Abstract
Cyber is a buzzword these days—the destabilizing, invisible, insidious battleground that is shaking everything from financial institutions, hospitals, and airports to average individuals in an ever increasingly Internet-dependent world. The cybersecurity challenges facing nuclear power plant industrial control systems are much the same as for other industries where maintaining high availability of services is imperative. In this chapter, the authors discuss the development of cyber-resilient industrial control system technologies for nuclear power plants with a focus on operator support systems. These concepts culminate in the design and demonstration of the Fault Understanding Navigation and Control Interface (FUNCI) visualization system for cyber-resilient operation. Finally, the authors present the results of a study involving nuclear power plant operators.
