Switching off nuclear energy is a purely rational decision. The costs of nuclear power have always exceeded the benefits. Today, the costs of nuclear power are almost as high as those of gas-fired power plants.
If you add the follow-up costs: maintenance, dismantling, interim and final storage, the costs of nuclear power are between 5-10 times higher than the second most expensive form of energy.
Nuclear energy is and remains unprofitable. Except for the operators, who do not have to pay for nuclear waste etc.
