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.

Validation plays a vital role in building trust in the predictive power of models and computational methods. Validation of a code consists of modeling documented real-world experiments and comparing the code-predicted response to the actual, measured response. In this panel session, we will discuss how these experiments are evaluated as benchmarks and used for validation of nuclear data and computational methods. We will also present an overview of four benchmark projects that aim to document different kinds of real-world experiments, with four panelists who chair the projects: Catherine Percher (LLNL), chair of the International Criticality Safety Benchmark Evaluation Project (ICSBEP), Mark DeHart (INL), chair of the International Reactor Physics Experiment Evaluation Project (IRPhEP), Thomas Miller (ORNL), chair of the Shielding Integral Benchmark and Database (SINBAD), and Germina Ilas (ORNL), chair of the Spent Fuel Composition (SFCompo) project. Additionally, Rowdy Davis (UNM), will present on his experience being a benchmark evaluator for ICSBEP, having recently submitted a benchmark on the University of New Mexico research reactor.
