Nuclear unsafe? or is it human error?

Yet another article proving that the 3/11 Fukushima incident is not solely to be blamed on the often-cited unsafe nature of nuclear technology. The rebuttal here is that it is a 'man-made accident' . It would not have become the major catastrophe that it is known to be if not for the failure to adopt global safety standards that could have helped prevent the disaster. The problem is hence one that is based on human error rather than one due to the deficiency in the technology itself. Read the second article which I have posted before, which says the same thing of the Chernobyl incident.
Sample Qn: Is the pursuit of nuclear technology still desirable in today's world?
