Maintenance personnel working in the vicinity of Moisture Separator Reheater 1B were setting up radiography equipment when the MSR 1B high level trip was generated. All rods fully inserted. Both Motor Driven Auxiliary Feedwater pumps actuated as expected. All Emergency Core Cooling Systems and the Emergency Diesel Generators are fully operable if needed. Catawba Unit 2 is operating at 100% power and the electrical grid is stable. | Maintenance personnel working in the vicinity of Moisture Separator Reheater 1B were setting up radiography equipment when the MSR 1B high level trip was generated.
