A reactor at the Browns Ferry Nuclear Plant is operating at only partial power after an unplanned shutdown.
A report filed by the Tennessee Valley Authority says the Unit 2 reactor shut down unexpectedly on Saturday. The reactor was going through testing after maintenance at the time. The federal utility says all the safety systems operated like they were supposed to. The plant's other two reactors weren't affected, and TVA says Unit 2 was producing power at 19 percent of its capacity on Wednesday morning.
Warren Buffett's company says it sold two short-line railroads it recently discovered it owned to satisfy regulators who might have reviewed Berkshire Hathaway's 2010 acquisition of the Burlington Northern Santa Fe railroad.
Berkshire told the Transportation Department's Surface Transportation Board earlier this month that it had recently completed the sale of both short-line railroads ahead of schedule. If Berkshire had reported owning those railroads when it bought BNSF, the Surface Transportation Board would have had to scrutinize the deal.
Buffett's Berkshare Hathaway owns Shaw Industries in Dalton, Ga., and Clayton Homes in Knoxville.
