NRC inspects damage to nuclear reactor part, delayed reporting at Summer plant

Summer nuclear power expansion to cost $6.8bn, finish in 2019 & 2020

The U.S. Nuclear Regulatory Commission (NRC) begins special inspections on inadvertent damage caused at the V.C. Summer nuclear power plant in South Carolina.
 
During the week of Feb. 9, workers with Chicago Bridge & Iron (CB&I, NYSE: CBI) cut safety-related rebar and damaged the containment vessel bottom head while drilling into concrete. CB&I did not report the damage to plant operator SCANA until Feb. 16 and SCANA reported it to the NRC.
 
The NRC inspection team will spend about a week on site reviewing the events and both assessments from CB&I and SCANA as well as develop its own assessment.
 
“While the actual damage appears to have been minor, we want to make sure we completely understand its potential impact and the apparent breakdown in controls that might have prevented it,” said NRC Region II Administrator Victor McCree. “We are also concerned about the delay in CB&I reporting the issue.”
 
The Summer site has one unit in operation and two others currently under construction. The two Westinghouse AP1000 reactors are scheduled for completion in 2019 and 2020.
