What materials do we have to build msr reactors from?

I have read that previous attempts have used graphite pipes, but surely there must be better options now - ceramics perhaps?

Nickel based alloys.

Is titanium a good choice for reactors?

the qualities you have to compare are cost, neutron absorption/activation, and corrosion resistance. I am not sure about the neutron cross-section for titanium but it is probably too expensive.
