In order to cope with electromagnetic interference that impacts the instrument and control equipment in nuclear power plants and improve the operation reliability of the instrument and control system,this paper takes a 300000 kW nu-clear power project as an example,and discusses the technical scheme in the design of electromagnetic-interference-toler-ant DCS instrument and control platform in the design process of the ventilation control room system.It clarifies the en-tailed technical means including space isolation,shielding,grounding,and electromagnetic interference tolerance manage-ment,and puts forward corresponding suggestions.
