What happened at the Fukushima reactor in Japan?
What happened at Fukushima? Systems at the nuclear plant detected the earthquake and automatically shut down the nuclear reactors. Workers rushed to restore power, but in the days that followed the nuclear fuel in three of the reactors overheated and partly melted the cores – something known as a nuclear meltdown.
What caused the nuclear meltdown in Japan?
Following a major earthquake, a 15-metre tsunami disabled the power supply and cooling of three Fukushima Daiichi reactors, causing a nuclear accident beginning on 11 March 2011.
How was the Fukushima disaster handled?
Plant workers were put in the position of trying to cope simultaneously with core meltdowns at three reactors and exposed fuel pools at three units. Automated cooling systems were installed within 3 months from the accident. A fabric cover was built to protect the buildings from storms and heavy rainfall.
What year did Fukushima meltdown?
March 11, 2011
Fukushima nuclear disaster/Start dates
March 11, 2011: An Earthquake Precipitates Crisis 3:27 p.m.: The earthquake sets off a tsunami. The first wave arrives at the Fukushima Daiichi Nuclear Power Plant in the form of a 13-foot-high wave, which is deflected by a sea wall built to withstand waves up to 33 feet high.
Is the Fukushima power plant still leaking?
The accumulating water has been stored in tanks at the Fukushima Daiichi plant since 2011, when a massive earthquake and tsunami damaged its reactors and their cooling water became contaminated and began leaking. TEPCO says its water storage capacity of 1.37 million tons will be full around the fall of 2022.
What other famous places experienced a nuclear meltdown?

How much water does a nuclear power plant need?
Most electric power plants require water to operate. Nuclear and fossil fuel power plants drink over 185 billion gallons of water per day. Geothermal power plants add another 2 billion or so gallons a day. Hydropower plants use water directly to generate power.
What happens during a nuclear meltdown?
According to the Scientific American , during a nuclear meltdown, core material overheats, either due to a runaway reaction or loss of coolant. The extreme temperatures can cause damage to the reactor, partially melt the nuclear fuel and contaminate any remaining coolant with radioactive material.
What is the biggest nuclear power plant in the US?
The Largest Nuclear Power Stations In The United States. A nuclear power plant located near Tonopah, Arizona, the Palo Verde Nuclear Generating Station is the largest nuclear power plant in the US.
What is a nuclear power plant disaster?
The Fukushima nuclear disaster is a series of ongoing equipment failures, reactor meltdowns, and releases of radioactive materials at the Fukushima Daiichi Nuclear Power Plant , following the Tōhoku earthquake and tsunami on March 11, 2011. The plant has six separate Nuclear reactors maintained by the Tokyo Electric Power Company (TEPCO).
