Nuclear reactor, nuclear, nuclear energy, nuclear japan, nuclear power, nuclear meltdown japan. second explosion occurred Monday at a nuclear power plant in Fukushima, Japan, and officials say three reactors at the plant are now having cooling problems.
The containment vessel is a heavily reinforced barrier that surrounds the reactor's core and provides a second layer of protection against the release of radioactive material.
The blast affected reactor No. 3, one of six reactors at the Fukushima Daichi plant about 150 miles north of Tokyo. A similar explosion occurred Saturday at reactor No. 1, and apparently did release some radioactive material.
When the earthquake occurred, the reactors automatically shut down. But even after the nuclear reaction stops, some radioactive materials continue to produce heat and require a constant flow of cooling water to prevent the core from melting.
It is likely that the cores of Nuclear reactor, nuclear, nuclear energy, nuclear japan, nuclear power, nuclear meltdown japan no 1 and 3 have partially melted government, officials said. They spoke after instruments detected a type of radioactive material near the plant that can be released when a fuel rod is melting.
