WTVD, the ABC affiliate in Raleigh, North Carolina, reported today:
Inspectors at the Duke Energy Shearon Harris nuclear power plant have found a flaw in a reactor vessel for the second time this year. The vessel contains the plant’s nuclear fuel.
A report filed with the Nuclear Regulatory Commission says “ultrasonic examinations identified a flaw in a head penetration nozzle” of the vessel. The report says the problem was discovered November 18.
Coincidentally, I received a notification today from the Nuclear Regulatory Commission:
The U.S. Nuclear Regulatory Commission (NRC) is issuing this information notice (IN) to inform addressees of examples of welding problems that occurred during the fabrication of reactor plant components.
The notification cited example from a French reactor and two reports from the Vogtle nuclear power plant in Georgia.
