Doesn't Plutonium-238 occurs naturally along the Thorium decay chain? I believe that it's fairly easy (relatively speaking) to capture 238 from the Thorium nuclear reactor process.
A Thorium-based nuclear reactor prototype has already been successfully run for years at Oakridge National Laboratory- seeing the value of Plutonium-238, it might justify the cost of building a full grade Pu238-extraction nuclear reactor.
