Was Fukushima worse than Chernobyl?

Is Fukushima still leaking radiation 2020?

The nuclear disaster at Fukushima sent an unprecedented amount of radiation into the Pacific. … The contaminated water has since been used to cool the destroyed reactor blocks to prevent further nuclear meltdowns. It is currently being stored in large tanks, but those are expected to be full by 2022.

Is Fukushima Daiichi still operating?

It commenced commercial electrical production on March 26, 1971, and was initially scheduled for shutdown in early 2011. In February 2011, Japanese regulators granted an extension of ten years for the continued operation of the reactor. It was damaged during the 2011 Tōhoku earthquake and tsunami.

20,000 yearsMore than 30 years on, scientists estimate the zone around the former plant will not be habitable for up to 20,000 years. The disaster took place near the city of Chernobyl in the former USSR, which invested heavily in nuclear power after World War II.

How is Fukushima being cleaned up?

On 10 April 2011, TEPCO began using remote-controlled, unmanned heavy equipment to remove debris from around reactors 1–4. The debris and rubble, caused by hydrogen explosions at reactors 1 and 3, was impeding recovery operations both by being in the way and emitting high radioactivity.

Could Chernobyl Happen Again?

The flow of electricity stops. I do believe our best minds can ensure such designs in the world’s nuclear power plants. If we can ensure that all nuclear power plants in the world are fail-safe designs, then we can indeed say that even though failures could happen, “No, another Chernobyl is simply impossible.”
