Molten fuel might be out of concrete base to directly damage primary containment vessel of Reactor 1

Molten fuel might be already outside of the concrete base and damaging the vulnerable part of PCV (Primary Containment Vessel) in Reactor 1.
On 9/10/2014, IRID (International Research Institute for Nuclear Decommissioning) announced it in the meeting of Atomic Energy Society of Japan.
They have admitted the fuel has melted through RPV (Reactor Pressure Vessel) and dropped onto the concrete part inside of PCV, which is called “melt through”. However they haven’t stated the molten fuel has directly touched the wall of PCV to be potentially exposed to the environment.
In this latest report, IRID admitted the possibility that the molten fuel reached where the concrete base is not protecting the vulnerable pipes and directly damaging PCV.
They commented Reactor 2 and 3 are less likely to be in the same situation, but didn’t deny the possibility.

Iori Mochizuki I tried to install a Bitcoin button on the sidebar. Because I don’t have bitcoin, I can’t test it to see if it works. I would be very glad if you use it for a test.The post Molten fuel might be out of concrete base to directly damage primary containment vessel of Reactor 1 appeared first on Fukushima Diary.
