Georgia Nuclear Plant Begins Splitting Atoms For First Time (apnews.com) 257

Posted by BeauHD from the energy-of-the-future dept.
An anonymous reader quotes a report from The Associated Press: A nuclear power plant in Georgia has begun splitting atoms in one of its two new reactors, Georgia Power said Monday, a key step toward reaching commercial operation at the first new nuclear reactors built from scratch in decades in the United States. The unit of Atlanta-based Southern Co. said operators reached self-sustaining nuclear fission inside the reactor at Plant Vogtle, southeast of Augusta. That makes the intense heat that will be used to produce steam and spin turbines to generate electricity.

A third and a fourth reactor were approved for construction at Vogtle by the Georgia Public Service Commission in 2009, and the third reactor was supposed to start generating power in 2016. The company now says Unit 3 could begin commercial operation in May or June. Unit 4 is projected to begin commercial operation sometime between this November and March 2024.

The cost of the third and fourth reactors was originally supposed to be $14 billion. The reactors are now supposed to cost more than $30 billion. That doesn't include $3.68 billion that original contractor Westinghouse paid to the owners after going bankrupt, which brings total spending to more than $34 billion. Georgia Power said Unit 3 would continue startup testing to show that its cooling system and steam supply system will work at the intense heat and pressure that a nuclear reactor creates. After that, operators are supposed to link the reactor to the electrical grid and gradually raise it to full power.

With a reasonable, non-commercial 4% interest rate, the present value of annuity factor [wikipedia.org] converges to 25 years for an infinitely long depreciation horizon. (It's 23.9 years for 80 years of horizon). So it does not really matter that much whether the plant is going to last 40, 60 or 80 years to calculate the LCOE.

            This is because you need to pay interest for those loans you took to build the plant to begin with. No one is going to give you 30 billion dollars interest-free, except for the government, but then we are in subsidised territory and taxpayers will be paying for that.

      • > Nuclear produces zero carbon emission

        So long as you don't include the colossal amounts of carbon emitted during construction, then it's lower carbon during running, but "zero carbon" is highly debatable.

    • Solar was too expensive when the reactors were approved in 2009. In the mean time, the reactor cost doubled, and solar fell like a rock. So now nuclear is too expensive.

      The US southeast has basically no wind power, because trees and hills slow down low-level winds. That's why most wind is in the flat middle part of the country, and soon to be offshore.

      • Solar was too expensive when the reactors were approved

        The decision to build the reactors was reasonable at the time. Solar and wind were still expensive, and there was reason to believe that the standardized AP1000 design would cut costs and speed construction.

        Today, solar and wind are far cheaper, and it is clear that the AP1000 is a disaster.
