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.

Pressure Sensitive Paint (PSP) was investigated as a potential measurement technique for studying advanced heat exchanger designs. An experiment was setup to emulate a single rod in a helical coil steam generator (HCSG) being subjected to flow. Background, wind-off, and wind-on images were taken with a CCD camera while the PSP was under excitation light from a UV lamp. Instantaneous images were taken at 7 fps at Re 30,000. Analysis of the pressure field images found the average wind-off pressure to be 102.49 kPa and the average wind-on pressure to be 103.24 kPa. Such small changes in pressure can be verified with dynamic pressure transducer measurements also taken at the surface of the rod. The present study only discusses the results from the instantaneous pressure sensitive paint images captured from the experiment. Future work looks to make use of the sensitivity of pressure field measurements the PSP is capable of within a larger scale helical coil steam generator model.
