How do you make it do mechanical work?

What would be the working fluid for the heat engine?

That's what the turbine is for: 300 HP -- we just replace the combustor can
at the back.  The working fluid is hot air.

The the 618°C temperature that you quote for the RR300 is MGT
(measured gas temperature) which is actually the turbine outlet
temperature.  As such it will be 2-300° C below the Turbine inlet
temperature.  Small gas turbines like the RR300 with uncooled turbine
blades have turbine inlet temperatures in the range of 850-1050°C.

A gas turbine with 618°C inlet temperature would be lucky to reach 15%
efficiency.  And with a pressure-sapping heat exchanger to heat the
air instead of a combustor (not to mention reduced turbine mass flow
due to absence of fuel) the efficiency would likely be even worse.

Thanks for the clarifications!  It might still be feasible hopefully --maybe
a ~3 MW reactor outputting 1000 °C .
