Design flaws in America’s nuclear reactors: NRC engineers call for shutdown, if not fixed
NRC engineers urge shutdown of nuclear plants if design flaw not fixed, Utility Dive By Robert Walton | March 3, 2016
Dive Brief:
- A group of engineers in the U.S. Nuclear Regulatory Commission say they have identified a design flaw in nearly all nuclear reactors in the country that should result in their mandatory shutdown unless operators fix the problem, Reuters reports.
- In late February, the engineers petitioned the NRC to order immediate enforcement actions to correct the design flaw, which they say could result in damage to cooling systems and ultimately lead to an emergency situation. The filing asks the agency to respond by March 21 and is a part of a standard NRC process, according to the news outlet.
- The filing stems from an incident in January 2012, when Exelon’s Byron 2 unit in Illinois experienced an automatic reactor trip from full power after an undervoltage condition was detected. The unit was shut down for a week, in what is known as an open phase condition created by an unbalanced voltage. The NRC engineers say such an event could cause an electrical short, reducing the abilituy of cooling systems to operate.
Dive Insight:
In a little-noticed public filing, a group engineers from within the NRC are calling for an investigation into the nuclear vulnerability, and why it has not been fixed when the issue has been known since Exelon’s 2012 event.
Union of Concerned Scientists nuclear expert Dave Lochbaum told Reuters the agency “snatched defeat from the jaws of victory,” with its failure to address the issue after it became known in 2012. And the engineers say there has been at least 13 open phase events over the past 14 years.
Lochbaum said it was a positive sign the engineers filed, indicating no fear of reprisals. But the issue means “something is not right with the safety culture at the agency.” ……..http://www.utilitydive.com/news/nrc-engineers-urge-shutdown-of-nuclear-plants-if-design-flaw-not-fixed/414919/#.VthYQXYJX1Y.twitter
