They all need some enrichment, but then apparently it’s still very hard to go from a civilian reactor to weapons-grade uranium. Just, I guess, much easier than from a heap of coal.

I understand that with adequate supervision from the IEA proliferation is generally a non-issue.

What is considered "adequate supervision" is of course debatable. Lithuania has made many complaints regarding it's safety concerns of the newly opened Belarusian power plant to the relevant international authorities - which have all so far fallen on deaf ears.

Lithuania had its own nuclear power plant, which is currently being decommission, so it's not that they are just playing the NIMBY card without knowing what they are talking about.

I totally sympathise. In this case though, this isn’t to do with proliferation, right?

But ultimately both are semi-opt-in so I guess your point stands.
