This is what happens when we let nuclear industry to regulate itself.

Rosa Yang, a nuclear expert at the Electric Power Research Institute, based in Palo Alto, California, who advises Japan on decommissioning reactors, believes the public angst is uncalled for. She says a Japanese government official should simply get up in public and drink water from one of the tanks to convince people it’s safe.

She should do so first. But I think no one will be convinced even if she drinks the radioactive water.

Sure, I believe Tanaka 180%!

Tritium is safe so let's just use the stored tritium in water in car washes in Tokyo and as toilet water at Shinzo's house.

And save some for Rosa Yang and her family in California cuz they dig tritium flavored water!

Seriously, I hope Greenpeace should sue Tokyo for polluting earths Pacific Ocean.

Not just one Japanese official, but all those, Japanese and otherwise, including Ms. Yang and the usual suspects on JT, who keep telling us vociferously that nuclear power is 'perfectly safe'.

Not just one of the tanks, but all the tanks. Not just 'a drink', but use it as their sole source of water for drinking, cooking, washing, bathing...when it's all gone, and all these pro-nuclear 'experts' are still in glowing health, then maybe those of us who eat seafood might consider eating fish that have been harvested from tritium waters.

Maybe 'glowing health' wasn't quite the right phrase...

Unfortunately, releasing it to the sea for dilution is probably best - vastly preferable to allowing it to leak into aquifiers. At the same time, an area off the coast of Tohoku must be declared off-limits to fisheries. There would be a silver lining here: just as wildlife has seen an astounding rebound in the areas around Chernobyl, so could a marine preserve around Tohoku contribute to the revitilization of the vastly over-fished waters surrounding Japan.

These hastily-built tanks are already rusting and leaking, so it is really now just a question of time and timing, as has been said above.

The only question left is where to allow it to flow, either to filter down into the aquifers, or into the sea, or both.

This is our legacy.

Do you remember the earthquake and tsunami debris from Tohoku reached California in just a couple of months? If you release the radioactive water into the Pacific, the entire Pacific Ocean as well as the Indian and the Atlantic Oceans will be contaminated.

Restricting fisheries on the coast of Tohoku is meaningless measures to create false sense of security.

So.... 800x more tritium makes its way into the English Channel everyday thanks to La Hague nuclear reprocessing plant in Normandy France, but no one is making a stink about it.

Sorry it's only in Japanese.

But this reminds me of the BP oil spill that was reported as the end of the world in order to take down Obama, but no one talks about the on going oil leaks in Nigeria or tries to do anything about it.

Much like how terror attacks that happen in a western country are reported on for days, but it's hard to find reporting when they happen elsewhere.

I wonder what the effect would be of taking this polluted water and dumping it in the Pacific at the farthest point from land, taking into account ocean currents, and allowing it to be diluted in the vastness of the Pacific Ocean? Or perhaps, filling an old tanker with the polluted water and sinking it into the Marianas Trench, the deepest part of the ocean.

Just build new tanks and transfer the contaminated water into them. TEPCO or the government can keep on renewing the tanks until the radiation diminishes to non-detectable.

Simple solution.

That's a bit of an exaggeration. It would take a ridiculous amount of radioactive water to pollute even a small part of either of these oceans. There is a lot of water in these oceans. I mean a lot of water. There is so much water that it's hard for us as humans just to grasp exactly how much water there is in the oceans. But suffice to say it's a lot.

Don't forget people, to recycle and collect your old aluminum cans and make sure you plant a tree today !! ok ?? who cares we have Chernobyle burning for how many years now ? Do we test the air , food ?, milk ? , fish we eat? I don't know do we ? I have noticed more cancer centers popping up nation wide.

If that water is merely used for cooling the core then why can't it simply be reused for that purpose even though it has nuclear contaminants? Why keep pumping tons of fresh clean water in there to get it contaminated instead of just cooling it with the already contaminated stuff that must eventually be stored and cleaned up?

0 ( +0 / -0 )

Well, while I feel very sorry for the fisheries and related industries, if this happen I think we must all boycott, and convince other nations to as well, products along the Fukushima coastline as well as a number of other adjacent prefectures. No one has any right to object to such boycotts. Let TEPCO compensate the industries BEFORE dumping.

And to prove it's safe, not only should Japanese officials, but anyone who supports nuclear power, should have to drink such water, for at least a few years, as well as use it for daily life, and in their cooking in particular. THEN it might be believed that it's safe. Start with Abe and all the TEPCO execs, though, with a daily morning live broadcast of them drinking water proven to be from water around the plant.

Tritium goes directly into soft tissues and organs of the human body

Tritium also rapidly leaves the soft tissues and organs of the human body. It has an effective half-life of 10 days.

She should do so first. But I think no one will be convinced even if she drinks the radioactive water.

Then why should she do it? But thanks for pointing out that nothing will reduce the irrational fear that some people have.

and the usual suspects on JT, who keep telling us vociferously that nuclear power is 'perfectly safe'.

No problem. Ship me as much as you want, even though I have never said nuclear power is 'perfectly safe' and don't remember anyone else saying so either.

might consider eating fish that have been harvested from tritium waters.

ALL water has tritium in it and it always has. So if you have ever in your whole life eaten fish then you have already eaten fish harvested from tritium water.

0 ( +3 / -3 )

Tritium has a specific activity of 9.7E3 curies per gram. 3.4 petabecquerels is therefore about 9.5 grams of tritium. This is an utterly insignificant amount of tritium, even before you dilute it into the entire ocean.

Re: "...Ridding water of tritium has been carried out in laboratories. But it’s an effort that would be extremely costly at the scale required for the Fukushima plant, which sits on the Pacific coast. Many scientists argue it isn’t worth it and say the risks of dumping the tritium-laced water into the sea are minimal...."

Tritium is used in REAL, (Vs. the Bush-Blair-Iraq-Imaginary...), N.-W.M.D.'s, as a megaton-yield-booster...

Sorry if it's getting REALLY, really expensive to maintain this mechanical_affront to humanity / vainly, attempt to control the dangers of N-elements...some of which stay, dangerous for time-periods, longer than humans have walked the earth, but... The Japanese government, 'N Tokyo Light, 'N Power took it upon themselves to place a multi-reactor N-power-plant where a Tsunami / Earthquake could destroy it, all the while endangering the rest of us, so... I have ZERO sympathy!

FYI, titrium has a half-life of just over 12 years, and a biological half-life in the human body of 7-12 days.

IOW, if released, it will be around for over a decade but it does not bio-accumulate.

Finally, it would be nice to know the concentration in the tanks.

What I find absolutely unacceptable after this whole fiasco, is they still want to put nuclear power plants around the world! We have no idea what we are doing, how to store radioactive waste so future generations have a clean , optimal planet. The lunatics are running the world.

Turns out the effects of tritium on phytoplankton are well understood. Tritium is naturally occurring, so any phytoplankton living now has been exposed to tritium. Previous generations of phytoplankton were also exposed to tritium (going back farther than human history), so we have solid evidence of the effects over multiple generations as well.

More recently, above-ground nuclear testing releases more tritium than the levels under discussion here, so we have 80+ years' worth of data on the effects on marine life.

Farmboy,

What I meant was EXACTLY what I wrote. Tritium has an effective half-life of 10 days. Effective half-life is the combined effect of radiological decay and biological removal.

Good grief the nuclear hysteria crowd is out in force again. A quick google expedition will show you that the with its weak radiation and short half-life of 12 years, there is no issue at all.

And by the way, here is from Wiki:

"Tritium occurs naturally due to cosmic rays interacting with atmospheric gases. () Worldwide, the production of tritium from natural sources is 148,000 terabecquerels per year. The global equilibrium inventory of tritium created by natural sources remains approximately constant at 2,590,000 terabecquerels. "

So, no screaming missives against cosmic rays yet? We are doomed!

2 ( +4 / -2 )

For all of the people sounding off, what do you suggest they do? And if your reaction is "Well, just store it!" then the question becomes where, for how long, until what standard is reached, etc. There is little or no public consensus on these issues, and without a consensus there are not likely to be solutions. What happens if they do release the tritium? What does that do to the environment? Is tritium naturally present in all water (yes, it is). How much will releasing it cause that to rise, locally and in the world-wide water supply? Is the change even measurable 1 km away out to sea? I don't know these answers, and without them I have NO opinion.

The silly fear mongering is sad. Tritium is only dangerous when it's loaded into a hydrogen bomb. It's used for watch dials and gun sights and is hardly dangerous. 57 millimeters in the ocean will never be noticed.

FarmboyAPR. 13, 2016 - 12:30AM JST The problem is that there is some, probably small, effect on the body while it is there, but since we're talking about a huge dump into the environment, every glass of water will have that same small effect.

Uh, two things: First of all, every glass will not have that same small effect because the ocean is a teenie bit larger than the man-made tanks TEPCO is storing the water in now, so the tritium will become vastly less concentrated. To an order of magnitude most people don't even comprehend. When a homeopathy salesman promises that diluting the active ingredient to miniscule quantities provides the same small effect throughout the container, sensible people rightly proclaim them to be a fraud. Do you think making the active ingredient radioactive magically changes the rules?

Second, uh, I don't know about you, but most people don't drink glasses of sea water.

This is the largest release ever. It will be measurable world wide, as it will increase the global amount of tritium about 20% (rough estimate) in ocean water (just a guess). Holding up the beaker was political spin to say ... looks so little. But it is significant. The atmosphere produces 5.0 to 7.0 x 10^16 Bq, annually. This is 50-70 peta Bq. The plant will release 3.4 pete Bq. This is roughly 10% of annual atmospheric production. It will be measurable since it will be in the ocean. Since, the tritium in the atmosphere moves downwards into the ocean ... this will be a large spike in the oceans, as atmospherically produced tritium decays on the way down. I guess from a human exposure standpoint, it is a low risk proposal, but the effect on the marine ecosystems, is not so easy to predict. This is a sad situation ... no matter how you look at it.

Here is a leak of which there were any at Fukushima Daiichi Nuclear Power Plant that was Reported by TEPCO.

TEPCO announced in a press release that 2,029,900,000 Bq of Cs-134/137 leaked as contaminated water in Fukushima plant.

According to Tepco, a leakage detector of waste incineration building went off around noon of 3/23/2016.

Tepco reports the leaked volume was 5.3 t. The leaked contaminated water was from the cesium absorption facility to contain extremely high density of Cs-134/137.

From Tepco’s announcement, Cs-134/137 density was 383,000,000 Bq/m3.

All β nuclides to include Sr-90 was 480,000,000 Bq/m3.

At the moment of the press release, Tepco had not completed removing the leaked water but they state the building is designed to retain contaminated water inside.

The pipe from the cesium absorption facility was cut off due to a construction however somebody turned on the facility to cause the large leakage.

I have read that tritium would make a much safer nuclear fuel than uranium just because of the greatly reduced radiation risk, and it's more common than uranium. Maybe it's not unsafe to release it into the sea on a one-off basis. And if it is safe fissionable material, why aren't they using it in reactors?

That tritium laced water is perfect to use with cement to Entomb Fukushima Daiichi Nuclear Power Plant.

Actually using it to make cement is a great idea. Tritium only gives off very low energy radiation, the outer layer of skin will completely stop it. So it is only a concern (and a very very minor one) if taken into the body. If used in cement the radiation wouldn't be able to harm anyone and the cement would last for long enough for the tritium to have all decayed away.

But entombing the plants is, on the other hand, a foolish idea.

The thyroid testing of Children in Kashiwa City Chiba has shown and increase in cases of Thyroid Abnormality. I am show this Tritium waste water being poured into the ocean will increase these numbers.

First of all, the increase in cases is because of all the testing. The same increase was noted in South Korea long before Fukushima when they started testing everyone. And testing of children in Japan far away from Fukushima also show the same effect. Autopsies have shown that just about EVERYONE has some abnormal cells/cysts in their thyroid and in almost all cases these cells/cysts never cause any harm.

Here is one of many articles that explain what is happening and why it ISN'T related to radiation or Fukushima.

https://www.sciencebasedmedicine.org/confusing-overdiagnosis-for-an-epidemic-of-thyroid-cancer-in-japan-after-fukushima/

Second of all, radiation induced thyroid cancer is almost exclusively caused by iodine-131 NOT tritium.

And if it is safe fissionable material, why aren't they using it in reactors?

Because it isn't fissionable. It is used as fuel in FUSION reactors. And at present there are no man-made fusion reactors that produce more power than they use.

Homeopathy has nothing to do with tritium release planned by TEPCO.

But the analogy that WilliB mentioned DOES have something to do with the tritium release.

I remember nuclear industry once advertised that exposure to radiation makes people healthier

I highly doubt that the nuclear industry ever advertised any such thing.

But studies of low level radiation exposure have shown a possible beneficial effect.

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2477708/

Approximately 10,000 people occupied these buildings and received an average radiation dose of 0.4 Sv, unknowingly, during a 9–20 year period. They did not suffer a higher incidence of cancer mortality, as the LNT theory would predict. On the contrary, the incidence of cancer deaths in this population was greatly reduced—to about 3 per cent of the incidence of spontaneous cancer death in the general Taiwan public. In addition, the incidence of congenital malformations was also reduced—to about 7 per cent of the incidence in the general public.

why is tritium a substance which is used to make thermonuclear weapons?

Steel and wires are used to make thermonuclear weapons too. Should we be afraid of steel and wires?

Tritium is used in weapons in conjunction with deuterium (which is a NON-radioactive isotope of hydrogen). The initial nuclear fission blast of plutonium creates high enough temperatures and pressures to cause the tritium and deuterium to undergo fusion releasing a little more energy and lots more neutrons, those neutrons ensure that more of the plutonium undergoes fission. Without the tritium-deuterium 'boost' some of the plutonium wouldn't fission. So the tritium increases the yield without increasing the amount of plutonium needed. It also reduces the size for a given yield and allows for adjusting the yield during arming.

So unless the tritium encounters massive temperatures and pressures (like inside the sun) it isn't a weapons hazard and is safe and weak.

All of this info can easily be found on the internet for anyone who is actually interested in facts and not just wanting to spread fear.

I have over 30 years in the US commercial nuclear industry. Tritium is a normal byproduct of all reactors and has no measurable impact on living organisms. The beta decay (a fast electron) has so little energy it cannot penetrate skin. The byproduct is helium, completely inert. The amount t be released by Fukushima will have no effect on people or marine life.

People who are anti-nuclear use any mention of radioactivity to instill fear in the uninformed masses. It has been five years since a disastrous natural phenomenon wrecked three reactors at Fukushima. There is no mention that nobody has died or gotten sick from the effects of radiation due to the event. Look at facts, not fear mongers.

Perhaps we should look at the facts regarding the thousands of livestock and pet animals that died of starvation after being abandoned in the no-go zone, or were culled.

Or we could look at the financial loss to the farmers who lost their farms and cattle.

Or the hundreds of thousands of people who lost their homes and will never be able to return.

The businesses and livelihoods that were lost.

The towns and communities that were evacuated and will never be restored.

But nobody actually died from radiation, so it's all OK?

Most of the commenters subscribe to the LNT (Linear No Threshold) theory which has been disproven many times. I saw no mention in the article about the half-life of tritium, and only a few in the comments. And nothing about the radiation level compared to the background radiation we get all the time--even more if you fly or live at high altitudes. Yes, small amounts of radiation appear to be GOOD for living tissue. I suggest all of the water be dumped; but to reduce the impact on the LNT people, dump it gradually and away from any drinking water intakes. (Gradually means the cooling water for the day, plus one tank.)
