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.

A compact diagnostic system for monitoring Hard X-Ray (HXR) in the KSTAR tokamak has been developed in this work. Its development aims for an extension of the counting rate limit, and a good time resolution in the hard X-ray diagnostic. The all-in-one compact HXR diagnostic system is based on NaI(Tl) scintillation detector, because this scintillator provides reliable identification of the X-ray energy spectra with high efficiency. And in addition, the electronic equipment such as preamplifier, main amplifier, high voltage power supply, and fast analog-to-digital converter (ADC) with a digital signal processor (DSP) system was built-in on boards as compact modules in the system. In particular, a fast ADC based on a DSP, and an amplifier with a shaping time of 100 ns was adopted to achieve 1 ms time resolution and a higher counting rate up to 1 MHz. This diagnostic system is intended to provide information on dynamic mechanisms of the high-energy electrons arising from when runaway electrons interact with plasma-facing components in the KSTAR tokamak.
