专利汇可以提供Plant status display after earthquake专利检索,专利查询,专利分析的服务。并且PURPOSE: To display a proper plant information and a measure to be taken by an operator immediately after an earthquake by evaluating the probability of damage generation against the judged magnitude of the earthquake vibration and indicating it based on the probability evaluation.
CONSTITUTION: In case of occurrence of an earthquake, the maximum acceleration is measured with an earthquake measurement system A arranged at the basement of reactor building. On the other hand, an earthquake response analysis values (maximum acceleration) at the basement of the reactor building against the S1 (maximum) and S2 (limit) earthquakes are stored in advance in a design information memory B and they are compared to judge and indicate the magnitude of the earthquake vibration D. At the same time, maximum response accelerations at the set floor level of each component are evaluated with a floor response level evaluation device C. Then, the probabilities of component damage are evaluated with an earthquake fragility data memory E for components and systems and they are indicated in the central control room in the order of higher probability. Also, with a PSA analyzer F, the effect on plant safety in the case of occurrence of abnormality in the components and systems is evaluated and displayed.
