chemtech (Switzerland) was used as the main performance parameter of the method. The obtained KOG dependencies on various process parameters (temperature, water and gas flows, and their ratio) demonstrate that column operation in adiabatic mode is preferable for the detritiation of gas at any relative humidity. Under comparable conditions, KOG does not depend on the column diameter in the investigated range. A comparison of the main characteristics of the developed technology with those of the technology based on water vapor adsorption on molecular sieves shows clear advantages in terms of energy, operating cost, and detritiation degree with the same amount of tritiated water produced as a radioactive waste.
