be evaluated to ensure that performance requirements are correctly and completely included. • Clause 5.4.4, “Implementation V&V Activity,” (7) “Component V&V Test Execution and Validation” - components shall be evaluated to assure that the implementation, including performance, satisfy the design. • Clause 5.4.5, “Test V&V Activity” - integration, system, and acceptance testing shall be carried out, including performance aspects. • Various clauses require that requirements, including performance requirements, be traced from requirements through design, implementation, and testing. Annex G (informative) as modified by Regulatory Position 7 of RG 1.168, “Optional V&V Task Descriptions” - various tasks are described, including: - Performance monitoring - performance information is continually collected and analyzed under operational conditions to assure that system and software performance requirements are satisfied. - Sizing and timing analysis - data about the software functions and resource utilization is collected and analyzed to determine if system and software requirements for speed and capacity are satisfied. RG 1.105, “Setpoints for Safety-Related Instrumentation,” endorses ISA-S67.04, Part 1, “Setpoints for Nuclear Safety-Related Instrumentation,” as an acceptable method for initially setting and maintaining instrument calibrations in nuclear reactor I&C systems in order to assure their proper response on demand. System time delays are an important consideration in establishing instrument setpoints. Additional guidance on the application of RG 1.105 is provided by SRP BTP 7-12, “Guidance on Establishing and Maintaining Instrument Setpoints.” In addition to the above, NUREG/CR-6082 describes data communication systems, including aspects related to system performance and timing. NUREG/CR-6083 describes real-time systems with respect to performance, timing, and complexity. These documents include detailed guidance for reviewing
