Radiation Immunity Test of Nuclear Power Instrumentation and Control Equipment
Intended to analyze the radiation immunity of nuclear power plant instrumentation and control equipment in electromagnetic interference environments,ensuring high reliability and stability of the equipment in potential radiation environments.A simplified interference model was established for small current instruments such as thermocouples and pressure sensors,and the maximum induced electromotive force that may be generated in cables was theoretically evaluated.The results indicate that unprotected small signal equipment is susceptible to electromagnetic interference,and the induced current generated may exceed the threshold set in the experiment.Therefore,it is recommended to implement protection strategies(such as installing decoupling clamps,increasing cable inductance,using shielding,grounding cables,etc.)to reduce interference from induced currents and electromotive forces.The research results provide important reference values for the design and operation of instrumentation and control equipment in nuclear power plants,ensuring the reliability of the equipment in complex electromagnetic environments.
