Explanation

The correct answer is Japan. In July 2007, a powerful earthquake known as the Niigataken Chuetsu-oki earthquake struck the Niigata prefecture in Japan. This earthquake caused a fire and several radioactive water leaks at the Kashiwazaki-Kariwa Nuclear Power Plant. At the time, this facility was the largest nuclear power station in the world by net electrical power rating. While the leak was reported as being below safety limits, the incident led to a long term shutdown of the plant for safety inspections and structural reinforcements.
