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.

For a practical air detritiation system, the effect of the residual tritiated water left on the silica was demonstrated. The residual tritiated water significantly reduced the detritiation factor of the air detritiation dryer. To maintain the detritiation factor more than 350, the space velocity lower than 140 h-1 should be selected for the design and the operation of an air detritiation dryer packed with silica gel. The HTO/H2O separation factor evaluated using a dryer with residual tritiated water was 1.17 on the average. Silica gel is superior to commercial molecular sieves in dehydration ratio at room temperature. Dehydration from silica gel was dependent on the accumulated amount of purge gas, independent on flow rate. Dehydration from silica gel showed a slight pressure dependency. Consequently, silica gel is a promising desiccant agent for air detritiation dryer.
