The Brown’s Ferry nuke plant in Alabama, is under investigation by the Nuclear Regulatory Commission.  Investigators say a cooling system failure is of “high safety significance”.

Last October the plant had a cooling valve problem, in reactor 1, that cause it to shut down.  Operators say the valve is fixed.  But there are concerns especially since the Brown’s Ferry plant is similar to the GE designed Fukushima Daiichi plant in Japan.

Also, Brown’s Ferry Reactor 1 had been shut down for 22 years before being put back into operation in 2007.
