Coal Mining and Processing The National Academies Press

Although the United States has the vast coal resource described in the previous chapter, perhaps as much as 4 trillion tons, the key issue for policy makers is the amount of coal that is economically recoverable. This is not a fixed quantity, but depends on the geological resource, the market price, and the cost of mining.

COSTS OF NUCLEAR POWER PLANTS — WHAT WENT

But what about the "best experience" plants that avoided these horrendous cost escalations. For that matter there are many plants for which the costs were much higher than indicated by "median experience" data. Nuclear plant costs vary by large factors. Almost every nuclear power plant built in the United States has been custom designed.
