High dependability on Instrumentation and control (I & C) systems calls utmost importance for smooth functioning as well as the safety of Nuclear power plants. I&C systems are employed for monitoring of the parameters, control of these parameters and protection of the plant and persons. The Embedded systems play major role in design and development of I&C systems. While designing I&C...
Leak detection in the coolant loops of Fast Breeder Reactor (FBR) is critical for the safety of the reactors. This paper discusses the feasibility of using Raman Distributed Temperature Sensor (RDTS) for leak detection in double walled pipelines of primary sodium circuits in FBR. The leak detection is based on the resultant change in temperature due to leak. Since handling sodium is difficult, as...
At Kalpakkam, India, a programme on development of Raman Distributed Temperature sensor (RDTS) for Fast Breeder Reactors (FBR) application is undertaken. Leak detection in sodium circuits of FBR is critical for the safety and performance of the reactors. It is demonstrated that RDTS can be usefully employed in monitoring sodium circuits and in tracking the percolating sodium in case of any leak. Aluminum...
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...
