“Guess what? TEPCO going to spend half a billion to clean up the water. Doesn’t say how, if it has been done before, or anything like that……they want the Olympics.
Unbelievable that none of the executives of TEPCO have faced any charges for this world disaster……..”
– Japan earmarks £300m+ for Fukushima cleanup (Guardian, Sep 3, 2013):
Tokyo unveils measures to decontaminate toxic water at nuclear power plant as Tepco struggles to prevent leaks into Pacific
Japan’s government is to spend almost $500m (£320m) in an attempt to contain leaks and decontaminate highly toxic water at the Fukushima Daiichi nuclear power plant.
The measures, announced on Tuesday, come as the plant’s operator, Tokyo Electric Power (Tepco), struggles to prevent leaks into the Pacific Ocean and to find a way to contain and treat the huge volume of water that has accumulated at the site since it was hit by a tsunami in March 2011.
The decision is widely seen as a safety appeal just days before the International Olympic Committee chooses between Tokyo, Istanbul and Madrid on which city will host the 2020 Olympics.
The prime minister, Shinzo Abe, said the government would take a more active role in the biggest nuclear cleanup in history, amid mounting concern that Tepco is no longer able to cope alone.
“The world is watching to see if we can carry out the decommissioning of the Fukushima nuclear power plant, including addressing the contaminated water issues,” Abe reportedly told cabinet ministers.
Reports said that about 32bn yen of the 47bn yen in new funding would be spent on constructing a 1.4km-long underground frozen wall around four damaged reactors – an untested and expensive technique. The wall would prevent groundwater from mixing with coolant water that becomes contaminated after it comes into contact with melted nuclear fuel.
A further 15bn yen will be spent on improving technology to remove all radioactive particles – except tritium – from the water, or to least reduce them to legally accepted levels.
The head of Japan’s nuclear watchdog, Shunichi Tanaka, confirmed on Monday that discharging treated water into the ocean is one option under consideration.
Given the large volumes involved, experts say that Tepco will soon run out of storage space and will have no choice than to discharge or evaporate the contaminated water.
Last month, Tepco belatedly confirmed reports that coolant water was mixing with groundwater and flowing into the sea at a rate of about 300 tons a day.
In a separate incident, the utility, which was effectively nationalised last year when it was saved from collapse with a 1tn yen injection of public funds, said a storage tank had sprung a serious leak. Smaller amounts of tainted water are thought to have breached other tanks and pipes.
Last weekend, workers recorded radiation levels of up to 1,800 millisieverts an hour near one tank. A radiation dose of that size is big enough to kill an unprotected person nearby in about four hours. Tepco said the radiation was emitted in the form of beta rays – which travel only short distances and can be easily shut out – and that workers had not been put at risk.
The new funding was announced days before the International Olympic Committee [IOC] is due to select the host city for the 2020 Olympics. Concern is growing that the water crisis could harm Tokyo’s chances of being chosen ahead of Madrid and Istanbul.
But Japanese Olympic officials said the Fukushima crisis should not affect Tokyo’s prospects. “There is no risk from Fukushima,” Tsunekazu Takeda, who is leading the city’s bid, told AFP. “Day-to-day life in Tokyo carries on as normal for its 35 million people.
“The air and water quality is safe. Also the data shows that the radiation level is the same as most cities, like Paris, London and New York. Our main focus is to deliver a great and safe Games.”
Abe will deliver Japan’s final pitch to the IOC ahead of the decision in Buenos Aires on Saturday evening.
The emergency measures announced on Tuesday do not address the wider problem created by the need to constantly cool the damaged reactors and the resulting buildup of contaminated water. In addition, the new funding represents only a tiny potion of the tens of billions of dollars experts estimate it will cost to decommission the plant, an operation that is likely to last at least 40 years.
No decision has been taken on who will foot the bill – the state or Tepco.
“This is a matter of public safety, so the country has to take the lead on this issue and respond as quickly as possible. Figuring out who to bill for the costs can come later,” Akira Amari, the economics minister, told reporters.
Public criticism of Tepco has intensified in recent months. It initially denied reports of groundwater leaks, and was found to have employed just two workers to conduct twice-daily inspections of more than 1,000 storage tanks containing an estimated 330,000 tons of contaminated water.
To compound Tepco’s problems, sources familiar with the situation at the plant say the firm is struggling to hire new workers, as others resign or are forced to leave because they have reached their radiation exposure threshold.
Critics of the nuclear industry, even inside the governing Liberal Democratic party, are beginning to ask why no Tepco executives have been held accountable for the latest string of accidents.
“Is anyone at Tepco taking responsibility for these mistakes?” Reuters quoted Taro Kono, an LDP deputy secretary general, as saying. “I haven’t heard of anyone stepping down or being fired. Tepco needs to go down and the government needs to take over.”
Senior LDP officials have said that liquidating Tepco is not under consideration.
