Record radiation found in fish near Fukushima nuclear plant..Rat may have caused Fukushima outage
A record quantity of radioactive cesium – 7,400 times the country’s limit deemed safe for human consumption – has been detected in a greenling fish in the waters near the crippled Fukushima plant, two years after the nuclear disaster.
Tokyo Electric Power Co (TEPCO), which runs the Fukushima Daiichi Nuclear Power Station, discovered a record 740,000 becquerels per kilogram of radioactive cesium in the fish, Kyodo News reported.
The operator installed a net on the seafloor of the port exit near the plant to prevent the fish from escaping.
The bottom-dwelling greenling fish was found in a cage set up by TEPCO inside the port next to the Fukushima Daiichi plant, a utility official told AP on condition of anonymity.
The company also indicated that the previous record of cesium concentration in fish was 510,000 becquerels per kilogram detected in another greenling caught in the same area, TEPCO said.
In January, a fish containing over 2,500 times Japan’s legal limit for radiation in seafood was caught in the vicinity of the nuclear plant, the facility’s operator reported.
The March 11, 2011, earthquake and tsunami damaged the plant, causing meltdowns that spewed radiation into the surrounding soil and water. The disaster forced the evacuation of 170,000 local residents.
Some experts have speculated that radioactive water may be seeping from the plant into the ocean; this may have been confirmed after bluefin tuna caught off the coast of California tested positive forradiation poisoning at the end of February.
Most fish along the Fukushima coast are banned from market.
THE power outage at Japan’s troubled Fukushima power station may have been caused by a rat.
Masayuki Ono, spokesman for Tokyo Electric Power Co., the utility that runs the Fukushima Dai-ichi plant, says a 15-centimetre rat was found dead Wednesday near a switchboard.
He says the rat may be linked to the power failure, but that more investigation is needed to be sure.
Technicians have restored power to all cooling systems at the reactors after a blackout sparked a new crisis.
Equipment in pools used to cool used fuel are now fully operational, some 30 hours after the blackout, Tokyo Electric Power Co (TEPCO) said.
Used nuclear fuel becomes dangerous if its temperature is allowed to rise uncontrollably to the point where a self-sustaining critical reaction begins, causing a meltdown.
“We have deeply worried the public, but the system has been restored and we have been able to stably cool” the pools, TEPCO spokesman Mr Ono told a press conference.
The utility was yet to find out what caused the power outage, but suspected a problem with a switchboard. “It will require some time because of detailed analysis required,” Mr Ono added.
The incident was a reminder of the vulnerable state of the Fukushima plant two years after the tsunami which sparked the meltdowns, despite the government’s claim that the reactors are in a “cold shutdown” state and no longer releasing high levels of radiation.
yes fukushima hasnt gone away..its still radiating anything and everything near it..and slowly contaminating the pacific..its thats horrendous..and look how unstable it all is..a fucking rat can cause the 4 cooling pools to break down!..this is beyond a joke..its criminal..and its deadly..
