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 are important to safety. • Description of the setpoint methodology and procedures used in determining setpoints, including information sources, scope, assumptions, interface reviews, and statistical methods. • Terminology used to describe limits, allowances, and tolerances, and environmental or other effects used to support setpoint calculations. • Technical specifications and basis for LSSSs. • Basis for acceptable as-found band and acceptable as-left band and determination of the instrument operability based on acceptable as-found band and acceptable as-left band. • Basis for calibration intervals. BTP 7-12-6 Revision 5 - March 2007 • Basis for assumptions regarding instrument uncertainties and a discussion of the method used to determine uncertainty values. • Description of the provisions for control of measuring and test equipment used for calibration of the instrument. • Description of the program and methodology used to monitor and manage instrument uncertainties, including drift. A documented basis for safety system setpoint should be available for Staff review. Documentation should conform with the guidance of Regulatory Guide 1.105, Revision 3. The description of the instrument channel in accordance with ISA-S67.04-1994, Part I, should include: • Description of the functional and performance criteria for the initiation and execution of the safety functions at the setpoints. • Instrument specifications, including range, accuracy, repeatability, hysteresis, dynamic response, environmental qualification, calibration reference, and calibration intervals for each instrument type. • Instrument loop diagrams showing all hardware elements of the instrument loop(s). • Instrument and tubing layout drawings and installation details showing
