Problems solved by technology

[0003] However, for some occasions where the site is limited (for example, a compact arrangement of equipment reactors), the distance between the main equipment of the reactor primary circuit is small, there are many interfaces between the equipment, the installation accuracy is high, the installation content is complicated, and the site installation and construction conditions are limited.
Therefore, the traditional method of installing the main equipment of the primary circuit of a land-based nuclear power plant reactor is not applicable

Abstract

The invention discloses a reactor primary loop main equipment mounting method which comprises the following steps: S1) assembling a reactor pressure vessel, reactor internals, an inner sleeve, a steam generator and a main pump shell into a vessel module in advance, and assembling a reactor pressure vessel top cover, a control rod driving mechanism and a reactor top structure into a reactor top module in advance; s2) mounting a main equipment bracket and a voltage stabilizer bracket; (S3) the container module is hoisted to the main equipment support, the position of the container module is adjusted, and the container module is installed on the main equipment support; and S4) mounting a voltage stabilizer on a voltage stabilizer bracket, connecting a main pump motor and a hydraulic component with a main pump shell, and mounting the reactor top module on the container module. Compared with the prior art, the installation method of the primary loop main equipment of the reactor has the advantages that the equipment is pre-assembled into the container module and the reactor top module in the equipment assembly factory, and then the container module and the reactor top module are transported to the installation site for installation, so that the installation precision and efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of key equipment installation of nuclear power plants, and more specifically, the invention relates to a method for installing main equipment of a reactor primary circuit. Background technique [0002] At present, the main equipment of the primary circuit of traditional land-based nuclear power plant reactors mostly adopts a loop design. During installation, individual equipment is transported to the final assembly plant for installation separately, and the installed equipment is connected to the main pipeline by welding on site. [0003] However, for some occasions where the site is limited (for example, a compact arrangement of equipment reactors), the distance between the main equipment of the reactor primary circuit is small, there are many interfaces between the equipment, the installation accuracy is high, the installation content is complicated, and the site installation and construction conditions are...
