"Life shrinks or expands in proportion to one's courage." - Anaïs Nin

What I notice in this report is that they don't really estimate the external costs of nuclear. What they write is the the estimates in the literature lie in the (enormous) range between 0.1 and 270 cents/kWh. And as they see no methodically valid way to pick a plausible value from this, they settle on conventionally using the value for the most dirty of the fossil fuels, lignite at 7.9 ct/kWh.

But, hey, this isn't methodologically valid either!

Using the most optimistic (and likely wrong) value, nuclear comes out at 5.0 ct/kWh, below wind and water -- but only slightly. Using the most pessimistic (and likely wrong too) value, nuclear goes off the scale.

A loose end in an otherwise interesting report. (What I would have done is take the median of literature values: this would be somewhat robust against both the unduly optimistic and unduly pessimistic results.)
