Very interesting technology - not quite sure what the difference is between a 'fast reactor' and a 'fast breeder reactor' - will have to study on that - they sound the same.
Just the increase of operating temp of the reactor gas will increase the thermodynamic efficiency of the reactor by a tremendous amount (proportional to the cube of the temps).
Studying on diesels and the the rail injection system last nite - stumbled across the simple fact that large diesel engines can achieve actual (not just theoretical) thermodynamic efficiencies of 50% - which is very good for an internal combustion engine.
Diesels, because of their higher op temps (some incorrectly state because of higher compression) are MUCH more efficient than gasoline engines can be. Gas engines top out around 30-35% max thermo efficiency.
Due to changes in turbine materials compositions - they can now operate in the extreme high temp ranges - up to 2350 F now - push their efficiencies into the 70% range when used with two stage systems (ie. a secondary turbine =combined-cycle= powered by the exhaust - no additional energy consumed).

This EM2 nuclear technology has a lot of 'romance' to it the way it is presented in the article. Kinda like reading some of the very old Popular Science articles about 'the future'. *s*
