<p>PURPOSE:To deeply understand physical mechanics of an incident by providing a function which quantitatively analyzes an influence which each input gives output when the output of multiinput function which is one of components of a dynamic cause and effect network model is abnormal. CONSTITUTION:Data obtained from a nuclear power plant 1 are transmitted to a process computer system 2 and an input monitor system 3. The system 3 decides whether unit conversion and node abnormality occurs or not, and stores measured value and qualitative value in a common data base 7. The results of a guide treating system 4 and an abnormal development analysis system 5 are also transmitted to the data base 7. When the output of multiinput function is abnormal, a multiinput function analysis system 15 quantatively analyzes a grade of influence which each input gives output by the use of plant measured value data and multiinput function parameters, time series data is shown in a trend graph, and a counterplan is possible even if an event except for the scenarios determined occurs.</p> |
