U.S. Nuke plants to enter digital age – soon

Just when I thought the U.S. nuclear industry couldn’t get more pathetically ridiculous than it already is, a news item today proudly announces that a nuclear reactor in South Carolina will become the first in the country to have digital controls installed on its safety and operating equipment.
Think about it.
The technology they’ve been using to ensure the safety of everyone around them is no more advanced than your grandfather’s wind-up alarm clock and slide rule.
Pilgrim Nuclear goes on “unplanned” shutdown
As long as we’re on the subject of safety, the Pilgrim Yankee Nuclear power plant in Plymouth suddenly shut down two weeks ago. The company would only say it was “operator error,” but couldn’t say how long it would stay shutdown. The Nuclear Regulatory Commission, meanwhile, said its sending a special investigative team to find out what happened, something that they’ve done only a handful of times before.
Seabrook concrete weakened by water seepage
Just up the coast from Plymouth is the Seabrook Nuclear plant in Seabrook, NH. A report issued last week found that groundwater was undermining the concrete housing of the cables that run the plant’s safety system. Leakage into the tunnels could short circuit the safety system. This was first discovered sometime last year, but not publicized until last week. No sense rushing things. The NRC is happy to report no danger to the public.
It might be useful to remember it wasn’t the earthquake that caused the meltdown at Fukashima, but water from the tsunami that short-circuited the backup safety system.
