In the US those reliefs are tested regularly. Why would someone want to deliberately stop the rescue of Fukushima? I thought the explosions that happened were because of the hydrogen buildup.
Btw, I used to drive by San Onofre from time to time when I lived in S.D. And I always thought that was a bad place to put a reactor.
In the Navy reactors are operated at an extreme high degree of safety and the lack of accidents has proven that the system works.
I read an article today about the problems with the cleanup crews and organized crime being involved. Not good.
I don't know how much of what I say is exactly correct either. But I have been 'on' this since day one, and I have augmented my sum of knowledge of the event gradually and what I say here is true to the best of my knowledge, and the knowledge I have is way better than average.
The water molecule will return to its atomic elements somewhere around 1,500C (Very approximate). When the reactors overheated, this minimum required temperature would have been exceeded by several times.
Hydrogen and oxygen present in a round-about ratio of 2:1 will be inclined to recombine and form water at any time. The shockwave from the oxidizing of hydrogen travels at phenominal speed - no flashback arrestor can be trusted with oxygen and hydrogen in a stochiometric mix, and when it goes, virtually nothing will contain it. An over-sized pressure cooker in a concrete building couldn't hope to be able to withstand the entire contents igniting. You can see the shockwave in a couple of the reactor explosions that were caught by news cameras on 3/11/11.
If you are unwise enough to collect H and O in a 2:1 ratio, then you are in possession of an extremely dangerous container that could go off at any moment. The can it's in could have a temperature imbalance or just someone banging the cylinder might be enough to set it off.
HO explosions are first the thermal expansion and then the formation of water makes the area a relative vacuum. It's lethal stuff and I should know because I've researched it and also had the stuff blow up on me! ... Maybe only a few hundred cc of the stuff was enough to knock me against the wall. Tens of thousands of cubic litres of that stuff will easily blow the lid off the reactors and knock the walls out - which is what happened.
I think reactor number three was a nuclear explosion. That's the one that was being used with MOX. The reactor wasn't designed to use or intended to use MOX, but someone wanted to get even more 'free' power. Mox uses a little less than 10% plutonium and is much hotter than common-or-garden fuel rods. MOX wasn't used at Chernobyl.
Why would anyone want to blow up some nukes? Well it's happened, so think a bit harder. Perhaps it would be of assistance if I pointed out to you my belief that any politicians who are genuinely patriotic and have their electors' best interests at heart are sacked. It's nothing like it's the J gov trying to save the country or some such romantic nonsense and besides, the politicians are working for the central banks and those banks are working under the international banks - so follow the money - see if there is a way people can get money and/or power as a rusult of nuclear power stations blowing up.
Rumour has it that stuxnet escaping from Iran and infecting major infrastructure with Siemens operating systems was an accident. Stuxnet was discovered in the Sendai servers in June '10. It was not difficult to introduce a computer worm to the mainframe in Fukushima Dai-Ichi, and only requires a humble thumb drive. Discover for yourself who was doing the security at Fuku Dai-Ichi up until two weeks before the 'accident.'
For stuxnet to be effective it requires a human operator to tweak the specific program to cause the damage that whoever it is that arranges such things desires. Stuxnet is designed to be undetected and it is intended to become active when there is a situation where an emergency response is required. Stuxnet's purpose is to wreck an emergency response and create a disaster out of a problem. It typically alters the 'clock' in the systems and causes motors to stop, change speed or overspin to destruction - whatever is most effective for the watcher.
All water under the bridge now.
