currences. The systems reviewed using Section 7.5 of the SRP include the following: • 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. Functional performance of those systems, as well as functional aspects of other I&C systems - such as radiation monitoring, fire detection, and the information systems for environs conditions during and following an accident - are addressed in the review of other sections of the safety analysis report (SAR). 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 to ensure that all SSCs in this area of review are identified and addressed as appropriate in accordance with SRP Section 14.3. 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. 7.5-3 Draft Revision 6 – August 2015 3.
