Japan/World Nuclear cooling methods.?

Japan/World Nuclear cooling methods.? Topic: Use case system engineer
June 16, 2019 / By Jervis
Question: I am wondering why the methods used to cool those reactors failed?? From what I understand there are "back up" systems (generators) used to cool the system but they failed. I am not a nuclear engineer but if they use some sort of generators to run cooling pumps wouldnt they be "stand alone self sufficient" models that start and run on batteries and not electricity in case of electric power loss. This just seems like common sense to avoid the problems they are having now????

Back up systems still have to deal with pipes and electrical circuits that were damaged by the earthquake and shorted by the tsunami.

The tsunami flooded the generators and the backup batteries were only designed to power the pumps for about 16 hrs.

Actually.. to the dude below me.. It's not God's will.. everyone has free will.. they went against God's will.. that is why it happened

Brayden Originally Answered: Would a global cooling trend prove that CO2 is not a major climate driver?
"So my question is: if the current global cooling trend (or even a level temperature trend) keeps occurring, will this be enough evidence to disprove the CO2/temperature causation theory?" Could you specify what "keeps occurring" means? Periods of no wamring/slight cooling are well within the predictions of AGW. http://www.agu.org/pubs/crossref/2009/2009GL037810.shtml http://greenhome.huddler.com/forum/thread/1354/is-global-climate-warming-or-cooling for a brief discussion. "In other words, while we still may not know the exact nature of global temperature trends, we can reliably put CO2 as a minor factor?" Define minor and explain why this would be so. My response would be there's not enough information from what you have provided to "reliably" put CO2 anywhere. Edit: "So if solar minimum and a cool PDO phase cause level or cooling temperatures for several decades, I would expect that we can conclude that CO2 is not as strong as we thought it was." I wouldn't necessarily agree with that. I think scientists have a very good grasp of how strong CO2 is. An unusually long or deep solar minimum combined with a cool PDO phase for several decades would not alter the strength of CO2.
