REVIEW RESPONSIBILITIES Primary - Organization responsible for the review of instrumentation and controls Secondary - None I. AREAS OF REVIEW This review of the communications systems is limited to that portion of the system used in intraplant and plant-to-offsite communications during normal operation, transients, fire, accidents, off-normal phenomena, and security-related events. Examples of normal operation intraplant communication are during in-service testing, inspection, and maintenance. An example of normal operation plant-to-offsite communication is between plant operators and offsite electric power grid transmission organization staff to be informed of the nuclear power plant offsite power status. Examples of normal operation plant-to-offsite communication are between plant operators and the NRC Incident Response Center and local authorities when the plant is operating during natural phenomena such as a tornado, hurricane, flood, tsunami, lightning strike, and earthquake. Systems within the scope of this SRP section include voice communications between personnel and organizations. SRP Sections 7.9 and 13.3 address the review of systems for communicating data between portions of the instrumentation systems and between facilities. The specific areas of review are as follows: 1. System Capabilities. The communications system is reviewed with respect to the capability of the system and related plant design features to provide effective intraplant communications and effective plant-to-offsite communications during normal plant operations and during transient, fire, and accident conditions, including loss of offsite power. 9.5.2-2 Revision 3 - 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,
