fellow Posted March 13, 2011 Share Posted March 13, 2011 they are loosing their residual heat and some of them have melted or will melt into the containment ... no disaster; just reactors written off ... You think that a former nuclear power plant designer's opinion is 'simply wrong'? You can see what is happening inside the reactors from where you are sat? 'loosing'?

Damik Posted March 13, 2011 Share Posted March 13, 2011 a/ if the cooling system is working as normal then the situation is no different to any fully working nuclear reactor... b/ if there is no cooling it will melt through the container. c/ indeed they have even stated they are pumping sea water into the container in an effort to cool it. b/ nonsense c/ yes, but it does not mean that it can burn through the containment at all more here: http://en.wikipedia.org/wiki/Nuclear_meltdown Quote Link to comment Share on other sites More sharing options...
Scott Sando Posted March 13, 2011 Share Posted March 13, 2011 Don't you trust anonymous internet generals? I'm sure its coming from the right place, but I wouldn't be too sure of anything thats been said right now including what I'm writing.

Kashima lost a lot of arable land back to the sea, I wonder how much still flooded will remain that way around the affected areas. Quote Link to comment Share on other sites More sharing options...

The 'after' looks darker even in parts of the image where there's no apparent damage. Still manipulated Quote Link to comment Share on other sites More sharing options...

From your link. The fuel assemblies in a reactor core can melt if heat is not removed. A nuclear reactor does not have to remain critical for a core damage incident to occur, because decay heat continues to heat the reactor fuel assemblies after the reactor has shut down, though this heat decreases with time. You know that radioactive decay produces heat, don't you? Quote Link to comment Share on other sites More sharing options...
interestrateripoff Posted March 13, 2011 Share Posted March 13, 2011 http://www.nytimes.com/2011/03/14/world/asia/14nuclear.html?_r=1&hp Japanese officials struggled on Sunday to contain a quickly escalating nuclear crisis in the aftermath of a devastating earthquake and tsunami, saying they presumed that partial meltdowns had occurred at two crippled reactors, and that they were bracing for a second explosion, even as problems were reported at two more nuclear plants. That brings the total number of troubled plants to four, including one that is about 75 miles north of Tokyo. Didn't realise it was 4 plants in total with issues.
