Abstract

The modularized building method for nuclear island of nuclear power plant includes: modularized designing the upstream engineering of a nuclear island of nuclear power plant to divide and/or combine multiple units in the nuclear island into connection units among multiple modules, connection units between modules and connection units between module and exterior; prefabricating module by factory producing mode; building workshop by roof-opening construction mode; mounting the prefabricated module onto preset design position of the workshop. Advantage: raised prefabrication rate and constriction quality, increased engineering speed and low building cost.

Description

technical field [0001] The invention relates to the field of nuclear power plant construction, in particular to the construction of mega-kilowatt and above large nuclear power plants. Background technique [0002] At present, in the construction of nuclear island projects of nuclear power plants that have been put into operation or are under construction in China, the traditional construction, civil engineering and installation construction organization mode is generally adopted, with the component or equipment unit as the smallest unit, and the construction is carried out according to the preset construction sequence. . It has the disadvantages of long construction period, many high-altitude operations, and complicated engineering quality control. [0003] In the prior art, the following technical means have been adopted to try to overcome these shortcomings. [0004] 1) Factory manufacturing technology [0005] The introduction of factory manufacturing in the field of c...
