Summary
Kansai Electric has initiated plans to expand the Mihama Nuclear Power Plant in response to surging electricity demand driven by global decarbonization and digitalization. Japan’s electricity needs are expected to grow 40% by 2050, emphasizing the importance of stable energy sources like nuclear power. However, challenges persist, including aging infrastructure, delays in nuclear fuel reprocessing, and lengthy regulatory processes for new plant construction. The government aims to increase nuclear power’s share to 20% of the energy mix by 2040, but achieving this goal requires addressing public concerns and ensuring project feasibility. Experts highlight the need for government collaboration with private entities to mitigate risks and communicate the necessity of nuclear energy effectively.
