Risk Evaluation Method for Faults Displacement by Engineering Approach (1)The Outline on the Report of the Committee of AESJ and Application Concept of Margin Analysis Utilizing Accident Sequences

The structural integrity of equipment and piping systems to a fault displacement depends on the damage state of a reactor building. When there is no damage in a reactor building, the supporting function of equipment and piping systems is maintained. In this case, FEM analysis can estimate the allowable state of the entire system of the important safety equipment. In this part, an example of the analysis evaluation for the equipment and piping systems, which are important for safety, in the case of loading a...

Risk Evaluation Method for Faults Displacement by Engineering Approach (4)The Analysis Evaluation of Equipment and Piping System

Studies have been carried out about fault displacements under the facilities as external hazard、 and risk evaluation method for influence on facilities by fault displacements using engineering approach、 _accident management” for domestic nuclear facilities. In this paper it shows the scenario of accident results in fault displacements directly under the nuclear power station causes loss of safety of the plant、 and shows risk evaluation method measures for the image of quantitative effect of risk reducti...

Risk Evaluation Method for Fault Displacements by Engineering Approach (5)Measures for Risk Reduction by Accident Management

The influence of the fault displacement on the facility should be evaluated not only by the activity of the fault but also by obtaining risk information by considering scenarios including such as the degree and the frequency of the hazard, which should be an appropriate approach for nuclear safety. In this paper, the basic thinking of nuclear safety for fault displacement utilizing the concept of defense-in-depth and risk evaluation approach is proposed. ...

Risk Evaluation Method for Faults by Engineering Approach (1) Nuclear safety for accident scenario and measures for fault movement

The influence of the fault displacement on the facility should be evaluated not only by the activity of the fault but also by obtaining risk information by considering scenarios including such as the degree and the frequency of the hazard, which should be an appropriate approach for nuclear safety. An applicable concept of margin analysis utilizing accident sequences for evaluating the influence of the fault displacement is proposed. By use of this analysis, we can evaluate of the safety functions and mar...
