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 new capsule design was prepared and tested at the High Flux Advanced Neutron Application Reactor (HANARO) for neutron irradiation of the core materials of research reactors at a low temperature (of <100°C). The capsule was first designed at HANARO to have the coolant flow through the capsule to cool down the irradiation temperature of the specimens. The safety of the newly designed capsule should be fully checked before irradiation testing. Out-pile performance and endurance testing before HANARO irradiation testing was performed using a capsule in the HANARO out-pile test facilities. The new capsule had a much higher coolant flow-induced vibration than a standard capsule, resulting in fatigue failure at the rod tip of the capsule. The lifetime of the rod tip was greatly improved by changing the material from Type 304 stainless steel to Type 316L stainless steel and by changing the welding method from tungsten inert gas welding to electron beam welding. With the optimized design, the capsule was successfully irradiated at low temperatures of <100°C for up to eight cycles (6075 MWd) at HANARO.
