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.

Plasma interaction with first wall and interior reactor chamber components is an influencing factor in the design of inertial fusion facilities. The concept of a liquid metal wall, in which a circulating lithium curtain would be used, has been considered in many studies. The interaction of plasmas with moving liquid metals is a complex subject due to the influence of hydrodynamics, evaporation and droplet formation, nucleation and agglomeration of condensed particulates. To gain an understanding of some of the specific details of this interaction an experimental setup of an arc-generated plasma interacting with a liquid lead pool has been designed, constructed and operated. This simulation of the plasma-liquid interaction focuses on the particle condensation of the liquid metal after plasma interaction. The experiment generates transient high-density plasma over 50 s pulse duration. Plasma characteristics are determined by various diagnostics. A set of collection substrates are arranged to collect nucleated particulates condensing from the evolving plume. Particulate size and distribution are analyzed numerically using digital images.
