Safety protection subsystem design description
The Plant Protection and Instrumentation System is one of the systems comprising the MHTGR plant. The design of this system has been developed through the Integrated Approach toward safe and economical production of electrical power. The Plant protection and Instrumentation System has three subsystems (Safety Protection, Investment Protection, and Special Nuclear Area Instrumentation). This document defines the functions of the Safety Protection Subsystem, subsystem design requirements derived from the functional analysis, and institutional requirements from the Overall Plant Design Specification. A description of the subsystem design which satisfies the requirements is then presented. Lower-tier requirements at the component level are next defined. This document also includes information on aspects of subsystem construction, operation, and maintenance. The Safety Protection Subsystem monitors and protects plant systems to protect public health and safety. The system monitors selected system process variables, compares the sensed values to preselected levels and, as required, commands and initiates predetermined plant corrective actions. The scope of the system starts with and includes the process sensors to the input of the actuated equipment.
