Coolant water leakage accelerated in reactor 3 Fukushima plant

Tepco was forced to restart the coolant water injection to the crippled reactor 3 of the Fukushima nuclear plant.

On the 14th of June, 2022, Tepco began halting coolant water injection to reactor 3 as an experiment. It was originally designed to continue for three months until the 12th of September, 2022 in order to observe the transition of the temperature and the radiation level. However, water level decreased faster than the estimate and Tepco was forced to restart the water injection only in five days, the 19th of June. The further decrease of the water level makes it impossible to collect data.

In the previous experiment implemented in April, 2021, Tepco halted water injection for one week but the water level decreased by only 50cm. Since the earthquake hit the Fukushima nuclear plant this March, the water level has been continuously decreasing for unknown reasons.

About this site

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.
