More like 30% at least.

Paul, thanks heaps for your comments. Here’s the relevant part of Dr. Peterson’s comment on commodity inputs [he gives the references as well]:

While it is widely understood that nuclear energy costs have quite low sensitivity to the cost of uranium, it is not widely appreciated that the same applies to construction materials. If one takes the total quantity of steel, concrete, copper, and other materials required to build a light water reactor similar to those operating today [1], and then multiplies these quantities by the respective current commodity prices, the total contribution of commodity inputs is $36 per kilowatt of generation capacity [2], out of total construction prices that are estimated today to range from $3000 to $5000 per kilowatt today. The dominant cost of nuclear construction is instead in the added value that comes from converting these commodities into an operational nuclear power plant. Conversely, wind turbines require approximately a factor of 10 times as much steel and concrete to construct without considering storage capacity [3], and thus have construction costs that are sensitive to commodity costs and to potential future resource scarcity.

So he gave a range of 36/3000 to 36/5000 or 0.7% to 1.2%.

Can you educate us on the construction cost buildup — also on why quotes have gone up so much since 2000?
