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.

Speckle interferometry is an optical technique able to measure and to image displacement of surface. An original setup is used to investigate the measurement of a deformed cylinder as a feasibility study. This shape allows us to determine the capability of this technique to measure nuclear fuel rod cladding. Indeed, in a nuclear reactor, the fuel rod undergoes different physical phenomena that induce dimensional changes in the cladding. The aim of this study is to quantify the amplitude of local ridges appearing on the outer cladding surface due to the "hourglass shape" assumed by the pellets under irradiation.Because of the environmental constraints imposed by testing, an optical measuring device will be used to experimentally characterize mechanical strain induced by the interaction between the cladding and the fuel pellets. The aim of this paper is to examine the experimental feasibility of speckle interferometry using model samples.An experimental setup based on the speckle interferometry technique was therefore implemented to measure local deformation in nuclear fuel cladding. Different experiments on model samples have shown that this technique is well adapted to the measuring range, shape, and condition of the surface as well as the working distance.
