Fukushima: Still Simmering

September 11, 2019


TOKYO (Reuters) – Japan’s Tokyo Electric Power (9501.T) will have to dump radioactive water from its destroyed Fukushima nuclear power plant into the Pacific Ocean as it runs out of room to store it, the environment minister said on Tuesday.
Tokyo Electric, or Tepco, has collected more than 1 million tonnes of contaminated water from the cooling pipes used to keep fuel cores from melting since the plant was crippled by an earthquake and tsunami in 2011. 
“The only option will be to drain it into the sea and dilute it,” the minister, Yoshiaki Harada, told a news briefing in Tokyo. 
“The whole of the government will discuss this, but I would like to offer my simple opinion.” 
The government is awaiting a report from an expert panel before making a final decision on how to dispose of the radioactive water. 
Japan’s Chief Cabinet Secretary Yoshihide Suga, in a separate press briefing, described Harada’s comments as “his personal opinion”.
Tepco was not in a position to decide what to do but would follow the policy once the government made a decision, a spokesman for the utility said. 
The utility says it will run out of room to store the water by 2022. Harada did not say how much water would need to be dumped into the ocean. 
Any green light from the government to dump the waste into the sea would anger neighbors such as South Korea, which summoned a senior Japanese embassy official last month to explain how the Fukushima water would be dealt with. 

“We’re just hoping to hear more details of the discussions that are under way in Tokyo so that there won’t be a surprise announcement,” a South Korean diplomat told Reuters, requesting anonymity due to the sensitivity of bilateral ties. 
South Korea’s foreign ministry said in a statement said it had asked Japan “to take a wise and prudent decision on the issue”. 
Relations between the East Asian nations are already frosty following a dispute over compensation for Koreans forced to work in Japanese factories in World War Two.
Coastal nuclear plants commonly dump into the ocean water that contains tritium, an isotope of hydrogen that is hard to separate and is considered to be relatively harmless. 
Tepco, which also faces opposition from fishermen, admitted last year that the water in its tanks still contained contaminants beside tritium. 
“The government must commit to the only environmentally acceptable option for managing this water crisis which is long term storage and processing to remove radioactivity, including tritium,” Shaun Burnie, senior nuclear specialist with Greenpeace Germany, said in an email.

    Condense the water with “free” energy from the plant, releasing the water vapor safely, and consolidating the amount of storage space?

      The tritium in the storage tanks is chemically indistinguishable from ordinary water, you can’t just boil off the H2O from the HTO. Also, the reactors are no longer producing any usable amount of heat. Fission stopped half an hour before the tsunami hit, and the residual radiation has been declining asymptotically since then. After eight years, fuel would normally be cool enough to take out of the spent fuel pool and put into dry storage.

    I’m not following why they couldn’t have cycled the same water around the core but I’m not going to spend time researching that. I’m assuming there’s some technical reason.

  3. redskylite Says:

    And news from Russia, they claim “World’s first floating nuclear reactor arrives in Pevek after 4,700 km voyage on Northern Sea Route”.

    The good news is that it will be replacing a coal powered power station. The bad news is that it is to be used by the oil industry.

    Hope it remains intact for it’s expected 12 years of operation.
    , and we don’t add further pollution to our oceans.
