The article says "Sweden, Finland and the U.K. are expanding or extending nuclear programs". AFAIK, 'new' nuclear energy facilities in Finland and the UK were planned a long time ago, and have been delivered late and terribly over budget.
Shutting down nuclear plants now is unwise, but building new ones is folly. In Italy, new plants would be ready by 2040 (my guess) the earliest. We need to move away from fossil fuels NOW, and solar + wind + batteries is the way to do it.
