Tepco is planning the first endoscope operation to reactor1 announced in the daily press conference on 5/28/2012.
They are starting to prepare it by mid August, and finishing the operation from the end of August to September.
The endoscope will be inserted from the through hole “X-100B”, located on the first floor.
Because it’s 4.5m high from the floor, they will build a trestle to operate.
The purpose is to check the atmospheric temperature, dose, temperature of water and the water level.
They also plan to take the sample of water inside of the PCV.
However, they will not be able to see the nuclear fuel directly because it’s outside of the pedestal. Tepco assumes the melted fuel is inside of the pedestal.
Tepco also assumes, the nuclear fuel is “cold” to remain in the PCV. It has been in coolant water for longer than one year, water‐soluble nuclide might be captured in the sampling water.
However, they admit it’s just their assumption that the nuclear fuel remains within pedestal. Still it’s not known where/how the fuel is.
This website updates the latest news about the Fukushima nuclear plant and also archives the past news from 2011. Because it's always updated and added live, articles, categories and the tags are not necessarily fitted in the latest format.
I am the writer of this website. About page remains in 2014. This is because my memory about 311 was clearer than now, 2023, and I think it can have a historical value. Now I'm living in Romania with 3 cats as an independent data scientist.
Actually, nothing has progressed in the plant since 2011. We still don't even know what is going on inside. They must keep cooling the crippled reactors by water, but additionally groundwater keeps flowing into the reactor buildings from the broken parts. This is why highly contaminated water is always produced more than it can circulate. Tepco is planning to officially discharge this water to the Pacific but Tritium is still remaining in it. They dilute this with seawater so that it is legally safe, but scientifically the same amount of radioactive tritium is contained. They say it is safe to discharge, but none of them have drunk it.
