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.

Tritium must be strictly defended in tritium systems because of its permeability and radioactivity. Detritiation devices are required in tritium systems, such as the glove box detritiation system, the vent detritiation system, and the air detritiation system in ITER. The method of catalytic oxidation and adsorption is widely used for air detritiation, and metal gas getter is used in glove box detritiation. Here, a Ce-based oxide-loaded honeycomb catalyst is prepared as a multifunctional detritiation catalyst. The properties of the Ce-based oxide and catalyst are characterized by X-ray diffraction, N2-adsorption/desorption (Brunauer-Emmet-Teller method), and H2 temperature programmed reduction. The catalytic performance is tested under both O2-lean and O2-rich atmospheres. Results indicate that the Pt/Ce0.7Zr0.3O2 honeycomb catalyst fully oxidizes H2 at room temperature with high space velocity (3.2 × 104 h−1) when oxygen is sufficient. When oxygen is deficient, H2 is also fully oxidized by the catalyst at 200°C, with the oxygen supplying from the support. A detritiation test using tritium as reactant is also carried out, and the results verify the feasibility for detritiation application. An improved detritiation reactor is designed and built based on the multifunctional catalyst.
