Edit: spelling of tritium
Exactly. And if the quantities Japan are talking about are correct (860 TBq / trillion becquerels), this is a huge fuss about nothing. France's La Hague nuclear reprocessing facility discharges many times more tritium than that into the English Channel every single year as part of it's normal operations!

> In addition to high levels of hazardous radionuclides such as strontium-90, TEPCO on 27 August 2020 acknowledged for the first time the presence of high levels of carbon-14 in the contaminated tank water
This is a complete non-issue.
You don't dive into this in a single sentence, but I do want to raise the point that fossil fuels, while they are bad are better than the alternatives for many countries, especially developing ones. Let's consider some alternatives.
Wood and animal waste: for developing nations that need any energy they can get, they will burn these 2, which are massively worse than fossil fuels, and no where near as energy dense.
Coal: massive step up from the above. Yes it burns dirty, but there are capture methods to make coal cleaner.
Natural gas: one of the best out there. Low emissions and again, energy dense. Turned into LNG, it's easy to transport and use elsewhere.
Nothing... This is the point that I think lots of people miss. Having access to energy dense materials like coal or LNG are a major factor in bring developing nation people out of poverty. Not having these "dirty" energy sources that kill some is way worse than not having it at all (more people will die without the energy).
People need to be reasonable and realize that rich nations can go nuclear and renewable, but we still need to allow developing nations to have access to the others, even encourage it. That means first world nations need to produce more LNG and supply it wherever possible. Sadly many want to stop all fossil fuel production.
Also known as biomass. These are a renewable resource and massively better than fossil fuels when it comes to climate change. Obviously you need to ensure they are burnt in a controlled environment (not dumping smoke into people's kitchens, for example), but in the right circumstances they are vastly preferable to coal and gas.
Developing countries need not repeat the same mistakes as the developed world. We have better technology and far more options now.
Per BTU heat output, natural gas outputs more than half as much CO2 (about 60%) compared to coal. That's not "low emissions" by any stretch.
Plus, the entire natural gas distribution system is leaky to an extent that is not fully understood yet. Recent reports suggest it is very leaky. Leaking...methane, which is 80-200x worse than CO2 as a greenhouse gas.
Uranium has been extracted from seawater before. It's not economically practical, but it can be done, because seawater has uranium in it already. Tritium is also already in there.
Issues of concentration at the point where it is put into the ocean can be an issue, but once dispersed this won't turn the pristine, 0.0000000...% radioactive ocean into a radioactive hellscape, it represents an impercetible percentage increase of what is already there. That doesn't mean we shouldn't think about the implications, but "thinking about the implications" shouldn't start from incorrect understandings of the nature of the current world.
Earth is an amazing environment. It does an incredible job of giving us a low-radiation environment, compared to most of the rest of the universe which ranges from "dangerous" to "radioactive wasteland". But it's not perfect and we are not at a flat 0 even here.
And here is a good example of this in action. The optimal way to connect a nuclear power station to the grid is with a big overhead power line. Except that you would have to build it in a scenic area. Millions of people have a heuristic that make them believe thag powerlines damage the environment. There is no scientific basis for that. But you put the cable underground anyway at huge expense. The objective is to generate electricity, not deploy an absolutely optimal solution. And a piece of infrastructure built in the world has hundreds of issues like that. The only solution we have to that is politics.
Personally I don't disagree that nuclear is probably needed at least short term, but it's not a a reason to ignore or deny the problems it causes, some of them are hard to solve, and probably some also even hard to anticipate.
> In the 10 years since the Fukushima Daiichi nuclear power plant accident, public trust in the government and the power company has suffered. As the decommissioning process will last at least another 30 years or more, the Japanese government should reconsider how it makes decisions about decommissioning and reconstruction. Public concern related to the government’s recent announcement that it will release treated water into the sea is the tip of iceberg. It is the responsibility of the Japanese government and nuclear industry to manage this process successfully on behalf of all citizens of Japan and the world. The accident is not over yet."

Also, the ad hominem attack on people wasting their time on this kind of study is really weak. We should want proper reviews of all large scale industrial processes that release into the ocean. That does not preclude nuclear power.
Would that be like saying "carbon dioxide is already present in the atmosphere"?
The future is bright whether you see it or not. Take a vacation, find a less stressful job, start enjoying life.
Definitely not. There's a good argument to be made nuclear power in the 'global North' is relatively safe today. At the same time you will be hard pressed to find evidence that nuclear power was safe in the past or is safe today in politically unstable environments.
First of all, that isn't the same claim the post above to you was making. Second, [1]here's a chart showing the cleanest and safest power sources, backing up the claim made in the comment above yours. Nuclear is cleanest, and on safety it's close but falls behind the renewables (still 2-3 orders of magnitude safer than the fossil fuel sources).
This line of thinking is what brought about our current environmental clamities. Everybody says: Look, what I am doing to the environemnt is just a tiny, tiny bit of what others are doing. The end result is a massive destruction of the ecosphere. Every dumping of waste into the ocean is a liablity.
> the safest and cleanest way to produce electricity.
Only if you hand pick studies in favour of your opinion. The wast will be around until the end of humanity. No one really knows whether the optimists, who want to store it away "forever", will succeed. If not, ...
If the title had said "a million tons of tritium" it would be wrong, but it didn't.
The legal limit for tritium emissions for a nuclear plant in the US is a total of 0.2kg per year according to NRC. A metric ton is 1000kg. In order to get a million tons you would need 5x10^9 nuclear plants all releasing their maximum amount of tritium. If the amount would then be as diluted as in the article, ie 860,000 tons water for every 2.1 gram, you would then need 4*10^18 tons of water. There isn't enough water on earth to do so.
The article's title makes it sound like they're just going to dump the Elephant Foot directly into the pacific. It's clearly a sensationalistic anti-nuclear title edit.

The entire pdf is a worthy read.
It usually would fall in conspiracy theory territory, expect TEPCO did bullshit their facts and numbers at several critical occasions already, and the gov stays in lockstep with TEPCO.

The issue is not so much tritium, but rather that claims of removal of some 60+ other radionuclides (products of fission of uranium) to below regulatory standards remain questionable.
> "TEPCO and the Ministry of Economy, Trade, and Industry have acknowledged that more than 70 percent of the treated water at Fukushima contains 62 other nuclides that are higher than regulatory standards. Therefore, treated water may pose significant risks to the environment and public health and could damage Fukushima’s fishing and agricultural industry. The environmental, social, and economic impacts of releasing the treated water to the sea must be more carefully assessed."
Edit: Hey, look, somebody wrote a book with the latin thing I said as its title, whose contents I probably summarized the thesis of without even reading.

I wouldn't rely on that alone. I'd say they are more clean than concerned about ecology. You don't see thrash in streets or in forests, that's true. But their recycling is almost non-existant, they burn almost all the waste. They use (thick) packaging in absurdly high amounts (to an european eye). They have fishery and whaling issues…
The prefectural governments did not publish the results and did nothing in response to these surveys. The participants who had donated hair samples were not informed of their result, even when they requested it”
We're relying on mostly the same people, minus the pragmatic ones who went to bluer skies, to now make trade-offs related to how much Japan's willing to pollute the surrounding seas relative to the economic and politic situation.

1. Scientists: Japan’s Plan To Dump Nuclear Waste Into The Pacific Ocean May Not Be Safe
2. A panel of scientists has identified critical gaps in the data supporting the safe discharge of wastewater into the Pacific
3. Independent scientists are questioning Japan’s plans to dump just over 1 million tons of nuclear wastewater into the Pacific Ocean, following a review of the available evidence
4. Last year Japan announced that wastewater from the Fukushima-Daiichi Nuclear Power Plant, destroyed in March 2011 following the Tohoku Earthquake and tsunami, would be dropped into the Pacific in 2023
5. “So these are all the things we need to consider.” Confusing The Masses The Pacific Islands Forum convened its panel of experts – specializing in policy and different scientific disciplines – because of the highly technical nature of Japan’s plan
6. But panel scientist Robert Richmond, director of the University of Hawaii Kewalo Marine Laboratory, says the panel unanimously believes that critical gaps in information remain
7. Through phytoplankton, Richmond says, the radioactive element could then find its way into the greater food system as the microscopic plants are consumed by mollusks and small fish, which are later consumed by other fish and eventually humans
8. The IAEA is expected to deliver reports from its site visits in the next two months, according to its website, and would release a fully comprehensive report before any water is released
> Japan’s plans to dump just over 1 million tons of nuclear wastewater into the Pacific Ocean
But it omits to say that this is actually extraordinarily diluted: we're talking about around 20 grams of pure tritiated water.
The radioactive core is moving and will eventually be in contact with the water. It may already be. Does anyone know?[1]
If a dump of water used for cooling is a concern (and it is for me personally and I am open to learning it is not), is our situation not far more grave given eventual contact with the water and this source multiplied by however many world water cycles of contact will occur over the crazy long half life that hot core has?
[1] I saw some discussion on this early on and struggle to find it and or current info I trust today. Hoping others here know more.
Tritium, the thing ONE of the scientists is concerned about, is an isotope of hydrogen. It's barely radioactive, and it has half life of about 12 years. You may know it as the stuff that illuminates watch faces and sights. It's used in many other industrial applications and as far as radioactive elements goes
If you read the actual article you may see it's classic fear mongering:
The panel of multi-disciplinary scientists, hired by the intergovernmental Pacific Islands Forum, has not found conclusive evidence that the discharge would be entirely safe, and one marine biologist fears contamination could affect the food system.
TL;DR: They couldn't say something could happen, so they said that they can't conclude nothing will happen. Which is exactly what everybody knew before. One of them said that something COULD happen, but he doesn't know how.
Though it might be nice to see Godzilla IRL... at least until he/she squishes you with gigantic irradiated feet.
If only fossil plants were required to pay for burying their waste deep underground. Then we wouldn't be in the mess we're in.

Just look up the amount of water in the Pacific and then divide into the amount of waste water being discussed - the ratio is insanely tiny and nearly unmeasurable. The biological effects are far smaller because of this ratio than if you kept it concentrated on land.

Side note, seems like this could be sold to some research labs, no? Seems like if you need tritium using this rather than ocean water would be a good thing.
But hey, they can just drain the water into the ocean right?!?!
They both seem to have a standard of zero risk without comparison to the alternatives. (Yes, there are adverse events with vaccines, and even with the risk of those adverse events, they do far more good than harm).
There is overwhelming evidence for safety, but they keep bringing up theoretical risks and point to events in the past (see issues with rotavirus vaccine) to spread FUD. Thins ends up hurting everyone.
Even if China allow them to dump the water into the Gobi desert, it'd still cost billions of dollar to build and operate the pipeline. It'd never happen.
