Abstract: The design of Indonesian Experimental Power Reactor (Reaktor Daya Eksperimental/RDE) has been engaged since 2015. The ten-MWth RDE, which is a pebble-bed high-temperature gas-cooled reactor, produces 520℃ steam that can be used for cogeneration application. The design of instrumentation and control system to ensure safe plant operation is outlined. Engineering design methodology is applied. The RDE’s control system, consisting power control, circulator control, feed water control, steam pressure control, pump control, and turbine and generator control, has been developed. In addition, a reactor protection system for RDE has also been proposed. Its schematic protection measures, starting with detection, triggering conditions, anticipated accidents, and protection trip modules, are described. The design of RDE I&C system architecture, having four levels, i.e. process interface, control & protection system, communication network, and man-machine interface, is provided.
