Apex Energy is evaluating the economics of building a 1000-megawatt nuclear power plant for $1.4 billion. The plant will have net revenue of $400 million per year and will operate for 30 years. At the end of the 30-year life, it will cost $3.5 billion to shut the plant down and dispose of the nuclear waste.
