Miami Herald: Outer shield of new reactors could shatter like a ‘glass cup’ -NRC lead reviewer

Miami, Oct. 16 –Headline: ‘Fukushima disaster can happen here’ Today’s Miami Herald has an article warning South Florida residents they “should take little comfort in assurances that a Fukushima-type catastrophe could not happen here.” It notes that the Miami-area nuclear power plant, Turkey Point, “is just as reliant as Fukushima on offsite electricity, emergency electrical generators and batteries.”

Yet, Florida Power & Light (FPL) is trying to build two new reactors at the site, making a total of four.

These two proposed reactors, the AP1000 design, are essentially “experimental” and “have never been tested or operated commercially at full scale”.

The reactor design has “drawn substantial criticism on safety issues”. The article reviews three of these:

1) “One major issue is that the steel inner-containment structure is barely strong enough to keep radioactivity from escaping during a ‘design basis accident.’ This leaves little margin for error when the steel containment structure eventually corrodes and loses strength. Such corrosion is a common problem in older reactors.”

2) “The British Nuclear Installations Inspectorate has criticized Toshiba/Westinghouse for not sufficiently demonstrating that the outer concrete shield can withstand an external shock, such as an earthquake, hurricane, tornado or impact from a commercial aircraft crash.”

3) “Perhaps, the most damaging criticism comes from Dr. John Ma, the lead structural reviewer evaluating the outer concrete shield for the U.S. Nuclear Regulatory Commission (NRC). Dr. Ma submitted a ‘nonconcurrence statement of dissent’ stating that the outer shield could shatter like a ‘glass cup’ in an earthquake or commercial aircra
