Oval reactor building arrangement method

The invention provides an elliptical reactor building arrangement method which comprises the following steps: arranging a nuclear auxiliary building at a central elliptical position, arranging an elliptical annular reactor building at the periphery of the nuclear auxiliary building, disconnecting the middle section of the left side of the reactor building, arranging a spent fuel building, and forming a complete elliptical annular shape by the reactor building and the spent fuel building. Main steam and main water supply pipe wells are arranged on the periphery of the reactor building. According to the invention, the arrangement mode in the containment can be optimized, a plurality of NSSS modules can be accommodated in the containment, and feasibility is provided for a high-power nuclear island plant. 本发明提供了一种椭圆形反应堆厂房布置方法，在中心椭圆位置布置核辅助厂房，在核辅助厂房外围布置椭圆环形的反应堆厂房，反应堆厂房的左侧中段断开并布置乏燃料厂房，反应堆厂房与乏燃料厂房组成完整椭圆环形，反应堆厂房的外围布置主蒸汽及主给水管井。本发明能优化安全壳内部的布置方式，实现安全壳内可以容纳多个NSSS模块，为大功率核岛厂房提供可行性。
