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.

In order to extensively and simultaneously analyze frequencies of fluctuations of the end-loss ion current, we prepared three types of analog-to-digital converters (ADC) whose sampling frequencies are 62.5 kHz, 333 kHz and 64 MHz, respectively. The low and intermediate frequency ADCs have 20 channels. The high frequency ADC has a single channel and analyzes the summed signal of the MCP detector. We observed the fluctuations of Alfvén ion cyclotron (AIC) mode and the beat phenomenon appeared in the end-loss ion current. On the energy distribution functions of the end-loss ion, we have already observed the gentle humps. We found the relation between the gentle humps and the AIC waves observed in the end-loss ion current, and confirmed by the pitch angle analysis of the beat fluctuation that the AIC waves significantly influenced the trapped ion to transport into the loss region.
