Well, this is great and sounds good, but other that a pretty complete list of what utilities are affected, this is not very informative. All it says is that you have to address these 3 stages of the problem, but there is NO GUIDANCE on how to address them or what would constitute an acceptable solution. Typical of the NRC :-(

That was just the one document! There have been a series of documents released by the NRC addressing those issues. I think I have them somewhere. I'll see if I can find them all and upload them.

O.K., So I found the other supporting documents and I am posting all of them here. I have a sequence # at the beginning to roughly approximate the logical sequence in which they were released/developed.
