Instrumentation and Control systems (I&C) play a significant role in nuclear power plants (NPP) and other safety critical systems (SCS). We have conducted a rigorous study and discussions with experienced practitioners worldwide the strategy for the development of I&C systems to investigate the several aspects related to their dependability. We discussed with experienced practitioners that work on nuclear domain with the intention of knowing their approach, they use day-to-day for the development of such systems. The aim of this research is to obtain to provide guidance to those building I&C systems of NPP and have implications on state engineering licensure boards, in the determination of legal liability, and in risk assessment for policymakers, corporate governors, and insurance executives.

仪表和控制系统 (I&C) 在核电厂 (NPP) 和其他安全关键系统 (SCS) 中发挥着重要作用。我们与全球经验丰富的从业者就 I&C 系统的开发策略进行了严格的研究和讨论，以调查与其可靠性相关的几个方面。我们与在核领域工作的经验丰富的从业者进行了讨论，目的是了解他们的方法，他们每天都在使用这种系统开发。本研究的目的是为建立核电厂 I&C 系统的人员提供指导，并对国家工程许可委员会、法律责任的确定以及政策制定者、公司管理者和保险高管的风险评估提供指导。
