Steel plates sent to Plant Vogtle fail NRC inspections, The Augusta Chronicle, By Rob Pavey Staff Writer, Sept. 20, 2012 At least 211 steel plates built for use in Plant Vogtle’s new reactors failed inspections by the U.S. Nuclear Regulatory Commission.

The plates, or “embedments,” are structural strengthening components
that can be encased in concrete and have protruding steel rebar to
which other materials can be attached.
According to an NRC event notification dated Thursday, inspectors
found “noncompliances and deviations” in the material, which had been
received from Cives Steel Co., of Valdosta, Ga., but had not yet been
used in reactor construction.
“Examples of the types of deviations identified include unacceptable
welds and weld repairs, missing Nelson studs, damaged Nelson studs,
improper painting, incorrect dimensions, and illegible markings for
identification,” the document said.
The embedments were part of a shipment that included 892 plates, with
an average size of 18 by 18 inches. The embedments can be used in
walls and floors.
A more detailed investigation to determine the extent of the problem –
and any potential effect on the project – will be completed by Nov. 6….
