The "Cubic Mile of Oil"-numbers do show the opposite of what you are suggesting.
Replacing one CMU with nuclear is the second most expensive alternative, only solar panels are more expensive. Building 2200 nuclear power plant is not only totally out of question, it would also deplete world uranium reserves within a decade.
On the other Hand, building 1.6 Mio. wind turbines is the cheapest viable alternative. Germany alone already has about 22.000 of them, and they are profitable.
Safe nuclear power is not commercially viable. The only reason why it looks cheap is because today's commercial reactors are unsafe by design and the risk costs are carried by the society.
With the cheap nuclear reactors that are still being build today we will have a major nuclear disaster every 20-30 years, and the economic damage to the affected country is huge.
Depending on the outcome, Fukushima probably will cost Japan more than has ever been saved by using nuclear power at all. Expect Japan to pay billions every year just to maintain the Fukushima ruin, and this might go on for hundreds of years.
Just one Fukushima or Chernobyl type disaster in Germany would cost more than the transition to renewable sources.
Of course a society can make the decision to take the gamble, but Germany has been hit hard from Chernobyl Fallout - in some areas in Bavaria deer still can not be consumed because the meat is too radioactive, and it will take about 200 years until the situation will be normal.
The U.S. may not have such big problem when a few thousand square miles get polluted with radioactive fallout - the country is big.
For a small country like Germany, one nuclear disaster might cause more damage than World War II.
My guess is that within the next 30 years we will see another major nuclear disaster somewhere in the world, most probably in the U.S. or in France.
I also expect that most planned nuclear reactors never will get built because even before Fukushima they were too expensive, and after Fukushima no sane Investor will sink money into it.
Like about 80% of the german population I regard the decision to end nuclear power in Germany as a good one - not because I am afraid, but because it is an economically sound decision.
