>We tried four reactors back then, using a new regulatory process that was supposed to speed construction and reduce costs. Instead, costs and timelines ballooned 3x. Two of the four reactors were abandoned half-way through construction, resulting in rate payers holding the bag for billions of dollars and no Wh delivered to the grid. These were the Westinghouse AP1000 units to be installed in Georgia and South Carolina, contract beginning in 2008. It's worth noting that four other AP1000 units also from Westinghouse were built and installed in China, beginning construction in 2009 and entering into operation in 2018. The total cost of both systems was slightly more than half the cost of the failed project in South Carolina. >And construction productivity has stagnated since the 70s, while manufacturing productivity has gone through the roof. You seem to be arguing that we shouldn't bother building major projects, but I think this implies the opposite: we need to find ways to fix the construction industry. The US is currently facing a situation where cities can't grow like they used to; growing cities quickly become unaffordable, where by contrast Chicago sustained rapid growth for decades before the Great Depression.
