Integrating software reliability concepts into risk and reliability modeling of digital instrumentation and control systems used in nuclear power plants
- U.S. Nuclear Regulatory Commission, Office of Nuclear Regulatory Research, Washington, DC 20555 (United States)
As software-based digital systems are becoming more and more common in all aspects of industrial process control, including the nuclear power industry, it is vital that the current state of the art in quality, reliability, and safety analysis be advanced to support the quantitative review of these systems. Several research groups throughout the world are working on the development and assessment of software-based digital system reliability methods and their applications in the nuclear power, aerospace, transportation, and defense industries. However, these groups are hampered by the fact that software experts and probabilistic safety assessment experts view reliability engineering very differently. This paper discusses the characteristics of a common vocabulary and modeling framework. (authors)
