There are some things that have become irrelevant for now, particularly the need for a stellite alloy. Most of the things we are doing differently from ORNL in our division for thermal MSRs is based on the progress in materials and CAD since the winding down of the ORNL MSRs.
There are a lot of promising mostly mix-able design choices in MSRs that have become apparent in the last few decades, so we are never fully committed to a particular set.
