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 information systems important to safety satisfy the requirements of the acceptance criteria and guidelines applicable to these systems, and that they will provide the information to ensure plant safety during all plant conditions for which they are required. The specific areas of review are as follows: 1. This Standard Review Plan (SRP) section describes the review process and acceptance criteria for those instrumentation and control (I&C) systems that provide information to the plant operators for (1) assessing plant conditions, safety system performance and making decisions related to plant responses to abnormal events, and (2) preplanned manual operator action related to accident mitigation. The information systems reviewed using this section also provide the necessary information from which appropriate actions can be taken to mitigate the consequences of anticipated operational occurrences. The systems reviewed using Section 7.5 of the SRP include the following: 1For the purposes of this section, the annunciator system is considered to consist of sets of alarms (which may be displayed on tiles, video display units, or other devices) and sound equipment; logic and processing support; and functions to enable operators to silence, acknowledge, reset, and test alarms. 7.5-2 Revision 5 - March 2007 • Accident monitoring instrumentation. • Bypassed or inoperable status indication (BISI) for safety systems. • Plant annunciator (alarm)1 systems. • Safety parameter display system (SPDS). • Information systems associated with the emergency response facilities (ERF) and Emergency Response Data System (ERDS). For SPDS, ERF, and ERDS, the organization responsible for the review of I&C limits its review to the system interface with the plant control and safety systems.
