I don’t think any of these statements are true, in particular the “failure” and import needs you mention. Sweden has been a net exporter for most of the past years and 2022 they exported most energy of everyone in the EU: Sweden remains Europe’s largest net power exporter.

And the current Swedish government are absolutely talking about new reactors:

Finance Minister Elisabeth Svantesson (M) and the Minister for Civil Defence, Carl-Oskar Bohlin (M), promise that new nuclear power will begin to be built in Sweden before 2026.

They also seem to be abandoning their previously communicated plans of opening old ones:

The Tidö agreement promises an investigation to review the possibilities for restarting the Ringhals 1 and 2 reactors.

But an internal memorandum written by SD’s top official in the steering group for Vattenfall testifies that KD refuses.

SD can drop the demand to restart one reactor - the party leadership is now being asked to act to save the other.
