You can go to ground.news/scishow or click the link in the description to get 30% off the Vantage level subscription. In 2011, a catastrophic earthquake hit Japan and damaged the Fukushima Daiichi nuclear power plant.
Not to the point that it stopped working. Just enough that they needed to get a backup power supply involved. The backup power kept things running smoothly for a hot minute.
But less than an hour later, a tsunami triggered by the earthquake came in and broke the backup generators. At that point, the plant couldn’t keep its nuclear fuel cool, and three of its reactors melted. It was the end for those reactors, but just the beginning of a monumental nuclear waste disaster that was rated right up there with Chernobyl as one of the worst the world has ever seen.
And we’re still dealing with the radioactive material that resulted from the event. More than a decade later, responders continue to roll out new interventions to minimize global contamination. Like, this year they started dumping some of the nuclear wastewater into the ocean on purpose. Which begs the question: Is that okay? [♪ INTRO] When a tsunami hits a power plant after an earthquake has already weakened its defenses, there are a few emergencies to deal with.
But one of the biggest is water overflow. Water from the giant wave ran into Fukushima’s nuclear reactors, into the plant buildings, and into the trenches where pipes run. It was just kind of everywhere.
Nuclear power plants also run cold water through the reactors during normal operation to keep them from overheating and to absorb energy in the event of an accident. Those reactors are the part of the power plant that generate electricity using rods of uranium oxide to boil water and turn steam turbines. They’re also where the radioactivity comes from.
When the reactors melted, all of the water in that area became radioactive. The plant had storage tanks where water that was supposed to be there was treated. But the tsunami basically flooded the plant, which meant it didn’t have enough space to store all of the extra contaminated water.
That meant that one way or another, some of it needed to leave. Authorities decided to release the water that they knew was less contaminated first to make room to store the more dangerous stuff, so ultimately dumping 10,000 tons of wastewater into the sea. I know it doesn’t sound great, but reports from the Nuclear and Industrial Safety Agency suggested that radioactivity levels in the ocean didn’t significantly change after the dump.
So, all things considered, it wasn’t the worst choice they could have made. But that wasn’t the only contaminated water coming from this plant. It was also leaking.
And I’m not talking about a tiny crack you can put a piece of duct tape over. The plant leaked about 60% of its contents into the ground, which then mixed with nearby groundwater. Within a few months, the company that operates the power plant built underground walls around the entire property to keep the seepage contained.
Then, a freezing underground wall was constructed around the plant buildings to prevent water from flowing back into the reactors. Water expands when it’s frozen, so by freezing the water in the soil, the ground became more solid and less passable. Once responders stopped the worst of the leakage, they needed to remove the worst of the toxins in the water.
By “toxins,” here, I mean the isotopes of elements that decayed from the original uranium oxide fuel, like caesium-134. Those isotopes can release energy in the form of radioactivity for years. They’re also referred to as radionuclides.
If those radionuclides have enough energy, they can break the bonds between molecules in your body, including your DNA. That’s the kind of thing that makes radiation harmful to us and a potential source of cancer. So, to get rid of those radionuclides, Japan started treating the wastewater with a method called the Advanced Liquid Processing System.
Basically, the radionuclides were captured in a filter so that only water and tritium could pass through. Now, we want the water to clear through the system, but that other stuff? Tritium?
It sounds like the kind of thing that could take down Superman. Well the good news is tritium isn’t as scary as it sounds. It’s a naturally occurring form of hydrogen with two neutrons.
It comes from the clash of cosmic rays hitting air molecules in our atmosphere. So it’s all over the place. And, really, it’s only a radiation hazard in very large quantities.
While there are things we can do to reduce the amount of tritium, it’s the least dangerous of the contaminants in Fukushima’s water. So once responders figured out how to treat the contaminated water, they had pretty much solved all of the plant’s problems, right? Well… You know how there wasn’t enough space to store all of the water after the tsunami hit and they needed to dump a bunch of it?
Well, the tanks kind of refilled. See, when the disaster hit, an explosion literally blew the roof off. And the debris from that explosion was radioactive.
So any rain that fell in the area and came into contact with that debris became contaminated as well. Not to mention, before the frozen underground walls were erected, groundwater flowed into containment tanks sitting near the reactors. So water had been building up inside the plant for years.
And all that time, water was getting pumped into the system to keep it cool. Eventually, there wasn’t anywhere left to put it. Estimates suggested that if the plant’s operators did nothing, the tanks would be full by 2024.
Faced with another tough decision, they began to release treated water into the Pacific Ocean in 2023. If this sounds awful, you should know that it’s the same thing other nuclear power plants do with their wastewater once it has been treated, as well. And the world wasn’t just taking it for granted that the water was safe to dump.
Switzerland, France, the US, South Korea, Austria, and Monaco conducted an international study. They gathered samples of the treated water at the plant and the seawater near the release site. Using those samples and machines like gamma-ray spectrometers, each lab tallied up the amount of radionuclides they could find to see how dangerous the water was.
A gamma-ray spectrometer is a tool that shows scientists the spectrum of gamma ray energy coming off of whatever material they feed into the machine. Since different elements give off different amounts of gamma ray energy, scientists can figure out which ones they’re looking at from the readouts. After measuring the amount of each radionuclide independently, the labs found less than 1% of the regulatory limit for any of these dangerous molecules.
And they’re going to continue sampling and testing the wastewater as it’s released. So if the amount of detectable radionuclides starts to rise to concerning levels, they’ll need a new approach. Some nearby countries, including China and South Korea, still aren’t sure that enough is being done to protect the animals that live in those waters.
They’ve even gone so far as to ban seafood imports from Japan. And I get the concern. Just after the 2011 disaster, 53% of fish caught near the plant were high in radionuclides like caesium-134.
But by 2014, that number dropped to 0.6%. Which is more than nothing, but a huge improvement. So if we’re at a point where the fish are less contaminated and the water is less toxic based on international assessments, it’s time to start thinking about the future of the Fukushima Daiichi plant.
Right now, the plan is to seal off the damaged units for another decade or two to let more of the radionuclides decay away, and then demolish the remains. And we’re left with water that’s being released into the ocean that isn’t completely free of toxins, but way below accepted limits of contamination. So dumping water that spent years mingling with radioactive debris might seem like a scary prospect. But scientists across the world say that, thanks to treatment, it probably is okay.
