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.

Simulations of ignition-scale hohlraums show that the addition to the hohlraum of a submicron-thick Au/B interior liner containing [approximately]20 to 40 at. % B likely reduces laser backscatter by reducing the stimulated Brillouin scattering. By reducing the backscatter, the amount of energy available to compress the inertial confinement fusion capsule is increased while the likelihood of laser damage at National Ignition Facility (NIF) is minimized. A specialized magnetron cosputtering process is used to fabricate Au/B liners between 0.6 and 1.2 m for use on hohlraums shot at NIF to the atomic concentrations of 20 to 40 at. % B. We will discuss recent process improvements, such as LabVIEW process automation, in situ rate and thickness measurements, and optimized coating setup, all of which have increased the hohlraum yield and hohlraum throughput as well as increased control and confidence in Au/B liner thickness and B concentration uniformity and reproducibility. We will also discuss effects of various leaching mechanisms affecting B concentration in the Au/B liner.
