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. 7.2-2 Revision 6 – August 2016 I. AREAS OF REVIEW The objectives of the review are to confirm that the reactor trip system (RTS): (1) satisfies the requirements of the acceptance criteria and guidelines applicable to the protection system and (2) performs its safety functions for all plant conditions under which the safety functions are required. 1. This SRP section describes the review process and acceptance criteria for the RTS, which is part of the reactor protection system. The review process and acceptance criteria apply to all RTS equipment, including hardware, software, and firmware, from sensors to actuation devices (e.g., power sources, sensors, signal conditioners, initiation circuits, logic, bypasses, interlocks, racks, panels, control boards, interconnections, and actuation devices) that are required to initiate reactor shutdown, and auxiliary supporting features and other auxiliary features. The RTS is designed to initiate the reactivity control system (control rods) automatically to ensure that specified acceptable fuel design
