TOKYO (majirox news) – TEPCO (Tokyo Electric Co and plant operator) will empty the outside suppression surge tank, which contains low-level radioactive water, and let the water flow into the sea. The low-level contaminated water is being released into the sea to make room for highly contaminated water from reactor No. 2 from the Fukushima Dai-ichi power plant.
TEPCO started releasing about 11,500 tons of the water on Monday evening from the surge tank, which is connected to reactor No. 2.
At 9 p.m. reactors No. 5 and 6 started emptying its suppression surge tanks.
Radioactive water was 100,000 times the normal level found in reactor No. 2 in the turbine building. This stopped efforts to cool the damaged reactors.
Yukio Edano, a top government spokesman, says the government approved the operation plan as an “urgent matter.” He added the operation was an emergency measure to ensure the safety of the plant. The government told TEPCO to monitor the radioactivity in the seawater and closely track the environmental impact.
TEPCO said today if people ate fish and seaweed caught near the plant every day for a year, their radiation exposure would be 0.6 millisievert.
Fishermen angry — Update
The local fisherman are angry. “We want TEPCO and the government to guarantee us,” said one fisherman.
According to Japan’s Ministry of Agriculture, Forestry and Fisheries of Japan, 111 fishing ports in Iwate, 142 in Miyagi and 10 ports in Fukushima prefectures are in ruins and there is considerable damage in parts of Aomori. There isn’t going to be any fishing fleet going out this year, particularly as so many of the boats are sunk and many harbors clogged with debris.
However, a few fishermen and ports survived the devastation. A few fisherman from the coast of Ibaraki prefecture went out on April 5 and caught some fish. But when they tried to sell the fish at Choshi Harbor in Chiba, the market refused to purchase the fish as its safety has not been confirmed.
Radioactive water still pouring into the sea
Chemicals, sawdust and shredded newspapers failed to stop the radioactive water leaking into the sea through a 20-centimeter crack in the pit near the sluice gate of reactor No. 2 at the Fukushima Dai-ichi nuclear power plant, said TEPCO (Tokyo Electric Co and plant operator). It is still unknown how much radioactive water is escaping through the crack.
Workers first filled the pit with concrete cement to seal the leak, but it failed. The pit is for maintenance and storing electric cables.
As of yesterday, workers sprayed about 9,300 tons of water into reactor No. 2 to cool the temperatures of the spent fuel rods pool and reactor. The total amount of water in reactors No. 1, 2 and 3 is about 30,000 tons. The plant has been spewing radioactivity since the earthquake and tsunami struck Japan on March 11.
At a news conference this morning, Yukio Edano, top government official, said, “We have asked TEPCO (Tokyo Electric Co and plant owner) to find out where the water in the pit is coming from. We will try to plug the leaking from that place, too.”
Giant silt curt will be built
Edano asked TEPCO to build a giant silt curt in the ocean to stop the spread of more contamination from the Fukushima plant.
