Since nuclear power plants are so expensive to build, even just the loss of plant itself is in the billions.

To put it in perspective, the prediction for the number of climate refugees vary, but papers seem to put the number somewhere between 150 and 300 million by 2050.[1]
That's about one Fukushima every five to eleven days, starting from now and continuing until 2050.
Think about it.

That's one Fukoshima every day.
Apparently the US felt that hundreds of thousands dead, millions displaced, and democratic governments overthrown was an acceptable price for slightly cheaper oil. I fully expect that calculation to come out the same when climate refugees are considered.
The lengths we'll go to for cheap energy and car culture, right?
Since I can't find it anymore I'll say that my number is very likely wrong and your's is right.
Sadly can't edit my post anymore though.
