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.

TerraPower, in collaboration with GE Hitachi, is driving toward the licensure, construction, and operation of the Natrium sodium fast reactor by the end of the decade. A key facet of the Natrium program is the development, qualification, and scaled-up fabrication of materials. This presentation will discuss the strategy for managing materials-related issues affecting design and recent progress toward our goal.
Presented by
Senior Manager of Materials Development and QualificationNatrium Sodium Fast Reactor ProgramTerraPower, LLC.
Greg Vetterick is currently Senior Manager of Materials Development and Qualification for the Natrium sodium fast reactor program at TerraPower, LLC. The MD&Q organization is responsible for material selection, new material development, core component supply chain, materials testing, material property database management, and material qualification for materials that are exposed to neutron fluence and/or sodium metal coolant. Before this, Dr. Vetterick held a number of management and technical roles at TerraPower spanning the Traveling Wave Reactor (TWR), Molten Chloride Fast Reactor (MCFR), and TerraPower Isotopes (TPI) programs . Prior to joining TerraPower, Dr. Vetterick received his Ph.D. in Materials Science and Engineering from Drexel University with a thesis on radiation damage tolerance of nanocrystalline materials. He also received a M.S. degree in Materials Science and Engineering from Iowa State University focused on development of wear resistant materials.
