There was a quake near the coastline of Fukushima today. USGS had it as a 5,9. GFZ as a Mag. 6 quake. http://geofon.gfz-potsdam.de/eqinfo/event.php?id=gfz2013jqtk
When seeing that this morning it reminded of the times when i watched the news about Fukushima on TV. This happened in the direct aftermath of the devastating Tōhoku quake and Tsunami which struck Japan on March 11, 2011. (http://en.wikipedia.org/wiki/2011_Tōhoku_earthquake_and_tsunami) I am certain many here remember the terrible videos and images.
I asked on VC if such a quake as today would have harmed the nuclear powerplants near the coastline if the incidents 2 years ago had not already happened and Carl ensured me, the plants were built to withstand such an earthquake unharmed. What was the problem was, that the Tsunami was more than twice as high as the Fukushima plants could handle.
I remembered hearing of problems with a second atomic power plant back then, Fukushima II also called Fukushima Daini. Then there was a message in the news on local tv, that the situation was dealt with and nothing happened suggesting there was no further threat of a possible melt down or contaminated water escaping.
I had forgoten about the second power plant story till today. What happened in Fukushima I was too severe to be covered up and is now a topic in the media rather often. I just recently watched a documentation about a study on mutated butterflies in the region around Fukushima.
But what about Fukushima Daini? http://en.wikipedia.org/wiki/Fukushima_II_Nuclear_Power_Plant
I read it had a cold shutdown. So i asked you people here on VC
The Wikipedia ariticle says, that Tepco wanted to release the remaining 7000 tons of seawater back into the sea in July 2011 since the reservoirs holding it back started corroding but did not get permission to do so. Now it is more than 2 years later… what happened to the water till 2011?
What I heard, but don’t know the sources anymore: They have to keep water running over the reactors to cool them down. The trouble is the cooling water becomes radioactive due to close contact with the reactor. Sometimes they have to change the water because it becomes that much radioactive the pipes/watertanks start to corrode. I believe in April this year they had a leakage and a lot of radioactive water leaked in the ground and pacific sea. I believe they have huge storrage problems for the water. They still want to dump loads of water in the oceans.
This is a press release from 14 may 2013:http://www.japantoday.com/category/national/view/tepco-seeks-permission-to-dump-groundwater-from-fukushima-plant-into-ocean?utm_campaign=jt_newsletter&utm_medium=email&utm_source=jt_newsletter_2013-05-14_AM
Without checking the specifics regarding the water.
But, the powerplants are well able to take a 6M earthquake, the japanese ones are also actually secondarilly strengthened against earthquakes above any other powerplants on earth.
Problem was that they where not built for the 9.4M earthquake that hit Fukushima. Nothing in the end is built to take that. Problem is that the japanese plants should all have been on the other coastline for safety reasons.
In the end a nuclear powerplant should not be built in an area like that where you have had numerous historical ultralarge earthquakes. And… One should not build them at all since they do time and again release crap. Even when there is no accident the mining is poisonous enough. Blekh!
Does anyone have more informations on Fukushima Daini and the contaminated water? Was it released into the ocean? Did it just leak out?
Nothing much is going on with volcanoes as far as i could grab today, so in agreement with Carl, i thought to make a small post of my worries. After all, even though Japan is really far away from Europe. In case the radioactive water is in the Pacific Ocean it will have an effect. Not only the local fishermen might be affected. Fish is shipped and traded all over the world. And who knows which other species might be harmed , or where the ocean currents will carry the radioactive water.
