I wouldn't mess with enrichment, I'd just go for a breeder reactor, once you start producing pu that is much easier to separate and process into more fuel. Just start with a big enough pile of natural tubealloy and keep taking away fuel as it builds activity. Experience has shown that disused athletic facilities should be sufficient. What could possibly go wrong? ;-)
