Attachment I describes the setpoint methodology for the RPS while Attachment 2 describes the methodology for Balance-of-Plant equipment including the ESFAS. These documents provide the information necessary for your Staff to complete their review of Confirmatory Item (15) of the Midland Safety Evaluation Report.
As indicated in the attached documents, the method used in determining setpoints in the RPS and ESFAS provides sufficient margin between the trip i
setpoints and appropriate safety limits to account for accuracies, drift, uncertainties and dynamic responses. This methodology thus provides assurance that RPS and ESFAS trips will occur when required to prevent exceeding l
appropriate safety limits.
