The base of the pressure vessel of the 1st reactor at the Fukushima nuclear power plant has been found destroyed. This photo shows the melted out concrete and the naked metal structure due to the nuclear fuel melting through the base of the vessel. They say it has never been directly observed nor taken for a photo before.
It proves that the fuel has really melted through the base of pressure vessel. It has melted the base structure made of reinforced concrete. Only the iron bars are left while the concrete is completely disappeared.
Without the base structure, the pressure vessel, which weighs 400 tons, could easily fall down and destroy the containment vessel with the result that the massive radioactive substances are scattered into the air. There have been earth quakes occurring possibly as the aftermaths of the big earth quake in 2011. They could unstabilize and render the pressure vessel fallen down.
The melted fuel could cause contamination of the underground water pouring into the reactor. The inflowing water is told up to the amount of 150 tons in a day. They are starting marine disposal of the "ALPS treated" water, which still contains tritium and probably small amount of the other nuclear materials. The newly produced contaminated water due to underground water surpasses the disposed treated water in amount. It means the marine disposal should continue almost eternally. We know little about the result of such disposal into the ocean yet. It is clear that disposed radioactive materials won't be retrieved even if there is any serious issue happening from its contamination.
A couple of years ago, as the roadmap to decommissioning of the Fukushima nuclear power plant says, they could have reached the melted through nuclear fuel and have started discharging it out. They could never even reached it yet. Only taking photos like this around the area in the reactor.
Our government designated the nuclear power as the base load. And they would restart some nuclear power plants beyond their time limit of running planned at construction and even construct new plants. The power necessity for the country already became less than the power generation capacity mainly because of the decrease of the population.
Without elucidation of the real cause of the serious accident at Fukushima nuclear power plant, they could bring on a disaster with another nuclear power plant in the near future. Honestly, there were discussions or proposals by researchers in seismology and science of disaster prevention alarming the nuclear power plant accident with an earthquake/tsunami at Fukushima after the big earthquake in Kobe in 1995. However, the power companies and the politicians/beaurocrats/researchers affiliated with them have postponed it or shut down before it was on the table of politics. This affiliated group of politics/business/administration is called as the Nuclear Power Village in our country. They are chasing only their own interest or concession neglecting possible further disaster.
