A new test loop (Lobo Lead Loop) capable of forced convection of molten lead up to 700°C was established at the University of New Mexico. Computational fluid dynamics (CFD) was used to design the specimen holders to achieve 3 m/s flow velocity. Initial testing was completed at 500°C for up to 672 hrs on 16 alloys including ferritic (both silica and alumina forming), ferritic martensitic, and austenitic alloys under controlled oxygen levels in the lead. Currently the testing is underway to reach >4000 hrs on same alloys. Preliminary cross-sectional SEM investigations show various morphologies of protective oxides on all the tested specimens. More detailed studies will be conducted along with the longer duration testing. The details of the loop will also be presented along with the transition to 700°C testing and efforts on radioisotope retention studies.
