Abstract :
Neutron Flux Monitoring System (NFMS) plays an important role in the safety of sodium cooled fast reactors. NFMS measures the reactor power and the reactivity changes in the core. The neutron detectors sense the neutron flux at suitable locations representing the core flux and the signal conditioning electronics processes the signal to get logarithmic power, linear power, period and reactivity parameters. These parameters aid in control of reactor power and initiate safety action on crossing the threshold.
