REVIEW RESPONSIBILITIES Primary - Organization responsible for the review of instrumentation and controls Secondary - None 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 Standard Review Plan (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, 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 limits are not exceeded. The controls, inhibits, and interlocks for the withdrawal, insertion, and sequence of control rods are described in the safety analysis report (SAR) Sections 7.6 and 7.7. 7.2-2 Revision 5 - March 2007 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 has been reviewed against acceptance criteria contained in this SRP section. Furthermore, the staff reviews the ITAAC
