FPL reports Turkey Point Unit 3 nuclear containment liner corrosion to NRC

Source: U.S. Nuclear Regulatory Commission

In a report filed with the U.S. Nuclear Regulatory Commission (NRC) on Monday, Florida Power & Light (FPL) employees found what was described as a condition resulting in a serious degradation of the Containment liner during a visual inspection at the Turkey Point Nuclear Generating Unit 3 in South Miami.

FPL workers first detected corrosion in the containment sump liner of Turkey Point Unit 3 during routine inspections being conducted as a part of a scheduled refueling at the facility. A more detailed inspection was conducted Sunday after the damaged area of the liner was cleaned; revealing that the hole exceeded corrosion levels permitted by the ASME Code and would require repairs. The licensee notified the NRC Resident Inspector, filing the event with the regulatory commission Monday.

At the time of the filing, it had not been determined whether any leakage caused by the through-wall condition would have resulted in exceeding the allowed leakage level limit for the containment. 

Turkey Point Nuclear Generating Unit 3 is a 720-megawatt pressurized water reactor that began commercial operations in 1972 and received approval in 2002 from the NRC to extend its operating license through 2032.
