The Gas Turbine Modular Helium Reactor Optimum Design for Instrumentation and Control

Nuclear power plants rely on instrumentation and control (I and C) systems for monitoring, control and protection. While the earlier generations of nuclear plants were built with largely analog instrumentation systems, the industrial base has moved to digital based system. The reason for this transition to digital I and C systems lies in their important advantage over existing analog systems. In essence, the challenge is to prove that the new digital guidelines included in NUREG 0800, Standard Review Plan Chapter 7 and all associated documents provided adequate direction and safety review for an advanced control design for a new nuclear plant in the United States. This paper focuses on how one of the new designs incorporates the latest technology and meets the new NRC requirements. (authors)
