Hey Radsafe,
       Hmmmmm.  Whether one uses sodium  or some other material in the 
primary loop of a reactor
on a space ship, one can use fast neutron fission to possibly avoid using  
highly enriched
Uranium (or whatever) as a fuel.  Just use the usual 5% or whatever  
reactor grade enrichment in
U235.  Hmmmmm, sounds much less expensive than using 95% enriched  Uranium.
       Guess the mainland Chinese will have a  spaceship, based on all 
this, off the ground soon
(using technology the USA and other countries developed!!!!).
       Have a good  weekend!!!!      Regards,    Joseph R.  (Joe) Preisig,
