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.

In this paper, we describe the reasoning that leads us to focus on the so-called curing process where a solid poly(α-methylstyrene) (PAMS) shell is formed from the initial solution phase. We demonstrate the existence of a percolation zone at about 55 wt% PAMS, beyond which the roundness of the shell can be expected to be irreversible. Using a simple model and a few supporting experiments to account for the rate of mass transfer of the fluorobenzene solvent phase, we show that curing rate is determined almost entirely by just a short exposure, to the sweeping gas, of the shells that graze the free surface of the curing bath as they move around in it. We propose here that specific control of the curing conditions at percolation would enable rounder mandrels.
