Nuclear meltdown is a severe nuclear reactor accident that occurs due to core overheating. A core melts when the heat generated by a nuclear reactor exceeds the heat removed by the cooling systems to the point where at least one nuclear fuel element exceeds its melting point. This may be caused by loss of coolant, loss of coolant pressure or low coolant flow rate. Hence monitoring of coolant flow becomes most important in order to protect the core from meltdown. In Fast Breeder Nuclear Reactors, sodium acts as the main coolant. So continuous monitoring of sodium flow is required with great accuracy and with a faster response time for taking the remedial actions quickly if the coolant flow is less than the required flow. The paper describes the design of continuous monitoring of sodium flow rate using a mixed signal array microcontroller (Programmable System on Chip - PSoC) for receiving the real-time signal from the sensor and for processing the sodium flow rate. It focuses on the hardware design and programming of PSoC microcontroller for this specific application of sodium flow monitoring with reduced response time.
