#Fukushima I Nuke Plant Waste Water Leak: TEPCO Insists It Was Only 150 Milliliters That Leaked into the Ocean

12 tonnes of waste water after the reverse osmosis leaked when the Kanaflex hose decoupled, but TEPCO says hardly any of that water reached the ocean. Rejoice.

150 milliliters is 150 cubic centimeters. One liter is 1,000 milliliters, or 1,000 cubic centimeters. 1 tonne is 1,000 liters.

So, TEPCO is telling us only 0.00125% of the waste water leaked into the ocean. OK, then. Where did the water go?

From Jiji Tsushin (4/6/2012):


TEPCO calculated the amount of the leak into the ocean as "150 milliliters", out of 12 tonnes of waste water that leaked at Fukushima I Nuclear Power Plant


TEPCO announced on April 6 that only about 150 milliliters of the 12-tonne waste water that leaked from the pipe in early hours on April 5 from the contaminated water treatment system at Fukushima I Nuclear Power Plant made it to the ocean.


TEPCO collected samples of seawater at the south water discharge outlet for Reactors 1 through 4 in the morning of April 6 and measured the radioactivity. The result showed the density of beta nuclides was below the detection level (0.018 becquerels/1 milliliter [cubic centimeter]).


In the sampling test done in the afternoon of April 5, it was 0.024 becquerels [per 1 millimeter], only slightly above the no-detection level. TEPCO's Matsumoto said the density would be much higher if the leak was in tonnes, and put the amount of the waste water that leaked into the ocean at about 150 milliliters.

Well, considering TEPCO is pouring 23 tonnes of water PER HOUR total into the broken reactors, 12 tonnes may not be much at all, except for concentrated beta nuclides.

150 milliliters ?????

Reporting a 10 Tablespoon leak ?????

SNAFU reporting at it's best.

apparently each reactor is being fed 9 tonnes of water an hour.

that's kind of about a tanker full for 4 reactors, each hour.

and decommisioning will take 30 years (cough cough).

A semi trailer, per hour, per day, per week, per year, per decade equals roughly 10 million tonnes of water over 30 years.

'A cubic meter of pure water at four degrees Celsius weighs 1000 kilograms, or one tonne (a metric ton).'

'8 million m³ — volume of chalk excavated in the construction of the Channel Tunnel'

'3.33 million m³ — volume of concrete in Hoover Dam'

Impressive, they must be quite confident in their calculations and error margins, to be handling numbers on the scale of millions of cm3 and end up with a leak amounting to less than dog piss...

Surely, someone saw the drops running for the ocean and counted them. Or maybe they caught it with spoons but unfortunately spilled 10 of them ? What happened with the dainichi spill by the way, any news about that ? Weren't JAEA/IAEA/Some-other-nuke-clowns supposed to investigate ?

when tepco says detection (or ND) = minimum bullshit level. probably will quote meant mega litre.

18 Bq per litre (corrected - by my *1000 calc) - is absolute BS too. Thats more like Tokyo water

Really interesting article.
