ms are those systems that can, through normal operation, system failure or inadvertent operation, affect the performance of critical safety functions. Table 7.7 1 of this SRP section lists examples of control system functions that may be included in the scope of SRP Section 7.7 for boiling-water and pressurized-water reactors. The actual list of system functions and systems included in the scope of SRP Section 7.7 will be plant-specific. A specific plant may not necessarily incorporate all of the functions listed in Table 7.7-1, may require functions beyond those listed in Table 7.7-1, or may group functions into systems differently than indicated in Table 7.7-1. The organization responsible for the review of instrumentation and controls (I&C) also has secondary review responsibility for I&C portions of support systems and plant process systems. The acceptance criteria and review procedures of SRP Section 7.7 are also applicable to these other I&C systems. Table 7.7-2 of this SRP section lists examples of such control systems. Table 7.7-2 is not grouped according to plant type. The actual list of system functions and systems within the scope of the secondary review responsibility of the organization responsible for the review of I&C will be plant-specific. A specific plant may not necessarily incorporate all of the functions listed in Table 7.7-2, may require functions beyond those listed in Table 7.7-2, or may group functions into systems differently than indicated in Table 7.7-2. 2. Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC). For design certification (DC) and combined license (COL) reviews, the staff reviews the applicant’s proposed ITAAC associated with the structures, systems, and components (SSCs) related to this SRP section in accordance with SRP Section 14.3, “Inspections, Tests, Analyses, and Acceptance Criteria.” The staff recognizes that the review of ITAAC cannot be completed until after the rest of this portion of the application
