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.

Brazing techniques for joining dissimilar materials considered for tube-to-armor joints of high-temperature graphite space radiators have been investigated. The combinations tested consisted of Cb-1Zr and type-316 stainless-steel alloys, each brazed with developmental alloys to Graphitite-G and an expanded form of pyrolytic graphite. Stability test results are reported for specimens brazed and aged 500 h at 1350°F (734°C) or thermally cycled 500 times between 350°F (177°C) and 1350°F under a pressure of 10−5 torr (max). Brazing and thermal stability tests indicated that compatible braze bonds can be made between the graphites and potential tube materials.
