Tritium is a valuable resource, as deuterium-tritium fusion is orders of magnitude easier to achieve than the next best alternative, deuterium-deuterium fusion. There is a coming tritium supply crisis, with most of the world's supply slated to be gobbled up by the ITER experimental reactor in the near future, leaving the world with a dearth of fusion fuel. It is a shame that there is not the means to extract that tritium from the contaminated waste water. (The environmental consequences of the release are negligible).

As Above So Below
The cost is likely exceedingly high to extract tritium from wastewater, at least according to the statements from a company linked and quoted below...They are claiming to have a way to economically remove tritium from light water...
Our Modular Detritiation System (MDS®) to Remove Tritium
Tritium Is a radioactive form of hydrogen. The economical removal of Tritium from light water was deemed impossible until Veolia Nuclear Solutions changed the paradigm.The decontamination of Tritium (T) is particularly problematic: it is a special form of hydrogen that creates tritiated water (HTO vs. H2O), which does not lend itself to removal by conventional technologies.
Tritium is routinely released into the environment by commercial nuclear power plants. Until now, no technology existed to remove low levels of tritium contamination economically. We are changing the paradigm by blending complex innovation and simple economics.
Our Modular Detritiation System is based on proven technology that has been used commercially for over 30 years, providing nuclear operators an economical path to strengthen public trust and improve energy production with a new – and proven way – to remove Tritium.
The MDS® is a Tritium management tool for processing large volumes of light water across a range of concentrations. This technology is based on the working principle of combined electrolysis catalytic exchange (CECE) and releases only clean oxygen and hydrogen with no liquid effluent. The technology builds on proven heavy water solutions, and although developed with a focus on light water, it can also be adapted for use in heavy water detritiation.
The system is designed to reduce the volume of tritiated water which allows for reuse and recycling of Tritium instead of its release into the environment. This process takes diluted tritium and concentrates it so it can be recycled or reused while reducing the amount of Tritium released to the environment.
* Economical and scalable design
* Reduces volume of water by 100,000 times
* All Tritium to be captured in metal hydride at molecular level and stable up to 600° C
* No water remains after treatment is complete
* The MDS® has been in operation for over 1,000 hours over a 9-month period. Our U.S. Richland, Washington facility continues to support verification testing and scoping studies.

Okay you eat this: Fukushima fish with 180 times legal limit of radioactive cesium.
Monitoring long-term ecological impacts from release of Fukushima radiation water into ocean
"If the nuclear wastewater is released into the Pacific Ocean, there will be potential risks in the coming hundreds or even thousands of years."Methinks the claim that the environmental consequences are "negligible" can be added it to the claims that "vaccines are safe & effective" & "More doctors smoke Camels"

Neither of those links is specifically relevant to the story I was responding to.

Narrowing the goalposts is the same tactic as moving them. In other words, a response doesn't have to be "specifically relevant" to be relevant. I suppose that widening them too far can also be a valid objection — but I don't think I've employed any sort of straw man here. The response is specific to the type, cause, and location of the pollution.
In other words, just because the exact same particles from the release in question aren't in the specific contaminated fish used as an example, doesn't invalidate the point that the same type of particles from the same type of release from the same location don't apply to similarly contaminated fish.

Well then show evidence of fish with dangerous levels of tritium contamination.

Tritium alone isn't the issue. With that in mind — your point is well taken, as is @nivek's. In an ideal world, I'd have built only a few experimental reactors to advance us toward fusion and supply the byproducts useful in medicine and industry, while reducing risk and cleaning-up the waste in a more manageable fashion. So don't get me completely wrong. It's not that you haven't made a valid point where your main concern is. I just have a soft spot when it comes to environmental pollution — so I have to admit that my own bias is a factor. That said, I'd argue that of all biases one could have, it's not a particularly bad one.
Does that sound fair?
