I'm interested to see what Moltex can do to simplify matters:

Instead of pumping the salt around, they plan to leave it sitting in stainless steel tubes, and use simple convection to extract the heat. Oak Ridge rejected this idea in the 1950s because they were trying to power an aircraft, but convection makes more sense when the reactor isn't moving.

LANL built a reactor like that, with liquid fuel in tungsten capsules. It was called LAMPRE.

Tantalum capsules. Molten plutonium is darn corrosive.
