[ RadSafe ] " House Committee Passes Bill to CreateUSIsotopeSupply "

That is my understanding, also.  Two factors come into play: the neutron absorption cross-section of Mo98 vs. the fission producing neutron absorption cross-section of your fissile material, and the problem of isotopic separation of Mo98 and Mo99 (which would be very hard) and the chemical separation of Mo from the other fission fragments and remaining fissile material (and whatever else there is).  If you want either a lot of Mo99 or concentrated Mo99, I think you need to go the fission route.

I forgot to mention, that with fission Mo-99 large (high activity) can be 
manufactured.  This is not the same with Mo-99 produced from Mo.
