The Turkey Point nuclear power plant is undergoing a special inspection to assess how and why the facility had a brief loss of the intake cooling water function at one of the plant’s two nuclear units, Nuclear Regulatory Commission (NRC) officials said.
Turkey Point Unit 3 lost the function of the intake cooling water system for about 20 minutes Aug. 11 when an open valve closed and then failed in that closed position.
The intake cooling water system provides cooling to important plant equipment. NRC staff determined because the failure resulted in the loss of a safety system and because there is also a potential generic concern, a special inspection was appropriate.
The NRC special inspection team consists of two inspectors as well as an acting resident inspector already at the Turkey Point plant. The team will develop a timeline and review Florida Power & Light’s (FPL) response, assess the plant’s ability to meet its design functions, review maintenance and testing performed for the valve, and assess the company’s problem investigation activities.
The on-site portion of the inspection will wrap this week, and a report documenting the results should ready to go within 45 days of the completed inspection.
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.
