If Norway really wanted to invest into more energy production, then infusing more research money into tidal power would likely results in better returns than nuclear.
Sweden mostly need nuclear power in order to stop burning oil/biofuel. The southern part of Sweden regularly need more energy than get produce, and thus the oil plant located there need to operate at almost 24/7. It is the single largest source of pollution by a very large margin. A nuclear plant in that region would also help Denmark reduce their footprint when the weather is sub optimal for wind production. More wind energy is likely not going to cause much harm (except when placed onto nature reserves), but the issue with the oil plant is also not going to be solved by more wind energy. Denmark is already well over 100% wind capacity.
