REVIEW RESPONSIBILITIES Primary - Organization responsible for the review of instrumentation and controls Secondary - None Review Note: The revision numbers of Regulatory Guides (RG) and the years of endorsed industry standards referenced in this Standard Review Plan (SRP) section are centrally maintained in SRP Section 7.1-T, “Regulatory Requirements, Acceptance Criteria, and Guidelines for Instrumentation and Control Systems Important to Safety,” (Table 7-1). Therefore, the individual revision numbers of RGs (except RG 1.97) and years of endorsed industry standards are not shown in this section. References to industry standards incorporated by reference into regulation (IEEE Std 279-1971 and IEEE Std 603-1991) and industry standards that are not endorsed by the agency do include the associated year in this section. See Table 7-1 to ensure that the appropriate RGs and endorsed industry standards are used for the review. 7.7-2 Revision 6 - August 2016 I. AREAS OF REVIEW The objectives of the review are to confirm that the control systems conform to the acceptance criteria and guidelines so that the controlled variables can be maintained within prescribed operating ranges, and that effects of operation or failure of these systems are bounded by the accident analyses in Chapter 15 of the safety analysis report (SAR). The specific areas of review are as follows: 1. This SRP section describes the review process and acceptance criteria for those control systems used for normal operation that are not relied upon to perform safety functions following anticipated operational occurrences or accidents. The control systems covered by this SRP section include those control systems that control plant processes having a significant impact on plant safety. These control systems 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
