20080288121 | METHOD FOR DETERMINISTIC SAFETY ANALYSIS IN NON-STATIONARY HIGH RISK SYSTEM, CONTROL METHOD AND CONTROL SYSTEM USING THEREOF - A method and systems of safety analysis of engineering processes for safety analysis of nuclear power stations are disclosed. A distribution of risk factors is analysed on different stages of the engineering process, and safety intervals are determined where safety conditions remain invariable. The method further includes analysis of failure transitions from one safety interval into another by means of cause-effect analysis. Based on the results of this analysis, deterministic safety models are created for possible scenarios of transition of failures from one safety interval into another. The method and systems provide quantitative safety analysis and evaluation for engineering processes in variable safety conditions and enable creating valid safety requirements to perform optimisation of an engineering processes control system. | 11-20-2008 |
