ss parameters. These analytical limits, as established by accident analyses, do not normally include considerations for the accuracy (uncertainty) of installed instrumentation. Additional analyses and procedures are necessary to assure that the limiting trip setpoint of each safety control function is appropriate. BTP 7-12-5 Revision 5 - March 2007 Instrument channel uncertainties in these analyses are based on the characteristics of installed instrumentation, the environmental conditions present at the instrumentation's installed locations, and process conditions. A properly established setpoint initiates a plant protective action before the process parameter exceeds its analytical limit. This, in turn, assures that the transient will be avoided and/or terminated before the process parameters exceed the established safety limits. Similar calculations and reviews are performed as necessary to verify the setpoints for functions that are not related to a safety limit or for non-safety systems or procedural action points for safety and non-safety systems. 2. Information to Be Reviewed The information to be reviewed consists of (1) a description of the setpoint program, procedures, and analytical results, (2) engineering information for the installed instrumentation, (3) supporting analyses, and (4) provisions and operating history, if available, for the instrument maintenance and calibration program. 3. Acceptance Criteria Setpoint Documentation The following information on the licensee/applicant's setpoint program should be provided for review: • Facility setpoint list identifying safety setpoints and non-safety setpoints for functions providing protective functions important to safety or that are relevant to compliance with technical specification limiting conditions for operation. • Identification of safety setpoints that are not safety-limit-related LSSS and the basis for this determination. • Identification of setpoints that trigger procedural actions that
