An undersea tunnel to Japan to discharge radioactively contaminated water from the Fukushima nuclear power plant into the ocean is nearing completion.
In addition, rockfish caught in the harbor of the Fukushima nuclear power plant were found to contain 180 times the standard level of cesium.
According to Kyodo News and Fukushima TV on the 6th, TEPCO recently completed the excavation of an undersea tunnel and announced that it had completed internal cleaning and an inspection by the Nuclear Regulatory Commission the previous day.
As a result, the work of filling a submarine tunnel with seawater to release radioactively contaminated water into the sea began.
The Japanese government and TEPCO plan to complete construction of the undersea tunnel at the end of this month and release the contaminated water into the ocean from the summer.
Meanwhile, TEPCO announced that it had tested rockfish caught last month at the port of the Fukushima Nuclear Power Plant and found 18,000 becquerels of radioactive cesium, which is 180 times the standard value (100 becquerels (Bq) per 1kg) set by Japan Food. Sanitation Law.
Cesium of 1,200 becquerels was also found in the mouse tuna caught in the same place in April.
Kyodo News reported that the place where the fish was caught was the breakwater on the seaward side of nuclear power plants Units 1 to 4, and “internal water with a relatively high concentration of radioactive substances is flowing out.”
Accordingly, TEPCO said it is taking countermeasures such as installing nets to prevent fish from escaping the port.
