In another significant boost to commercial deployment of accident-tolerant fuel (ATF) at existing nuclear reactors, the first 18-month fuel cycle test of Framatome’s GAIA Enhanced Accident Tolerant Fuel (EATF) at Southern Co.’s Vogtle 2 has “demonstrated expected results and excellent performance,” Framatome said on Feb. 2.
Koroush Shirvan isn’t a zoologist, but he’s well acquainted with moose, bison, cobras, and falcons, to name a few. Like anyone working in the world of advanced research on nuclear power, this assistant professor in the Massachusetts Institute of Technology’s (MIT) Nuclear Science & Engineering department deals daily in initialisms and acronyms, which for Shirvan include MOOSE, BISON, COBRA, FALCON, and dozens more.
Ask Dr. Tatiana Ivanova, a long-time nuclear engineer and head of the Nuclear Science division at Paris-based intergovernmental organization Nuclear Energy Agency (NEA), why so much activity is ongoing to transform nuclear fuel — and her answer is simple: “It is the principal part of nuclear power plants.” Fuel design optimization is “a cornerstone for the industry to deploy new, modern fuel for light-water reactors [LWRs], advanced reactors, and small modular reactors,” she said.
Three of the largest nuclear suppliers in the United States are working with the U.S. Department of Energy (DOE) to develop new accident tolerant fuels for the nation’s fleet of reactors.
The first accident tolerant fuel assemblies containing both modified cladding and pellets have been loaded into until 2 of the Vogtle nuclear plant in Georgia, Southern Nuclear and Framatome announced 5 April.
