So why do they get the costs wrong? The Channel Tunnel Rail Link was
built on-time and on-budget. Why is the civil nuclear industry unable
to make as good an estimate of time and cost as the rest of civil
engineering?

I meant that nobody knows how much it costs to *build* the power
station; nobody cares what disposal and storage costs are because
governments pick up the tab on that.

After fifty-odd years, we should have an idea of the cost of building
a power station---we don't. We *do* have a good estimate of what it
costs, and how long it takes, to put up a wind turbine.

Enrico Fermi. Although I wouldn't have liked to be there.

I thought the Tunnel and associated rail links went hugely over time and
budget and have struggled to survive as a result?

And Polish highways are notoriously late and over budget. :-)

Do you claim that _all_ civil engineering projects except nuclear
engineering
are always on time and within budget?

Some civil engineering projects are on time and within budget, but then
again, so are some nuclear power plants.

This is patently false. Nobody can be sure how much it costs to
build _some_ power stations. Just like with every large scale
engineering projects.

In case of wind turbines what we don't know is what the power is going
to cost in the long run. What will be the influence of giant wind turbine
farms on weather patterns? Paving the earth with wind turbines with
an output comparable to nuke plants could have some repercussions, and
a change in weather patterns could drive the cost of power upwards by
a significant amount.

BTW, do you have some sources that show that wind turbines are never
over budget and late? :-) Because it seems a bit suspicious, claiming
that one kind of civil engineering projects is immune to problems
with scheduling and budgeting.

Quick googling shows one project for a wind turbine that ended up
costing 1 million USD, while the budgeted cost was 600 thousand USD.
Well, it's only 65% over budget or so, so you're quite right, it's
almost like it was built within budget. Not. :-))

Only 80% over budget or so, according to the wikipedia.

So, almost not like nuclear power plants. ;-)
