For use in space, you need a reactor whose energy does not come out as hot neutrons. Even gamma rays would be better.
D-He3 (deuterium and synthetic helium) is attractive, except you have to make the He3 by making tritium and waiting for it to decay. pB (hydrogen and boron) is attractive, but much harder to make work than D-He3.
There is work on a D-He3 rocket, tagged "Princeton FRC", that they hope to loft for a trial maybe in 2035. Elon could get it tried out earlier, and ought to. We should be cranking tritium production up immediately so there will be enough He3 when we need that.
