The EU is propably somewhat fine. 62% of enrichment is done within the EU, but 30% comes from Russia. The problem is that such facitilites are really difficult to build, so it takes years and to the best of my knowledge none are planned. Germany shutting down its reactors however should help in terms of that.

However if we actually would want to help out our allies it becomes much much worse. The US has only one single plant, which is enough to supply 5% of the US needs, due to the US buying weapons grade uranium from Russia after the Cold War ended, which destroyed the US enrichment industry. South Korea does not have an enrichment plant at all and Japans is tiny. So both are basicly fully dependend on imports. If you can not import from the EU and Russia then only other option is China. The democratic world certainly needs more of these facilities. However nuclear proliferation is a massive problem. Enriching uranium allows one to build nukes. One of the reasons Germany is not shutting down its enrichment plant is to be able to make sure the US keeps up nuclear sharing. If the US for some reason would stop it, there at least used to be plans to allow Germany to build a nuke within a few months. I imagen similar things would be possible for other countries as well.
