地下核电厂混凝土施工及大型设备安装技术研究

由于地下洞室内空间有限,而大型核岛设备尺寸较大,在受限的地下空间进行混凝土施工和大型设备安装,是地下核电厂建设可行性研究必须要解决的关键问题。针对地下核电厂混凝土施工及大型设备安装的特点,开展了地下核电厂房洞室混凝土衬砌、反应堆厂房安全壳混凝土施工和大型核岛设备安装的相关技术研究,首次提出了适合地下核电厂混凝土施工和大型设备安装的技术方案,并对相关技术方案实施的可行性进行了论证,为地下核电厂后续的研究和工程实践提供了理论依据。

Research on technology of concrete construction and large equipment installation for underground nuclear power plants

Due to large size of nuclear island equipment and limited interior space of underground cave, so the concrete con-struction and large equipment installation in the limited space is the key problem to be solved in the feasibility study of under-ground nuclear power plants construction. In view of the features of concrete construction and large equipment installation for un-derground nuclear power plants, the research on technology of concrete construction of underground cavern lining and nuclear re-actor containment as well as the installation of large-scale nuclear island equipment were carried out. And the technical solu-tions of concrete construction and large equipment installation were firstly proposed;the feasibility of relevant technical solutions implementation was also demonstrated, all of which can provide technical support for subsequent research and engineering prac-tice of underground nuclear power plants.
