Nuclear power plant’s safety against seismic events is evaluated as risk values by probabilistic seismic safety assessment. The risk values vary by the seismic failure correlation between the structures, systems, and components (SSCs). However, most probabilistic seismic safety assessments idealized the seismic failure correlation between the SSCs as ...

Development of a Seismic Probabilistic Safety Assessment Quantification Tool
Journal of Nuclear Engineering and Radiation Science, 2018Shanghai Nuclear Engineering Research and Design Institute (SNERDI) has been studying seismic risk analysis for nuclear power plant for a long time, and completed seismic margin analysis for several plants. After Fukushima accident, seismic risk has drawn an increasing attention worldwide, and the regulatory body in China has also required the ...

Seismic probabilistic risk assessment for seismically isolated safety-related nuclear facilities
Nuclear Engineering and Design, 2017Abstract In the United States, seismic probabilistic risk assessment is performed on nuclear power plant (NPP) designs to calculate mean annual frequencies of unacceptable performance, including core damage and large early release (of radiation). Seismic (base) isolation is a viable strategy to protect NPPs from extreme earthquake shaking but it has ...

Application of Bayesian statistics to seismic probabilistic safety assessment for research reactor
Nuclear Engineering and Design, 2018Abstract Nuclear facilities are susceptible to the damage due to earthquake hazards. The recent strong earthquake events show the need to explore scenarios in which the expected seismic hazard exceeds a design basis earthquake. In this regard, the seismic probabilistic safety assessment (SPSA) methodology has been developed and utilized to access the

A semi-probabilistic safety-checking format for seismic assessment of existing RC buildings
2011The present work focuses on probability-based safety-checking formats suitable for implementation in codes for the purpose of the assessment of existing buildings. As an alternative to the current ap- proach in the European code based on applying the conf idence factors, a semi-probabilistic approach is pro- posed based on applying a bias factor and a ...

Dynamical Seismic Probabilistic Safety Assessment for Earthquake
2012In the nuclear power plants (NPPs), the earthquake could make a critical result because of its catastrophe risk. It is important to maintain the stability of the system without the radiation material leak from the reactor. The system dynamics (SD) is used in analysis by the random sampling quantification of the earthquake happening due to unexpected ...

Evaluation of response factors for seismic probabilistic safety assessment of nuclear power plants
Nuclear Engineering and Design, 1994Abstract This paper presents a method for evaluating “response factors” of components in nuclear power plants for use in a seismic probabilistic safety assessment (PSA). The response factor here is a measure of conservatism included in response calculations in seismic design analysis of components and is defined as a ratio of conservative design ...

Methodology and results of the seismic probabilistic safety assessment of Krško Nuclear Power Plant
Nuclear Engineering and Design, 1998Abstract A seismic IPEEE (Individual Plant Examination for External Events) was performed for the Krsko plant. The methodology adopted is the seismic PSA (probabilistic safety assessment). The Krsko NPP is located on a medium to high seismicity site. The PSA study described here includes all the steps in the PSA sequence, i.e.

Probabilistic seismic safety assessment of bridges with random pier scouring
Proceedings of the Institution of Civil Engineers - Structures and BuildingsFoundation scour has been a reason for several cases of river-bridge earthquake-induced failure during recent decades. However, practising engineers often do not consider its direct effect on the seismic design procedure of such structures. The cavity around a bridge foundation is a random phenomenon depending on several uncertain parameters.
