I think the thing that bugs me here, as usual with this topic is the adversarial and somewhat ignorant nature of the debate. The original research that mdsolar spoke of, may well be accurate. But I don't see his condemnation of that research (as undermining the credibility of the Nuclear Regulatory Commission) based on the actual content. That's more a problem with mdsolar's point of view than with the NRC.
As to your current arguments, I find them a lot better quality.
