The Westinghouse team, which includes General Atomics, Idaho National Laboratory, Massachusetts Institute of Technology, Texas A&M University, Edison Welding Institute, Los Alamos National Laboratory, and Southern Nuclear Operating Company, will work to develop fuel and cladding concepts with strong potential to replace the currently used zirconium uranium oxide (Zr+UO2) fuel system with an enhanced accident tolerant fuel. This will be done by investigating a new fuel system comprised of a cladding capable of surviving high temperatures and significantly reducing any in-core reactions with steam and a high density fuel of increased Uranium-235 content still at 5% enrichment and increased thermal conductivity.
