Seismic fragility analysis has been widely used to evaluate seismic capacities of structures, systems, and components (SSCs) in nuclear power plants. In the seismic fragility analysis, a single ground motion parameter (GMP),such as peak ground acceleration (PGA), is chosen to characterize the Review Level Earthquake (RLE) and represent the Author: Zhen Cai.

Seismic Design Criteria for Structures, Systems, and Components in Nuclear Facilities provides stringent design criteria for nuclear facilities. Because of the potential risk associated with nuclear hazards, nuclear facilities should have a lower probability than conventional facilities of sustaining structural damage caused by earthquake.

One major aspect of conservatism in the design is ignoring the effect of soil-structure interaction (SSI), which results in conservative estimates of seismic demands for plant equipment. In this paper, a typical reactor building (RB) is chosen for a case study to investigate the potential benefit of accounting for SSI by: 1.

For seismic safety evaluation method of nuclear power plant, nuclear power plant seismic margin analysis (SMA) and nuclear power plant seismic probability safety assessment (SPSA) are the most widely used methods.

SMA is a method base on deterministic theory. Seismic capacity is valued by high confidence and low failure probability (HCLPF).Author: Zhao Wang, Jianfeng Yang, Weijin Wang, Bingchen Feng, Xiaoming Zhang.

fragility analysis of a nuclear power plant and its components was conducted by Kennedy et al. [2]. This method was modified later to a more systematic approach by Kennedy and Ravindra. Appendix A to Part —Seismic and Geologic Siting Criteria for Nuclear Power Plants. Purpose.

General Design Criterion 2 of Appendix A to part 50 of this chapter requires that nuclear power plant structures, systems, and components important to safety be designed to withstand the effects of natural phenomena such as earthquakes, tornadoes, hurricanes, floods, tsunami, and seiches.

This paper presents the procedures and results of intensity- and time-based seismic risk assessments of a sample nuclear power plant (NPP) to demonstrate the risk-assessment methodology proposed in its companion paper.

The intensity-based assessments include three sets of sensitivity studies to identify the impact of the following factors on the seismic vulnerability of the sample NPP, namely.

The response of nuclear power plants (NPPs) to seismic events is affected by soil-structure interactions (SSI). In the present paper, a finite element (FE) model with transmitting boundaries is used to analyse the SSI effect on the response of NPP buildings subjected to vertically incident seismic excitation.

Analysis parameters that affect the accuracy of the calculations, including the Cited by: 1. However, seismic walk-downs at some of these plants indicate that very little damage occurred to safety class systems and components due to the seismic motion.

Therefore, it is necessary to gather the applicable data to quantify the margins in current seismic analysis techniques (linear analysis) at nuclear power plants. Need: High. Seismic safety of nuclear power plants became an eminent importance after the Great Tohoku earthquake on 11th of March, and subsequent disaster of the Fukushima Dai-ichi nuclear power plant.

Seismic Risk Management Solution for Nuclear Power Plants By Justin Coleman and Piyush Sabharwall. Abstract. Nuclear power plants should safely operate during normal operations and maintain core-cooling capabilities during off-normal events, including external hazards (such as flooding and earthquakes).File Size: KB.

The re-evaluation and upgrading of the seismic safety of the operating nuclear power plants were motivated mainly by the changing understanding of the seismic hazard at plant sites and/or recognition of inadequacy of design and/or qualification of certain safety related systems, structures and components relative to the seismic hazard or state Cited by: 6.

The development of protective measures to guard against the spread of radioactive debris following reactor disasters has been given extensive and careful engineering attention over the past several years.

Much of this attention has been devoted to eliminating or minimizing the effects of malfunctions of internal components. But reactors can also suffer externally caused disasters – for.
