The Aircraft Reactor Experiment-Design and Construction1
The Aircraft Reactor Experiment was designed for operation at temperatures in the region of
1500ºF (1100 K) at a power of 1-3 MWt with a fluoride-salt fuel circulating in a heterogeneous
core. The moderator was hot-pressed BeO blocks cooled by circulating sodium. The heat
produced was dissipated in water through hot liquid-to-helium-to-water heat exchange systems.
All sodium and fuel circuit components were made of Inconel fabricated by inert-gas (Heliarc)
welding. The system was heated to design temperature by means of electrical heating units
applied over all parts of the system. Instrumentation and control of the experiment were fairly
conventional. For the most part, standard instruments were modified slightly for the hightemperature
application. The reactor system was constructed and operated in a building
specifically provided for the purpose.

I wonder if a Pebble Bed reactor could be used in cars as well as aircraft.......................
