ACTUATION OF CONTAINMENT SPRAY SYSTEM
"On October 2, 2019, at 0415 EDT, with Unit 2 in Mode 5 at 0 percent power, an actuation of the Unit 2 containment spray system occurred during valve strokes of the 2A train containment spray header isolations while the 2B train containment spray pump was in recirculation. The reason for the containment spray actuation was due to a conflicting procedural alignment with the 2B containment spray recirculation procedure. The containment spray system does not have an automatic function, and only receives manual actuation. The Unit 2 containment spray actuation was secured at 0416.
"This event is being reported in accordance with 10 CFR 50.72(b)(3)(iv)(A) as an event that results in a valid actuation of the containment spray system.
"There was no impact on the health and safety of the public or plant personnel.
"The NRC Resident Inspector has been notified."
