TEPCO To Sprinkle Low-Contamination Water from Reactor 5 and 6 Turbine Bldgs in the Fuku I Compound

after they treat the water to remove as much radioactive materials and salt as possible from the water.

TEPCO seems to be running out of storage space for contaminated water, and at the same time is worried that the wood piles may catch fire after the trees were cut down to make room for storage facilities on the west side of the plant.

From Yomiuri Shinbun (9/22/2011):


TEPCO disclosed the plan on September 22 to treat the low-contamination water and sprinkle the treated water in the Fukushima I Nuke Plant compound. The low-contamination water came from Reactors 5 and 6, and is currently stored in temporary storage facilities.


The company says there will be hardly any effect to the surrounding environment, but there may be objections from the local municipalities.


In Reactors 5 and 6, a large amount of seawater flowed into the turbine buildings and other buildings when the tsumani hit. In addition, rainwater and the groundwater have seeped in. TEPCO has been transferring this low-contamination water to the temporary storage tanks and to the "Megafloat", and there are currently 16,350 tonnes.


Tepco has been clearing the forest inside the compound in order to set up the temporary storage tanks. The company is planning to sprinkle the treated water on the wood piles and the surrounding areas to prevent the wood piles from catching fire and to suppress the dust. The water will be treated to reduce the density of radioactive materials to the level allowed for the ocean bathing (50 becquerels/liter and below for radioactive cesium), and be desalinated.

Asahi Shinbun has the information on how "low" the contamination is in this water, and it is 0.01 becquerel/ milliliter (= cubic centimeter). So, in one liter the density is 10 becquerels/liter. If both newspapers are right, then TEPCO will only have to do the desalination.

This to me was the most bizarre story to come out of Tepco in a while. The latest typhoon just dumped huge amounts of water all over Japan. There is absolutely no need to spread water around to reduce fire risk. They are actually increasing the fallout level by doing this. I'm OK with the idea of turning Fukushima Daiichi into a nuclear waste site (let's face it, it already is) so storing the water there is OK with me, but spreading it around the site to "reduce fire risk"?? Facepalm.

They are running out of storage space, clearly. 10 becquerels/liter radiation is lower than the provisional safety limit for water and milk for babies in Japan (which is 100 becquerels/liter).

Does anyone believe TEpco on this

I don't believe Tepco. Let's not suffer from short term memory loss, here. It was only a few months ago when they dumped huge amounts of so-called low radiated water into the ocean, which turned out to be not so low.

In Japan, "It's better to apologize later than ask for permission beforehand." (as the saying goes.)

I'm sure none of this will impact the fantasy road map TEPCO has been dreaming about. I'm surprised they don't just make another ocean dump like they did in the early days of the disaster. At 10 Bq/L this water could be sold as a health drink in Japan. Fire suppression could be done by selling the wood to coffin makers for super eco-points. Maybe they can give TEPCO eco-points for "sprinkling" the water instead of just dumping it.

TEPCO's Apocalypse is to be delivered in the Now, and repeatedly.

True to form, they deliver.

Next? Guided tours for the radiation tourists. Yes, on site.

And we can watch and wonder how long before the compound is reduced to temperate tundra where nothing grows, 'inexplicably'.

Do they have a roadmap target date for the tundra?

And the target date for burning the wood piles?
