The digitized instrument control system ( I&C ) platform of nuclear power plant ( NPP ) is analyzed and researched from the perspective of communication. Combining with the commonly used international standards, such as IEEE, etc. , with the digitized I&C platform applied in NPP of APWR project as research object, the overall communication architecture and communication technologies applied for such platform are introduced and analyzed emphatically. In addition, based on relevant regulations, standards, and requirement description of the task, the communication framework of I&C platform of APWR is revised and improved in further. The revised communication framework improves the driving reliability and reduces the response time of the system; furthermore, the risk caused by multiple layer communication is reduced, while the safety performance is improved.
