Availability Notice


Companies looking to license reactors with different materials than the current U.S. fleet of lightwater zirconium-clad ceramic fuel are emerging as part of the push toward a more responsible energy economy. As such, the Nuclear Regulatory Commission is tasked with evaluating these new license applications. This report documents the current state of available experiment measurements, simulation capability, and historic knowledge and lessons learned required for evaluating sodium-cooled fast-spectrum metallic fuel, specifically U-10wt%Zr, up to 10at%burnup.
