帽子山候选厂址区域范围绝大部分在扬子准地台范围内。区内深大断裂多分布在二级构造单元的分界线上。大别山、怀玉山、九岭等３个隆起区、鄱阳湖、九江─芜湖等２个沉降区和夹于它们之间的庐江─广济、庐山─梅岭、万年─黄石、北淮阳、铜陵─宁国等构造变形带组成了候选厂址区域范围新构造期的基本构造格局。通过布格异常梯度值、重力异常与高程的相关系数、地壳应变能量、地震震级、地震基本烈度、叠加断裂角等地壳稳定性分级指标的综合分析与对比，候选厂址区域范围可划分为九江─安庆、怀玉山、鄱阳湖、九岭稳定亚区及北淮阳─铜陵、大别山基本稳定亚区。帽子山候选厂址位于九江─安庆稳定亚区内．具备核电厂建设的区域地壳稳定性条件。
The majority of the hat mountain candidate site area is within the scope of the Yangtze Platform. Deep faults in the area are mostly distributed on the dividing line of secondary tectonic units. Dabieshan, Huaiyushan, Jiuling and other three uplifts, Poyang Lake, Jiujiang-Wuhu and other two subsidence and sandwiched between them Lu Jiang - Guangji, Lushan ─ Meiling, Wannian - Yellowstone, North Huaiyang, Tongling ─ Ningguo tectonic deformation zone composition of the candidate site area range of the new tectonic period of the basic tectonic framework. Based on the comprehensive analysis and comparison of the grading index of crustal stability such as Bouguer’s abnormal gradient, correlation coefficient of gravity anomaly and elevation, crustal strain energy, earthquake magnitude, basic earthquake intensity and superimposed fracture angle, the candidate site area can be divided into Jiujiang- Anqing, Huaiyu Mountain, Poyang Lake, Jiuling stable sub-region and the northern Huaiyang ─ Tongling, Dabie Mountain basic stable sub-region. Hat Hill candidate site is located in Jiujiang - Anqing stable sub-region. Regional crustal stability conditions for nuclear power plant construction.
