Abstract
The fault activity in the area surrounding a nuclear power plant is crucial and critical for site selection. This study aims to analyze the fault activity in the surrounding sea areas of the Cang-nan nuclear power plant. The strata information is obtained by both a high-resolution multi-channel seismic survey and a single-channel seismic survey. Based on the processed seismic data, the seismic profiles are interpreted by combining the regional tectonic background and the exploration data from the neighboring nuclear power plant. Seven seismic reflection interfaces are obtained by using the seismic stratigraphy method. According to the active fault criterion, no fault is found in the Quaternary sedimentary layer, indicating that no breakpoint exists. The results show that there is no Quaternary active fault in the concerning area of the Cang-nan nuclear power plant (<25 km) and the site can meet the requirements of the industry standard.
Highlights
Withincreasing population and rapid economic development, traditional hydrocarbon fuels will face the risk of depletion, as they are non- renewable resources
Security is a primary issue for a nuclear power plant, which must be considered in the selection of the plant site
The determination of active faults since the Quaternary near the plant site and its surrounding area is required before the site is chosen (Bengang and Hbnglin, 1993; Zhao et al, 2001; Xiangdong, 2006; Wang et al, 2013; Aurelio et al, 2013)
Summary
Withincreasing population and rapid economic development, traditional hydrocarbon fuels will face the risk of depletion, as they are non- renewable resources. Renewable energy resources, which must be evaluated as the main alternative to hydrocarbon fuels, can have a lower impact on the environment and are receiving increased attention. As a high efficiency source (Shi, 2007; Zhou et al, 2011), could satisfy the needs for increase energy production and has an important role in changing the global situation regarding resource shortages. Unlike the traditional hydrocarbon fuels, a nuclear power plant does not discharge SO2, NOx, dust, or the greenhouse gas-CO2, so it has little influence on the environment and human health in its normal operating state. The determination of active faults since the Quaternary near the plant site and its surrounding area is required before the site is chosen (Bengang and Hbnglin, 1993; Zhao et al, 2001; Xiangdong, 2006; Wang et al, 2013; Aurelio et al, 2013)
