Consider a nuclear power plant operator working a morning shift (3am – 12pm) and an automated system that manages the plant. The automation integrates information from multiple places within the plant and provides alerts to the operator if there are values out of range. When the afternoon shift operator arrives at 12pm, they notice the temperature in reactor 1 is high and asks the morning operator how long the temperature has been rising. The morning operator replies that they have not received any alerts about the temperature in reactor 1 and was not aware that the temperature had been rising. The morning operator mentions that when they checked the temperature at 4am it was normal, and they were not aware it had changed. System diagnostics reveal that the temperature had been steadily rising since 5am but was not yet high enough to trigger an automated alert. Within hours, reactor 1 experiences a partial meltdown. What source of automation intervention failure is this describing?
