| event text = McGuire Unit 1 and Unit 2 may have been operating greater than design thermal power limits of 3411 MW [Megawatt] by approximately 0.08% due to discovery of non-conservative thermal power calculations. Preliminary evaluation of Steam Generator Blow Down inputs into the thermal power calorimetric indicates a non-conservative error resulting in indicated total thermal power being approximately 0.08% lower than actual. Additional evaluations to confirm indicated power are ongoing. Power was reduced as soon as the on duty shift was made aware of the error and both Unit 1 and Unit 2 indicated thermal power is being limited to less than 99.85% to ensure actual reactor power remains less than 3411 MW. | | event text = McGuire Unit 1 and Unit 2 may have been operating greater than design thermal power limits of 3411 MW [Megawatt] by approximately 0.08% due to discovery of non-conservative thermal power calculations.
