Also, there are plenty of newer 'small reactor' designs. You would have been better served to bring up one of the many trashcan types used in our subs, aircraft carriers and at research facilities. But even those require infrastructure that couldn't be moved, and the neutron radiation they generate would leave tell tale signs.
We don't use breeder reactors on aircraft carriers or subs. SL1 was smaller and more portable, which is why I mentioned it. It was designed to be deployed as a mobile device for the Army. The breeders needed for plutonium generation are smaller yet.
Berated poly and water would sufficiently block tell-tale neutron irradiation.
