rocedures, and analytical results, (2) engineering information for the installed instrumentation, (3) supporting analyses, and (4) requirements and operating history 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: • The facility setpoint list identifying safety and non-safety setpoints. • A description of the setpoint methodology and procedures used in determining setpoints, including information sources, scope, assumptions, interface reviews, and statistical methods used. • Terminology used to describe limits, allowances, tolerances, and environmental or other effects used to support setpoint calculations. • The technical specifications and the basis for limiting safety system settings (LSSS). • The basis for calibration intervals. • The basis for assumptions regarding instrument uncertainties and a discussion of the method used to determine uncertainty values. • A description of the provisions for control of measuring and test equipment used for calibration of the instrument. • A description of the program and methodology used to monitor and manage instrument uncertainties, including drift. Rev. 4 — June 1997 Appendix 7-A BTP HICB-12-4 A documented basis for safety system setpoint should be available for Staff review. Documentation should conform with the guidance of Draft Reg. Guide DG-1045. The description of the instrument channel required by ISA-S67.04 Part I should include: • A description of the functional and performance requirements for the initiation and execution of the safety functions initiated at the setpoints. • Instrument specifications, including range, accuracy, repeatability, hysteresis, dynamic response, environmental qualification, calibration reference, and calibration intervals should be listed for each instrument type. • Instrument loop diagrams showing all
