Engineering simulator for advanced heavy water reactor

An engineering simulator for the Advanced Heavy Water Reactor (AHWR) has been developed, installed and commissioned at the AHWR Integrated Test Station (ITS), RCnD, BARC, Trombay. This is a computer-based real time simulator employing mathematical models of coupled core neutronics-thermal hydraulics and all major plant systems of AHWR. The developed system is capable of simulating the dynamic response of the plant under both normal and off-normal operating conditions, and is being used in verification and validation of plant control algorithms and safety interlocks, hardware in the loop testing of prototype Control and Instrumentation (C and I) systems of AHWR, design of control room interfaces etc. Important features of this engineering simulator and results of some of the transient simulation studies.
