Yan Xuekun Jia Mingchun Zhang Yan Liu Mingjian Luo Ming (author)Īn automatic single channel analyzer based on single-chip microcomputer The paper presents reliability analysis of microcomputer boards and case study of a CBS system built using these boards. The estimated failure rate values of these standardized microcomputer boards will be useful for reliability assessment of these systems. Reliability analysis of these boards is being carried out using analysis package based on MIL-STD-217Plus methodology. These boards form the basic building blocks of CBS. For forthcoming CBS, Reactor Control Division has designed and developed a new standardized family of microcomputer boards qualified to stringent requirements of nuclear industry. Patil, R.K.Ĭomputer Based Systems (CBS) are employed in Indian nuclear plants for protection, control and monitoring purpose. Reliability analysis of microcomputer boards and computer based systems important to safety of nuclear plants This report desribes the various boards developed and the functions available on each. The use of standard bus and boards provides considerable savings in engineering time, prototyping, testing and evaluation costs, and maintenance support. and are also proposed to be used in additional systems under developement. These boards have been fabricated and tested and used in several systems including Channel Temperature Monitoring systems, Disturbance Recording Systems etc. Standard VME bus based boards have been developed to provide the most used functions. Several operator information systems for nuclear plants has been developed in the Division and these have involved extensive use of microcomputer boards for achieving various functions.
