The largest nuclear power plant ever built is the Kashiwazaki-Kariwa Nuclear Power Plant in Japan. The plant is located on the coast of the Sea of Japan and is operated by Tokyo Electric Power Company. It has a total of 7 reactors, with a total installed capacity of 8,212 megawatts, making it the largest nuclear power plant in the world by capacity.
The plant features six boiling water reactors (BWRs) and one advanced boiling water reactor (ABWR). The BWRs have an installed capacity of 648 megawatts each, and the ABWR has an installed capacity of 1,356 megawatts. The plant has been in operation since 1985 and it’s capable of producing enough electricity to power over eight million homes.
The Kashiwazaki-Kariwa Nuclear Power Plant was designed to withstand earthquakes, and it has been tested against earthquakes of magnitude 6.8 on the Richter scale. However, in 2007, the plant was damaged by an earthquake that exceeded its design limits, causing a shutdown of all reactors. Since then, several of its reactors have been restarted after passing the new safety standards established by Japan’s Nuclear Regulation Authority (NRA) after the Fukushima Daiichi nuclear disaster.
