Japan Marine Expert:
“TEPCO can no longer effectively clean, filter and store the massive amounts of radioactive water on its site. At some point in the near future — and this may have happened already — the utility will simply resort to emptying its radioactive tanks into the Pacific Ocean,” [Shoji Tsurumi, an expert from Japan’s Marine Science & Technology Institute] said. “They will simply run out of other options to store such huge quantities of water.” “Perhaps this is another reason the government is keeping its distance. After all, if the government were to take responsibility for dumping toxic water into the ocean, who would it have to blame when the global backlash came?” Tsurumi said.
Spiegel Online, Sept. 10, 2013: As for the contents of the 1,000 radioactive storage tanks, there is only one long-term solution — the contaminated water must be cleaned, and then emptied into the ocean. It is possible to a large extent to filter out the cesium and strontium. The tritium, although somewhat less of a concern, can’t be filtered out. Little by little, the Japanese public is being prepared for the coming release of this water — much to the horror of fishermen.
New Scientist: Dump all Fukushima nuclear waste in Pacific, no risk to U.S. — “They have to make people understand low levels of radiation don’t matter” — “None of this is going to do anything health wise”
Should Fukushima’s radioactive water be dumped at sea? […]
On an international level, even if all the waste from Fukushima was dumped neat into the Pacific, dilution would eliminate any radiation risks to distant countries like the US, says Simon Boxall of the National Oceanography Centre in Southampton, UK.
The ocean would be the safest place for the waste water, says Geraldine Thomas, who runs the Chernobyl Tissue Bank at Imperial College London. “But to make that politically acceptable they have to talk to the local population. They have to make people understand that low levels of radiation don’t matter because we’re all exposed to it all the time.”
In other words, it is more of a communication problem than a public health problem. “None of this is going to do anything health wise,” she says. “Fukushima is nothing compared to Chernobyl.” [See Buesseler link below]
[…] “Anything they can do to remove the more dangerous compounds and dilute the others [before dumping] is almost the only solution,” says Ken Buesseler of Woods Hole Oceanographic Institution in Massachusetts.
Nuclear Expert: Water now at Fukushima plant has 3 times more cesium than Chernobyl’s total release — “That underscores the scale of this never-ending threat”
Experts say the government’s admission shows that the crisis at the Daiichi complex is being managed, not solved.
“It is an emergency – has been since 11 March 2011 and will continue to be long into the future,” said Shaun Burnie, an independent nuclear consultant.
He says onsite contaminated water contains three times the caesium released from the 1986 Chernobyl accident – the world’s worst nuclear disaster.
“That underscores the scale of this never-ending threat.”
