Aging and obsolescence of control systems have emerged as a more and more serious problem in multiple industries, including Nuclear Power Plants (NPP). However, both the utilities and regulatory agencies maintain healthy skepticism on any changes of existing engineering systems, if there is a slight uncertainty that the new technology might endanger public safety. Meanwhile, technology advancement in the control field has enabled the emergence of modern control systems, such as Networked Control Systems (NCS). These systems are advantageous in many aspects, such as more flexibility and less maintenance. However, reliability and safety issues have to be adequately addressed before they can be adopted to retrofit existing systems. New design of control systems are also needed to support next generation NPP and other industries.

控制系统的老化和过时已经成为包括核电站（NPP）在内的多个行业中越来越严重的问题。然而，如果新技术可能危及公共安全存在轻微的不确定性，公用事业和监管机构都对现有工程系统的任何变化持健康的怀疑态度。与此同时，控制领域的技术进步使得现代控制系统，如网络控制系统（NCS）的出现成为可能。这些系统在许多方面是有利的，例如更大的灵活性和更少的维护。然而，在采用这些系统改造现有系统之前，必须充分解决可靠性和安全性问题。还需要新的控制系统设计来支持下一代NPP和其他行业。
