Experience with converting HWR fueled with NU to LEU?

  1. Jun 26, 2012 #1
    Are there any experience converting HWR initially fueled with NU to LEU, besides the National Reserch Reactor in Canada which went from NU to HEU to LEU?

    I'm aware that AECL developed a CANFLEX fuel design which uses slightly enriched U. I believe enrichment was increased up to 1.6%, but I've seen comments regarding 1.8%.

    KAERI (Korea) and INR, Pitesti (Romania) research institutes have studied SEU fuel.
