Around 4.3 million voted for a nuclear power restart, and 1.5 million against. However, for the yes side to win, 5 million votes were required.
The initiative for the referendum was taken by the opposition. The proponents emphasized the need for a stable energy supply and reduced dependence on energy imports in the event of a blockade from China.
