"Heavy water reactors typically produce plutonium, which can be used in bomb-building".
All reactors which use uranium as a fuel produce plutonium regardless of the moderator used. The reactors used to produce the plutonium for the Nagasaki bomb were not heavy-water moderated but used graphite as the moderator.
A heavy-water reactor can be designed to use natural uranium as a fuel so it is possible to build a reactor without developing enrichment technology.
