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.

Computation and simulation have a rich history in the nuclear enterprise. When combined with modern theory and informed by experimental data, virtual scientific exploration can lead to unparalleled technological advances. But while simulations can be predictive, they can also be dead wrong, leading to the potential for devastating errors in judgment. In this panel session we will explore some of the triumphs of computation and dissect those instances when overreliance on simulation has led us astray. With real-world examples, we will show how the nuclear professional community has been at the forefront of computation and how nuclear science remains at the cutting edge today by using high-performance computing, machine learning, and other methods.
