Core Viewpoint - The article discusses the revival of nuclear power in Japan, highlighting Kansai Electric Power's plans to initiate the construction of a new generation nuclear power plant, marking a significant step towards achieving the country's decarbonization goals [1][4]. Group 1: Nuclear Power Development - Kansai Electric Power will soon announce the commencement of geological surveys for a new nuclear power plant at the Mihama site, which is the first concrete step towards new nuclear construction since the Fukushima disaster [2][4]. - The last new nuclear power plant in Japan was the Hokkaido Electric's Tomari Unit 3, which began operation in 2009 [2]. - The new plant is expected to utilize an "innovative light water reactor," which is considered to have higher safety standards [2]. Group 2: Regulatory and Construction Timeline - Geological and topographical surveys are the initial steps in the construction process, followed by basic design formulation and application to the Nuclear Regulation Authority [2]. - The entire process from survey to operational status is projected to take approximately 20 years, including necessary safety certifications [2]. Group 3: Current Nuclear Power Status - Currently, only the Mihama Unit 3 is operational, while Units 1 and 2 have been decommissioned [3]. - The Takahama Unit 1 is set to become Japan's first nuclear unit to exceed 50 years of operation in 2024, with Mihama Unit 3 reaching the same milestone in 2026 [3]. Group 4: Government Policy and Future Projections - The Japanese government’s 7th Energy Basic Plan aims to maximize the use of decarbonized energy sources, including nuclear power, and has removed previous language advocating for reduced reliance on nuclear energy [3][4]. - By 2040, nuclear power is projected to account for approximately 20% of Japan's energy mix, up from 8.5% in 2023, while the share of thermal power is expected to decrease significantly [4].
