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.

A short ion bombardment greatly increases the hot saline etching or leaching of silicate glasses. The effect was observed for xenon, argon, neon, helium, and deuterium ion bombardment. From the relative values of the effect produced by the several ions, it was demonstrated that the effect is associated with the hot secondaries. The hot saline can cause the complete removal of material, thus producing a depression of an irradiated area, which was measured interferometrically, or it may cause a leaching of the cationic content of the glass and leave a silaceous residual film, which was studied by obtaining its spectral reflectivity. Other glasses may behave in an intermediate manner leading to some depression and some film residue. The glasses studied were soda-lime glass, light barium crown (28% BaO), and two facsimile radioactive waste storage glasses. The first two showed the enhanced etching, the first waste storage glass a tenacious film, and the second waste storage glass showed the intermediate behavior, some etching, and some film residue. The enhancement of the etching rate of the light barium crown glass was calculated as some fivefold, for the soda-lime glass about elevenfold. Enhancement of the leaching rate of the first waste storage glass was ∼2½ for helium ion bombardment and over 3½ for xenon or neon ion bombardment.
