INSTRUMENTATION & CONTROL v Electronic instruments are used to monitor reactor parameters and to automatically shut down the reactor if the reactor parameters safety limit is exceeded. v The electronic instruments of the reactor console need to verify to function properly before any reactor operation could be carried out. Functions: v for monitoring and display reactor parameters such as; neutron flux or reactor power, bulk water temperature, rate of power , chart copy of power recording v for protecting the reactor from abnormal circumstances that could result accidents v for controlling the reactor power by withdrawal and positioning the control rods, maintaining and regulating the reactor power ‘set ‘ value 18
