...and human flash quite rapidly. So if your NaOH radiator leaks you might get sprayed with meat dissolving viscous liquid.

I think practical applications would transfer the heat to pure water in a heat exchanger instead of delivering the NaOH directly to the radiator. In a well insulated system, the losses should be minimal

And trying to rinse it with water (which is probably the first thing that anyone would do) will only make things worse.

No, if the sodium hydroxide is already in solution then diluting with copious water is one of the best ways to deal with a splash on skin. You're right that adding water makes the problem worse if you have e.g. a spill of prills to clean up.
High concentrations of NaOH in water are strongly basic. It will corrode many oxide-based ceramics (like toilet bowls) and aluminum, but it's no problem for most other common metals and plastics.
