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A model has been developed to explain the composition of gas withdrawn from the Gasbuggy chimney following an underground nuclear explosion to stimulate the recovery of natural gas. The model assumes that homogeneous, gas-phase reactions occurred during cavity formation among the species formed from the volatile fraction of 1550 tons of formation per kiloton of explosive yield. After chimney collapse, additional heterogeneous reactions occurred involving this gas mixture and natural gas which significantly altered the composition. This work suggests two criteria for choosing the shot points for future explosions: the rock should be free of solid carbon, and relatively rich in carbonates. The application of these criteria is expected to reduce significantly the radioactive burden of T and 14C found in the hydrocarbons subsequently produced.
