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.

The 30-deg white neutron beam at the Research Center for Nuclear Physics (RCNP) cyclotron facility has been characterized as a probe suitable for testing of single-event effects (SEE) in semiconductor devices in the neutron energy range from 1 to 300 MeV using the 392-MeV proton incident reaction on a 6.5-cm-thick tungsten target. The neutron spectrum obtained by time-of-flight measurements reproduced the terrestrial neutron flux distribution at sea level, and neutron intensity increased by a factor of 1.5 × 108 became available. The average neutron intensity and spectrum in the energy region from 10 to 100 MeV at RCNP were almost the same as those at the Weapons Neutron Research (WNR). The calculated RCNP neutron flux using Particle and Heavy Ion Transport code System (PHITS) generally agreed with the measured RCNP data within a factor of 2. The neutron density per pulse at RCNP, which is around 500 times lower than that for WNR, has the advantage in reduction of the pileup probability of single-event transient currents and false multiple-bit upsets. Such conditions at RCNP are suitable for accelerated SEE testing to get meaningful results in a realistic time frame.
