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.

Reactor noise measurements at Pakistan Research Reactor were analyzed for the magnitude and frequency spectrum of the fluctuation of neutron density. The measurements were aimed at determining the effect of (a) the magnitude of reactor power, (b) coolant flow rate, and (c) position of control rods on the fluctuation of reactor power. Two peaks in the power spectral density of neutron noise are explained to be due to control rod vibration. A one-dimensional thermal-hydraulic model of the reactor core was also developed to explain the remaining noise spectra on the basis of coolant temperature fluctuation.
