Reliability information system for conventional and nuclear power plants

Subsystems of a reliability information system with feedback are given. The said system was introduced for steam power production units. The collection of primary reliability information is made through the so-called monthly reliability reports which are filled in the department of operation analyses. Primary reliability data are stored on the disk memories of the ASVT computer. The system was also used in the establishment and implementation of the reliability information system for nuclear power plants with WWER 440 reactors. The existing classification of manifestations, causes and mechanisms of failures was analysed, mainly with regard to the effect of the human factor. An introdOctory study is now being compiled relating to the reliability information system for WWER 1000 nuclear power plants. The possibility has appeared of speedily designing and implementing a reliability information system for district heating systems. (E.S.)
