Abstract: Indonesia is currently developing a design nuclear Pebble Bed Modular Reactor (PBMR) with the reactor name is RDE. This type of reactor requires a system to supply fuel into the reactor core. The system is called the Fuel Handling System (FHS). The selected RDE-FHS is a type of online refuelling system, in which there is no need to turn off the reactor during its refueling time. To ensure the continuity of the process, an Instrumentation and Control System (I&C) is needed so that the parameters on the FHS can be monitored and controlled. An architecture of the FHS-I&C is required in the implementation, so that the connection between sensors, transducers, transmitters and valves can be clearly seen. The main instruments in the FHS include burn up measurement and fuel counting measurement. Burning measurement is needed to determine the fuel value, while fuel counting measurement is needed to calculate the amount of fuel entering and leaving the reactor core. FHS interconnection with other systems in RDE uses communication networks with the Hart protocol and SCADA system.
