Nuclear Fuel could have Melt through Pressure Vessels ... Government Report
On Jung 7, the whole content of government report to be submitted to IAEA has been revealed, regarding TEPCO's Fukushima No. 1 Nuclear Plant.
The report points out the possibility that molten nuclear fuel leaked out of the bottom of damaged pressure vessels in Reactor Unit #1 to #3 and accumulated in the containment vessels.
Molten nuclear fuel falling down to containment vessel is called "melt-through" and this is the worst case which is beyond meltdown. It also says that the location in pressure vessel where control rod passes through was damaged, and water tainted with highly radioactive substance was leaked out. This is the first time that government admitted the possibility of melt-through.

P!
Does it continue to melt through?
It can...and probably has caused holes and leaked through..but the nothing to see here crowd will naysay and say it hasn’t.
But then again, they also claimed what we are just now finding out probably didn’t happen, as well.
This is an interesting article

In totality with all of the ramifications..this will be worse than Chernobyl.
China has sold off our debt. Japan will be next to pay for this disaster.
This is a good blog to read
he translates news articles
Here is an article for those that claim radiation isnt a problem
http://www.nytimes.com/2011/06/07/business/energy-environment/07radiation.html?_r=1&ref=business
And here is the striking statement..given what you have seen from the Japanese Government...would this really surprise you:
“
As if this were not complex enough, another school of thought suggests that the radiation effect on people exposed at Hiroshima and Nagasaki was worse than the official statistics show. “
I doubt that the Japanese disaster will be as bad as Chernobyl. The Chernobyl disaster was exacerbated by the fact that it was a graphite moderated reactor. The graphite burned and the fire dispersed the radioactivity far and wide. The Japanese reactors are certainly an intense local disaster but will probably not have the far reaching effects of Chernobyl.
Tellingly, despite three confirmed meltdowns, to my knowledge not a single person has died as the result of the Japanese disaster.
You’re correct. At least the latest news speculation is that “maybe” there was a melt through which counters the view by some that a melt down means the reactor vessel was breached. Form what I’ve read it appears possible that the torus connected to the reactor vessel may have leaked.
The key is that anything from the reactor or associated systems is still contained with in the primary containement and possibly the drywell.
A day late and a dollar short. Yet? Check back in a few years after the cancers and birth defects start showing up.
No, the latest news is that there were three full meltdowns.
That is what happened at TMI. The melted fuel and internals still remained within the reactor pressure vessel. The news article mentioned a possible, not definite, melt-through of the reactors. As I explained that could have been the torus which is external to the reactor vessel.
What is confusing the issue is the pressure readings are inconsistent.
“Tellingly, despite three confirmed meltdowns, to my knowledge not a single person has died as the result of the Japanese disaster.”
If you read the article, the deaths will come years from now. Many know they are already dying.
A few weeks ago I read an analysis that stated very little if any of the actual graphite burned. We have some of the analysts here (PNNL) and I am going to try to get clarification from them.
http://news.blogs.cnn.com/2011/06/06/3-japan-nuclear-reactors-had-full-meltdown-agency-says/
“Japan’s Fukushima Daiichi nuclear power plant experienced full meltdowns at three reactors in the wake of an earthquake and tsunami in March, the country’s Nuclear Emergency Response Headquarters said Monday.”
But, hey, you know better than they do.
Radiation levels from an independent source:
They are slowly challenging government credibility, trying to confirm their suspicions which has been sneaking up for some time.
For the disaster which require immediate and full-scale action from the get-go, response has been so slow. This kind of slow actions can be costly but the damage can be repaired in other cases. Not this one. This is a catastrophe.
