Nuclear reactors are an unprecedented power source with a unique dilemma— they must meet people’s extreme expectations while being forced to adhere to stringent safety concerns. There is no end to the fighting in Ukraine in sight. Governments in Europe and Japan are leaning toward deployment of nuclear power plants more than ever. The governments of the United Kingdom and France are breaking away from dependence on Russia for energy resources and have revealed plans to build new nuclear power plants to secure long-term, stable energy supplies. In light of this movement in Europe, the Japanese government also announced that it would move ahead with the construction of new reactors for the first time since the Fukushima nuclear accident. Extreme expectations for nuclear power plants by policy makers will grow stronger under pressure to take measures against a soar in fuel prices and climate change.
