Check the older postings on this board.. there was some discussion about this.. Actually, you can use the fast neutrons directly, without thermalizing, to fission U238, as is done in most thermonuclear warheads. For a fairly good intro to this sort of physics, the High Energy Weapons FAQ is a good start. Find it at http://www.fas.org/.

1E15 n/sec is many, many orders of magnitude greater than anybody has done in a fusor (or is likely to.) 1E6 is doing great..

Shielding??? At 20 kW, the neutron flux from the fission is going to be mighty impressive. This is the kind of power that early natural uranium reactors running with graphite moderators. I think the TRIGA reactors run at this kind of average power (although the peaks are much higher in a TRIGA).
