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 large, vertical shock tube is used to explore the breakup and mitigation effects of liquid layers expected from the hydrodynamic shock generated in an inertial fusion reaction. Single and multiple layers of water are tested at two Mach numbers, 2.12 and 3.20. X-ray radiography techniques are used to image the breakup of the water layer resulting in a quantitative measure of the mass fraction distribution of water after shock impact. The amount of breakup is increased with the addition of multiple layers and the increased breakup decreases the end wall impulse. The speed of the transmitted shock wave can be reduced by 50% and is a weak function of the number of layers. The peak pressure at the end-wall of the shock tube is significantly increased due to the high impulsive force of the single liquid layer, however this pressure is substantially reduced when multiple layers containing the same mass of water are used.
