The better question is why? Why are the accumulating so much contaminated water at Fukushima?

If they can't pour it down the drain (into the ocean) or evaporate it, what else can they do but accumulate it?

They can't just stop using the water - they need it to keep the dangerous radioactive materials covered and cooled. Plus some of the water is ground water that is contaminated and they are currently trying to stop that contaminated water reaching the sea.

Exactly

It’s the radiation leaking into the ground they have been collecting, to stop it from reaching the ocean


The irony is not lost

There are multiple reactors that have in effect breached containment, with the water soluble isotopes flowing into the environment

Which isn’t going to stop in anyone’s lifetime


Not surprising that Japan is now trying to make safe all of the other reactors

The problem is the same one every country has

There is no way to actually make it safe

But at least the reactors won’t be running when the next disaster happens

The two biggest fuck up involving reactors are becoming impossible to ignore

The first is obviously the spent fuel rods


The second is no design was ever actually tested to see if it would work to contain the fuel in a worst case scenario

(they didn’t)

Oh sure you can say the fuel is still inside the containment, but if it’s leaking radioactive elements of the fuel into the groundwater and ocean, is it really contained?

“Well most of its still somewhere inside, so there is that.”

Yeah, but there is also the next 250,000 years to worry about.

Japan puts off decision to release treated Fukushima water into sea

Japan has put off a decision to release treated radioactive water from the crippled Fukushima nuclear plant into the sea, government sources have said, after reports of a formal decision later this month triggered strong opposition from fishermen.

Economy, Trade and Industry Minister Hiroshi Kajiyama told a news conference Friday the government has no plan to announce a decision on what to do with over 1.2 million tons of treated water as reported.

His remarks came after government sources said last week it would decide on the release of the water on Tuesday. Prime Minister Yoshihide Suga said last month, during a visit to the Fukushima No. 1 nuclear power plant which suffered meltdowns following the March 2011 earthquake and tsunami, that the government wants “to make a decision as soon as possible” on how to deal with the water.

“We are not at a stage where we can announce the specific timing of a decision” on how to deal with the stored water, Kajiyama said, adding, “We want to proceed with the matter carefully.”

The water used to cool the damaged reactors has been treated using an advanced liquid processing system (ALPS) to remove all radioactive material apart from tritium and is stored in tanks on the plant’s premises.

The Fukushima complex is expected to run out of water storage capacity by the summer of 2022, with contaminated water increasing by about 170 tons per day.

One might ask why tritium is still being produced in such quantities

Fukushima nuclear debris removal delayed by virus

The removal of nuclear debris from Japan's crippled Fukushima power plant will be delayed by about a year, because the pandemic has set back development of specialised equipment, the plant's operator said Thursday.

The Tokyo Electric Power Co (TEPCO) had been scheduled to start removing melted fuel from deep inside one of the mangled reactors next year, a decade after the nation's worst ever nuclear crisis was triggered by a tsunami.

The process is considered the most difficult of the massive decommissioning programme, which is expected to take three to four decades to complete.

TEPCO had planned to develop a robot arm in Britain that would have arrived in Japan next year to start work -- but chief decommissioning officer Akira Ono told a news conference that a recent spike in Covid-19 infections in the UK had delayed this.

"It will now be difficult to transfer the system in January as scheduled," Ono said, adding he hoped the delay would be limited to a year.

The removal process is expected to take several years for the number two unit, which is estimated to contain some 237 tonnes of debris, Kyodo News said.

Altogether, three melted-down units are estimated to house around 880 tonnes of debris.

At least they have a choice:. Death from the 'rona bug or radiation.

In light of the virus, Fukutooshima looks like a cake walk.
You can lead them to knowledge, but you can't make them think.

Dumping the tritium into the ocean isn't a worst case scenario, and obviously it will happen. Probably in some disastrous fashion, as it is the most common form of nuclear pollution. Rather than a trickle, allowing the carcinogenic radioactive water molecules to disperse and mix, there will be some huge dump and massive failure of the ever increasing storage tanks.

None of that is even a speed bump on the real disaster, which will not be cleaned up, not in your lifetime, and not in your grandchildren's lifetime. The windscale disaster, over 63 years ago, was a minor disaster compared to Fukushima. Just one small reactor, which sits in the midst of an advanced undamaged facility, with the entire resources of England to deal with the relatively small amount of melted or damaged fuel, still in the reactor, contained. Sealed up, not leaking into the ground water and ocean all the time. (like Fukushima is doing)

63 years it has been sitting there, and the "plan" to "clean it up" is theorized to take another 100 years. No, that is not a joke. Since 1984 they have been trying to remove the filter galleries, which prevented most of the radioactive material from blanketing north easter England, and of course Europe.

After that they will demolish the entire 125 metre tall ventilation chimney, a highly radioactive problem, which might take a while. It took 4 years to remove the first block of radioactive concrete, but in the following year they removed 9 metres, each metre creates 100 tons of radioactive concrete and steel to deal with, which means bagging it up and laying it nearby, where it must be protected, watched, guarded and kept safe for the next 140,000 years. Give or take a 50,000 years.

Plans on what to do with the melted fuel inside the reactor do not exist. Just as none exist for what to do about Fukushima. The Windscale reactor has an estimated 15 tonnes of fuel sealed inside of it. And sometime in the next 100 years they plan on doing something about it.

Fukushima has maybe 400 tons of melted fuel, not inside a reactor, and an estimated 10,000/30,000 tons of spent fuel rods next to the ruined reactors. These sort of facts are unpleasant for the nuclear cheerleaders, who live in a fantasy world where nuclear is both cheap and safe. It is not cheap, and it has never been safe.
