Thorium Fuel Cycle Using Fusion Neutron Source

Postby Enginerd » Thu Aug 16, 2012 1:15 am

in late May 2012, Magdi Ragheb from the University of Illinois presented at the . He discussed his work on using electrostatic & electrodynamic neutron generators to operate or kick start LFTR style thorium reactors. As a neutron source, the polywell can either be used to breed all the needed U233 from thorium (so the LFTR need not also be a breeder), or can be used to simply kick start a LFTR which does its own breeding (such that no initial charge of Uranium or Plutonium is needed to begin breeding).

Lots of discussion and pics of polywell.

He concludes that even if the polywell by itself never hits positive Q, it can be used as-is as an excellent neutron source in conjunction with a LFTR. Combining the two allows for a hybrid fusion-fission reactor that can produce essentially unlimited energy.

While a LFTR is obviously not as clean as a working positive Q polywell burning pB11, such a hybrid system sure beats the heck out of burning coal. Running a LFTR using a polywell beats scrounging about for an initial load of enriched uranium to kick start a LFTR. Using a polywell as a neutron source to breed Thorium into U233 might well simplify the LFTR design.

Anyway, I'd never considered the idea of using a polywell simply as a neutron source leading to net power from a fission reaction. Interesting idea.

Polywell as a neutron source to make plutonium and bad guys. Hummmmm. Isn't Iran pursuing a polywell program?[/quote]
