So you say the lithium is a moderator in these?

In my experience, metal cooled reactors are fast reactors (sodium, for instance, has a small cross section). The lithium cross section is big, an absorber, per se, but not so much a slower down, per se, like water or carbon. Maybe this is a carbon moderated reactor (like Chernobyl)?
