An anonymous reader quotes a report from CNN: The Tennessee Valley Authority is celebrating an event 43 years in the making: the completion of the Watts Bar Nuclear Plant. In 1973, the TVA, one of the nation’s largest public power providers, began building two reactors that combined promised to generate enough power to light up 1.3 million homes. The first reactor, delayed by design flaws, eventually went live in 1996. Now, after billions of dollars in budget overruns, the second reactor has finally started sending power to homes and businesses. Standing in front of both reactors Wednesday, TVA President Bill Johnson said Watts Bar 2, the first U.S. reactor to enter commercial operation in 20 years, would offer clean, cheap and reliable energy to residents of several southern states for at least another generation. Before Watts Bar 2, the last time an American reactor had fired up was in 1996. It was Watts Bar 1 — and according to the Atlanta Journal-Constitution, it cost $6.8 billion, far greater than the original price tag at $370 million. In the 2000s, some American power companies, faced with growing environmental regulations, eyed nuclear power again as a top alternative to fossil fuels such as coal and oil. A handful of companies, taking advantage of federal loan guarantees from the Bush administration, revived nuclear reactor proposals in a period now known as the so-called “nuclear renaissance.” Eventually, nuclear regulators started to green light new reactors, including ones in Georgia and South Carolina. In 2007, the TVA resumed construction on Watts Bar 2, according to the International Atomic Energy Agency. The TVA originally said it would take five years to complete. The TVA, which today serves seven different southern states, relies on nuclear power to light up approximately 4.5 million homes. Watts Bar 2, the company’s seventh operating reactor, reaffirms its commitment to nukes for at least four more decades, Johnson said Wednesday. In the end, TVA required more than five years to build the project. The final cost, far exceeding its initial budget, stood at $4.7 billion. Read more of this story at Slashdot.

First New US Nuclear Reactor In 20 Years Goes Live
Microsoft announced today that Windows 10 is now running on over 400 million active devices. This is up from 300 million as of May, and 207 million as of end of the March. The company says that it deems devices that have been active in the past 28 days as “active.” Microsoft added that this 400 million active devices figure include tablets and phones as well as Xbox One consoles, HoloLens, and Surface Hubs running Windows 10. Paul Thurrott adds:Microsoft last provided a Windows 10 usage milestone on June 29, when it said that there were 350 million active Windows 10 devices. At that time, I noted that the Windows 10 adoption had accelerated from the previous milestone, hitting an average of almost 29 million new devices per month. But 50 million additional devices over three months is a much slower pace of about 17 million per month. This is the slowest rate since Windows 10 was first announced. Again, no surprise there: Windows 10 was free for its first year, and over that time period it averaged roughly 31.25 million new devices per month (if you assume a figure of 375 million after one year, as I do). Does this mean that Windows 10 will see fewer than 20 million new devices each month, on average, going forward? No, of course not. There’s no way to accurately gauge how things will go, given that most future devices will be new PCs purchased by businesses or consumers, or business PCs upgraded to Windows 10.
