- What major event did this reactor survive in 2011?
- The reactor, located 100 kilometers north of the Fukushima Daiichi nuclear plant, survived the 2011 earthquake and tsunami, which caused meltdowns in three reactors at Fukushima. Onagawa's three reactors successfully maintained vital cooling systems and shut down safely.
- Why was the Onagawa Nuclear Power Plant's reactor 2 shut down?
- The Onagawa Nuclear Power Plant's reactor 2, which had restarted after the 2011 earthquake and tsunami, was shut down again due to a malfunction in a neutron data device.
- What are the implications of Japan's push for more nuclear energy?
- Japan's government is promoting the use of nuclear energy as part of its plan to achieve carbon neutrality by 2050, but concerns remain, particularly after a recent earthquake in January 2024 caused damage to two nuclear plants and highlighted deficiencies in evacuation plans.
- What happened to other Japanese nuclear reactors following the 2011 disaster?
- Following the Fukushima disaster, Japan shut down all 54 commercial nuclear power plants for safety checks and upgrades. Reactor 2 at Onagawa was the 13th of 33 operable reactors to restart.
- Were there any safety concerns or radiation leaks during the reactor's operation?
- Tohoku Electric Power Co., the plant's operator, stated that the reactor was operating normally and there was no release of radiation to the environment. The shutdown was intended to allow for a re-examination of the equipment to alleviate public safety concerns.
