NEW HILL, N.C. — A flaw has been discovered in a reactor vessel at the Duke Energy Shearon Harris nuclear power plant for the second time this year, according to WTVD.
According to the report, a report filed with the Nuclear Regulatory Commission said “ultrasonic examinations identified a flaw in a head penetration nozzle” of the vessel.
The problem was discovered on Nov. 18 and the reactor was not in operation at the time. The reactor was shut down for refueling and the problem was discovered during a routine inspection.
The report states that the problem will be repaired prior to start-up from the refueling outage and said the structural integrity of the vessel had not been compromised.
The plant was temporarily shut down in May after a crack and early signs of corrosion were discovered in a reactor vessel.
