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...
Prototype Fast Breeder Reactor (PFBR) is liquid Sodium cooled, mixed oxide fuelled, fast breeder reactor being built in Kalpakkam, India. This is a first of its kind in India by which we enter into the second stage of the 3-stage nuclear program in commercial scale. Three layered Distributed Digital Control System (DDCS) architecture was decided to be implemented for this reactor. The Graphical User...
Remote Terminal Units (RTUs) are single board, real time remote data acquisition & control systems that are used in Fast Breeder Reactors to acquire analog/digital signals [like voltage, signal inputs from surface thermocouple, leak detector & limit switches], sends digitized data packets over Ethernet to the nearest Local Control Centre (LCC) and generate control outputs in the form of potential...
Even after so many years of research and development in building formal software specification languages, they are not yet popular in the industry for real-world applications. The number of reported success of using formal methods in industrial applications still remains very low. The reasons include: difficulty in learning new and complex mathematical notations, scarcity of experts in the field and...
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...
