Turkey Point Nuclear Generating Station, Unit 4, Renewed Facility Operating License 3.D, Fire Protection, stated that
Florida Power and Light (
FPL) shall implement and maintain in effect all provisions of the approved
fire protection program that comply with 10 CFR 50.48 (c), National Fire Protection Association (
NFPA) 805.
NFPA 805, Section 2.4.2.2.2 (b), Common Enclosure Circuits, required circuits that share a common enclosure with circuits required to achieve nuclear safety performance criteria shall be identified for their impact on the ability to achieve nuclear safety performance criteria. Contrary to the above, since 2014, the licensee failed to identify circuits that impact the ability to achieve nuclear safety performance criteria as a result of the effects of fire on circuits that share a common enclosure with the Unit 4
4kV switchgear. The violation was determined to be of very low safety significance based on risk evaluation provided by the licensee and reviewed by NRC senior reactor analyst. The licensee entered this issue into their corrective action program as action request 2134673.
