The most interesting thing for these is liquid lithium metal--especially a great solution on diverter. For the wall neutron flux this is unfortunately seen as a "materials issue" (someone else's problem). It is a bit stalled out until we can build something with high enough neutron flux for testing.

Exciting news on the liquid Li, but I'm a bit dejected to hear about the wall.
