Content:
ch emergency procedures will require operator action, determining the setpoint for interlock functions, and determining setpoints for control functions provided to maintain plant variables and systems within prescribed operating ranges. Therefore, the guidance of Draft Reg. Guide DG-1045 is useful in reviewing all I&C systems important to safety even if no automatic trip functions are involved. h. Regulatory Guide 1.118, "Periodic Testing of Electric Power and Protection Systems," (Endorses IEEE Std 338, Standard Criteria for the Periodic Surveillance Testing of Nuclear Power Generating Station Safety Systems") Applicability — All I&C safety systems, diverse instrumentation and control systems, and supporting data communication systems. Review Methods — Reg. Guide 1.118 provides a basis for evaluating conformance to GDC 21 and ANSI/IEEE Std 279, Section 4.10. The HICB evaluation is limited to the review of testing of protection systems. The evaluation of testing of electric power systems is addressed by others in the review of Chapter 8 of the SAR. BTP HICB-17 discusses periodic test provisions in digital computer-based systems. i. Regulatory Guide 1.151, "Instrument Sensing Lines," (Endorses ANSI/ISA-S67.02, "Nuclear Safety-Related Instrument Sensing Line Piping and Tubing Standard for Use in Nuclear Power Plants") Applicability — I&C sensing lines and sensing line environmental control systems. Review Methods — Reg. Guide 1.151 provides a basis for evaluating conformance to GDC 13. Environmental control systems for all I&C systems are addressed in the review of Section 7.7 of the SAR. j. Regulatory Guide 1.152, "Criteria for Digital Computers in Safety Systems of Nuclear Power Plants," (Endorses IEEE Std 7-4.3.2,"IEEE Standard for Digital Computers in Safety Systems of Nuclear Power Generating Stations") Applicability — All instrumentation and control safety systems and supporting data communication systems. Review Methods — Reg. Guide 1.152 provides a
