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 family of carbon-fiber-reinforced carbon (and graphite) composites was developed for high-temperature applications. The method of screening for ablation resistance is described. The effects of filament orientation, matrix composition, and heat treatment are related to ablation performance. Between the angles of 15 and 75 deg a general insensitiveness to filament orientation is reported. Materials having a chemical vapor deposited matrix usually performed better than a carbonized organic counterpart. Graphitized materials are more effective than less ordered forms. Process control may be more important than specific composite constituents.
