First U.S. nuclear reactor built from scratch in decades enters commercial operation in Georgia::ATLANTA — A new reactor at a nuclear power plant in Georgia has entered commercial operation, becoming the first new American reactor built from scratch in decades.
What’s the normal amount of over budget and behind schedule?
Ideally zero? But given this is the first US reactor in decades, it is by definition normal I suppose.
That would be ideal, but people always underestimate the cost and difficulty of things.
Those amounts there. For comparison for example another recent plant Olkiluoto 3 in Finland was 13 years late on a 5 year original construction timeline (18 years total construction time) and
108 billion euros over budget on original budget of 3 billion euros. (Final estimate it cost constructor13-1411 billion euros to build. Technically its fixed price contract so customer price is still 3 billion. However it did bankrupt the builder Areva and litigations are ongoing about, if the French can extract more money from he customer TVO)So doubling the price budget and doubling the build time is not at all unreasonable first estimate on the announced numbers of the builder and customers at start of project.
