Object Oriented Analysis and Design (OOAD) has been an efficient software engineering approach to model system as group of interacting objects. This approach is used to model Distributed digital control system (DDCS) of power plant in this paper. Complex system modeled in simple Model driven architecture can provide effective theoretical approach for Failure mode and effect analysis (FMEA). FMEA being...
Leak detection in coolant loops of nuclear reactors is critical for the safety and performance of the reactors. The feasibility of using Raman distributed temperature sensor (RDTS) has been studied on a 30m test loop. Temperature in sodium circuits of fast Breeder Reactor (FBR) exceeds 550°C, gold coated fiber is chosen as sensor fibers. Leak is simulated through an artificial micro fissure integrated...
In Fast Breeder Reactor (FBR), shutdown system is envisaged by Safety and Control Rod Acceleration Movement by using (SCRAM) signals. These SCRAM signals are realized with redundant triplicate sensors, which are made available at different locations of reactor. In this case sensors should be in healthy condition to run the reactor in trouble free manner. To know the health status of sensors a monitoring...
