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.

Two assemblies of self-powered in-core detectors have been tested in the Oconee 2 pressurized water reactor for more than 1 yr. The assemblies contain both prompt-responding hafnium and delayed-responding rhodium detectors. Four hafnium detectors are paired with four rhodium detectors in each assembly. The purpose of the experiment is to define the characteristics of the prompt and delayed detectors operating together in pairs. Data from the experiment show that the prompt detectors need to be calibrated on-line and that the rhodium detectors paired with them can be used to make the calibrations. The response of the hafnium detector to a reactor scram is given.
