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 technical note describes the influence of the transients and corrective additives on the distribution of loosely bonded forms of solid-phase corrosion products between the equipment surfaces and the primary coolant of a naval reactor plant. It is shown that the concentration of loosely bonded corrosion products increases by tenfold during the transient, and the feeding of corrective additives allows a several-fold reduction in the rate of their resedimentation on the internal surfaces of equipment, and as a consequence, improvement of corrosion product removal efficiency by cleanup filters. The proposed solutions allow removal of up to 70% of loosely bonded corrosion products from the coolant using standard filters.
