Browns Ferry Nuclear Plant:: River Water Too Hot To Cool One Unit

Well, now, here's a disaster waiting to happen; one we hadn't even thought of, yet.

The more we read about Climate change, look at the places around the world that are really heating up, the more we are convinced that 8 years of Bushite-corporate rule has made it impossible to hope for anything but a less hard landing.

Mother Earth is getting ready to to shake the fleas from her body.

ATHENS, ALA. — The Tennessee Valley Authority shut down one of three units at the Browns Ferry nuclear plant Thursday because water drawn from a river to cool the reactor was too hot, a spokesman said.

The nation's largest public utility shut down Unit 2 about 5:42 p.m. CDT because water drawn from the Tennessee River was exceeding a 90-degree average over 24 hours, amid a blistering heat wave across the Southeast.

"We don't believe we've ever shut down a nuclear unit because of river temperature," said John Moulton, spokesman for the Knoxville, Tenn.-based utility.

He said TVA would compensate for the loss of power by buying power elsewhere. The utility announced earlier Thursday that it was imposing a fuel surcharge on customers because of lower hydroelectric power production caused by drought conditions.

Two other units at the plant were operating, as well as towers to cool the water. But searing temperatures and a lack of cooler water in the upper part of the Tennessee River system made it too difficult to provide cool water for all three reactors. There was no safety threat posed by the shutdown.

Moulton said the average high temperature Thursday was 103 for five of the largest cities in TVA's coverage area: Huntsville and Knoxville, Chattanooga, Memphis and Nashville in Tennessee.

"It's the hottest in 20 years," he said.

He would not estimate when the unit would go back on line, saying it will depend on the weather.

"Temperatures are supposed to moderate some, but it will take a while for the river temperature to do that, too," Moulton said.

He said demand for TVA power set a record Thursday but the figures would not be available until Friday. The old record was 33,344 megawatts set last Wednesday.

TVA gets about 60 percent of its electricity from coal-fired power plants, 30 percent from nuclear plants and 10 percent from its 29 hydroelectric dams. Renewable energy sources such as wind and solar account for less than 1 percent.

TVA, the country's largest public utility, supplies electricity to about 8.7 million consumers across an 80,000-square-mile territory that includes most of Tennessee and parts of Alabama, Mississippi, Kentucky, Georgia, North Carolina and Virginia.

All three of the plant's reactors were mothballed in 1985 for safety reasons, but the other two units returned to service in the 1990s after extensive work.

The Unit 1 reactor, which is still online, was restarted in June after 22 years following a five-year, $1.8 billion renovation.
