基于NASPIC平台的数字化核安全级DCS主辅数据分流研究

Research on Digital Nuclear Security Level DCS Main and Auxiliary Data Diversion Based on NASPIC Platform

核电站数字化安全级DCS系统被称为核电站的“神经中枢”,对安全、可靠性要求极高。在该系统中,参与执行停堆保护和专设安全设施驱动功能的数据是重要信息,与反应堆安全直接相关需要优先处理。本文通过深入研究安全级DCS的架构,提出主辅数据分流思想,优先保证与安全功能直接相关的主要数据安全可靠处理和传输,提高数字化安全级DCS的安全性、可靠性,进而有利于保证核电站的安全可靠运行。

The digital safety level DCS system of nuclear power plants is called the nerve center of nuclear power plants and has extremely high requirements for safety and reliability.Data invoved in the implementation of shutdown protection and dedicated safety facility drive function is important information and information directly related to reactor safety need to be prioritized in this system.Through in-depth study of the architecture of the security level DCS,this paper proposes the idea of main and auxiliary data diversion.And this ensure that primary data directly to security functions is processed and transmittedpreferentially.This idea improves the security and reliability of the digital security level DCS,and helps to ensure the safe and reliable operation of nuclear power plant.
