I did a little google-driftnetting and found conflicting numbers, but all of them higher than the 2:1 number which I, as well as you, read sometime back from some fairly reputable source (which is why it stuck in my mind).  I see numbers as high as 20:1 (obviously from industry sources) and others in the 12-16:1 ballpark, obviously far superior to the 2:1 ratio.  OTOH wind turbines were rated in one paper at 37:1 (!) which is food for thought indeed.

I had better stop citing that 2:1 number and do some more homework.  will try to rediscover where that number came from.  I wonder if it was the result of factoring in decommissioning costs, i.e. they are not decoupled from this number as I had thought.  

I did come across the interesting tidbit that "The wet storage at Yankee Rowe costs $5 million a year" -- a tidy annual payment on those hot spent rods... well I have a spare-time hobby for the next couple of days I guess, sourcing and attributing EROEI figures for various generations of nuke plant :-)

The difference between theory and practise in practise ...
