Modular building method of nuclear power plant stainless steel cladding surface

Abstract

The invention discloses a modular building method of a nuclear power plant stainless steel cladding surface. The method comprises the following steps of (1) designing and prefabricating a stainless steel cladding surface module; (2) transporting the stainless steel cladding surface module to a construction mounting field; (3) constructing a civil engineering structure at a positioning place of the stainless steel cladding surface module, wherein the step (1) and the step (2) are parallel steps and are performed at the same time; (4) placing the stainless steel cladding surface module to the civil engineering structure; (5) casting concrete to the surrounding of the stainless steel cladding surface module, so that the stainless steel cladding surface module is mounted. Compared with the prior art, the method has the advantages that due to the fact that the stainless steel cladding surface is made into the module structure, the step of constructing the civil engineering structure and prefabricating the stainless steel cladding surface module can be constructed at the same time, the shortening of the construction period of the whole cladding surface field is facilitated, and the construction efficiency and the welding quality of the stainless steel cladding surface can also be improved.

Description

technical field [0001] The invention belongs to the field of design and construction of nuclear power plants. More specifically, the invention relates to a modular construction method for stainless steel cladding of nuclear power plants. Background technique [0002] In nuclear power plants, nuclear fuel and waste transportation and storage sites, such as refueling pools, spent fuel pools, pits and trenches, etc., all need to be covered with stainless steel cladding to contain radioactive products to prevent the leakage of radioactive materials to the environment . [0003] see figure 1 , the current stainless steel cladding is constructed by the method of on-site cladding and lining. The process is to carry out civil construction first. After the construction of the entire room or other structures is completed, or after the construction of several floors, the construction of cladding and lining can be carried out. The specific steps are as follows: : 1) Carry out a concre...
