A major obstacle to Lead Cooled Fast Reactor technology is the lack of structural materials that can withstand Pb corrosion at high temperatures (up to 700°C) and flow velocities. Recently established lead loop facility at the University of New Mexico is capable of testing materials compatibility with flowing molten lead up to 3 m/s flow velocity. In this talk, results from the recent compatibility tests at 500°C on a variety of engineering and model alloys including Fe-10Cr binary, ferritic FeCrSi and FeCrAl based alloys, and several austenitic steels including SS316 will be presented. The test conditions (oxygen levels in Pb, flow velocity, and temperature) are kept identical for each of these alloys during the tests. Initial analysis on 168- and 672-hour testing has been completed. The testing will be extended up to 4000 hrs. The results will also include long term lead/LBE compatibility testing of TIG and e-beam welded FeCrAl.
