They differ a lot depending on whether they are pressurized water
reactors, boiling water reactors, sodium cooled,... One advantage
of molten-salt reactors is that they aren't pressurized.
True. In the last operating thorium reactor on this planet, the MSRE
at Oak Ridge that was shut down in 1969, even with tough Hastelloy
plumbing there was some damage to the metal in the pipes of the MSRE
caused by neutrons and other forms of radiation, however in a full
sized production reactor the pipes would be largely protected by the
Thorium blanket that breeds the U233.
I think its a scandal that a extraordinary promising technology like
liquid fueled Thorium reactors has been frozen like a fly in amber for
over 40 years because nobody will spend a dime on it.

Given the scare that the "china Syndrome" and its hype generated,
there has been little interest in a public discussion of reactor design.
The Greenies have caused this, in their hysterics.
