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.
