IFMIF-DONES Central instrumentation and control systems: General overview

Abstract Purpose of this work is to describe the Central Instrumentation and Control Systems for the International Fusion Materials Irradiation Facility-DEMO Oriented NEutron Source. A functional definition of the main systems is given, together with a general overview of the current status of the Central Instrumentation and Control Systems and the differences with respect to the corresponding system developed during the previous phases. The overall architecture of the Central Instrumentation and Control Systems (definitions, functions and requirements), the identification of subsystems and equipment, the control system design guidelines, and the Control Room requirements, are here described. Moreover, the Local Instrumentation and Control Subsystems is defined together with its relationship with the Central Instrumentation and Control Systems.
