12 years after the Fukushima Daiichi Nuclear Power Plant accident, modifications in nuclear energy coverage and challenges[Details]| NHK

At the Tokyo Electric Power Company Fukushima Daiichi Nuclear Power Station, which brought on the worst accident in historical past, investigations and preparations are underway to take away the melted “nuclear fuel debris”, whereas development work to launch the handled water that continues to build up has been accomplished. is approaching.

On March 11, 2011, at TEPCO’s Fukushima Daiichi Nuclear Power Station, Units 1 to three of the six reactors had been in operation, whereas the remaining three reactors had been shut down for periodic inspections.

Around 2:46 pm, an enormous earthquake with a magnitude of 9.0 occurred off the Tohoku coast.

All three working reactors had been shut down.

Due to the results of the earthquake, transmission towers collapsed, which minimize off the provision of electrical energy from the surface, and the emergency turbines began up. The constructing containing such gadgets was flooded.

All energy wanted to chill the nuclear gasoline has been misplaced.

A couple of hours later, it’s believed {that a} meltdown occurred at Unit 1, the place the nuclear gasoline melted away, and round 3:30 p.m. An explosion occurred.

Furthermore, meltdowns occurred in Units 3 and a couple of one after one other.

In Unit 3, a hydrogen explosion occurred shortly after 11:00 a.m. on March 14, and in Unit 2, though a hydrogen explosion didn’t happen, there’s a chance that the containment vessel was severely broken. A considerable amount of radioactive materials is believed to have been launched exterior.

In addition, Unit 4, which had been stopped, exploded shortly after 6:00 a.m. on the fifteenth resulting from hydrogen flowing from the exhaust pipe related to Unit 3.

According to the worldwide requirements that point out the seriousness of the accident, it’s the most critical “Level 7”.

It was the worst accident in historical past, together with the 1986 accident on the former Soviet Union’s Chernobyl nuclear energy plant in present-day Ukraine.
