I am wondering: how other sites would have classified exceeding DNB margin in reactivity management space.?
Details: The plant had tripped with the TCBs closed when the cold leg temperature was exceeded. The temperature was exceeded for less than 10 seconds. The Technical Specification action statement was met in the specified time. The event was originally graded as an incident.
Also, does your site consider the Tech Spec on DNB a reactivity management TS?
Thank you in advance!
