Every single NPP that is not based on fast neutron reactors (all western ones) running on rods with any U238 content (all currently used rods) could produce nuclear weapon material - plutonium-239.

Nuclear weapon material is mostly Pu239 that created in rods as they work in reactor.

The main problem with Pu239 is not creating it, but separation from the depleted NPP fuel. AFAIK, Finland have no abilities to extract plutonium from depleted NPP fuel.

So, every country that have NPP produce nuclear weapon material. But very few have an ability to extract and enrich it. Finland is not in that list, so it could produce only a raw material on any of its NPP that have to be processed to get nuclear weapons material in one of more advanced country with sufficient nuclear weapons material processing power like USA, Russia, France or China.
