This report documents the selection of materials participating in the currently ongoing corrosion/erosion tests in LANL Development of Lead-Alloy Technology and Applications (DELTA) loop, a facility designed to study the long-term corrosive effects of liquid lead-bismuth eutectic (LBE) on structural materials for high temperature applications in advanced reactors, accelerator-driven systems and spallation sources. In this suite of experiments, LBE temperature in the DELTA loop test section is 500°C. Oxygen sensors are used to maintain an LBE Oxygen concentration of 1x10^-6 to 1x10^-8 wt%. Unique to the experimental conditions is the LBE high flow-rate of 3-3.5 m/s in the test section. Results obtained in these corrosion tests represent a substantial extension from existing experimental data currently limited to LBE velocities of maximum ~2 m/s.
