Fukushima Daiichi Nuclear Power Plant Leaks at 3 places on frozen ground wall Leakage to replace parts, etc. January 17 5:39
It turned out that the coolant on the frozen soil wall created to reduce the generation of contaminated water at the Fukushima Daiichi Nuclear Power Plant was leaking at three places, and TEPCO will take measures such as replacing parts. Was.
The permafrost wall has been in operation four years ago to reduce the generation of contaminated water by freezing the ground around the building at the Fukushima Daiichi Nuclear Power Plant and preventing inflow of groundwater.
Coolant is flowing inside the frozen pipe buried in the ground, but this month TEPCO investigated that there is a possibility that it has leaked because the water level of the tank storing the coolant has dropped below normal. I was
As a result, coolant leaks were found in some of the components connecting the freeze tubes. There are a total of three leaks, and we will replace all parts.
The amount of coolant leaked is estimated to be 20,000 liters out of 1.1 million liters, which means that the operation of frozen soil walls will not be affected.
A leak from the freezing tube was found in one place last month, and this time we will repair it together.
