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.

Three mathematical models for use in calculating the stresses and displacements in two-, three- , and four-layer pyrolytic carbon and silicon carbide coatings on microspheres of (Th,U)C2 or (Th,U)O2 during reactor service have been previously described. In these models it is assumed that pyrolytic carbon changes dimensions anisotropically and will creep under fast-neutron irradiation, silicon carbide is dimensionally stable and undergoes no creep, and an internal pressure is generated due to gaseous fission products. Comparison of the results predicted by these mathematical models with irradiation tests shows agreement with diametral changes of two-layer fuel particles. Coating failure, presumably due to stress, occurred only in those samples with high calculated stresses.
