Tepco has been Storing Radioactive Materials at the Sea for a Month


Friday, 24 june 2011

Its was official one month ago! TepCo is using Mega-Float - a large steel floating structure to store contaminated water from the tsunami-crippled Daiichi nuclear power plant. At least thats what we were officialy told a month ago. From what we know now they could be also storing spent fuel rods directly in the steel crates floating in the ocean, using it as a cooler for iradiated hot materials. 

On the 22nd of june we have presummed that TepCo is dumping spent fuel rods into the sea - a far fetched claim, but this one-month old news is another piece of the puzzle.  Big chunk of the puzzle actually!

For those who were following the story from the beggining this will shine some light on recent events. Newcomers please read the previous articles related to the story, to get a fair insight into our deep and sophisticated levels of.... well... paranoia.

On the 21st of May the arrival of the Mega - Float, large steel floating structure into Fukushima has been widely reported all over the news and extensively covered.  You can flashback to RT News article Giant "Mega-Float" comes to rescue at Fukushima for the official coverage and some interesting info that you might have forgotten.

Like the one that the contaminated water contained radioactive cesium 620,000 times higher than the government-set safety limit.  I guess to the people in panic any such behemoth as Mega - Float was actually a welcome sight and indeed gave a light of hope to the confused and traumatised people of Japan.

But what good does it really do storing huge amounts of highly radioactive materials at the sea, especially right after the Tsunami experience?

Then as is usual with such events, news went silent. It might have been that if the news would stay around for awhile, people might start asking if holding such highly radioactive waste in the middle of the ocean is really a good idea. They might wonder if such containments that were never intended to hold radioactive materials are really a viable option. They might wonder if such containments might "eventually" leak. The above picture is not a comforting sight, to say the least.

But the vessel(s) might actually be one of the best cost-cutters for TEPCO. They are scalable, upgradable and you can attach as many floating units as you like to the existing floating platforms. And indeed there seems to be more than just one  present judging by the photographs.


The structure that is 7m tall, and is 5.5m submerged in the water would provide a constant flow of cold sea water for any containments located underwater, therefore it would be sensible to conclude that Tepco is rather than spraying the seawater into the leaking spent fuel pools, creating floating pools at sea that need no special cooling, since there is an abundant flow of cold sea water. At least that would be the "get rid of the bottlenecks mentality" typical for corporate thinking.

With all that said, since they are allready storing (we dont know how much) radioactive water in these platforms, why not create floating pools for spent fuel rods also? To say the least it would be practical and cost effective. Obviously the enviornmental issues are never the high agenda on the nuclear industry table, so whats stoping them? The modular design is also very practical in case one of the containers overheats or leaks... Can that explain the mysterious rigs and the strange smoke we were reporting about?
