Embodiment Construction

[0017] The technical solution of the present invention will be further elaborated below in conjunction with the accompanying drawings.

[0018] The core support structure of a pool-type sodium-cooled fast reactor is as follows: figure 1 As shown, the equipment is composed of a large grid header 14 , a small grid header 11 , and a core shroud 10 . The external dimensions of the core support structure and the number of small grid headers 11 can be determined according to the core layout of different stack types.

[0019] The outer diameter of the large grid header 14 is Φ2035, and the height is 800mm. The upper flange 4 is opened and the installation sleeve for the small grid header 11 is installed. 202 small grid headers can be installed, and the upper and lower flanges 4, 1, there are 37 sleeves 13 that supply sodium to the small grid header 11 in the middle part, and vertical holes 5 are set on the sleeves 13, and sodium enters the small grid header from the large grid heade...

Abstract

The invention discloses a reactor core supporting structure of a pool-typed sodium-cooled fast reactor. The reactor core supporting structure of the invention comprises a large grid-plate header, a small grid-plate header and a reactor core support barrel, which results in that the number of opening of the large grid-plate header and the structural complexity of the large grid-plate header are both greatly reduced and the entire rigidity of the reactor core supporting structure is also improved. In addition, the small grid-plate header which is split can more easily achieve the distribution of the flow required by different reactor core components.

Description

technical field [0001] The invention belongs to the technical field of reactor core structure, and in particular relates to a core support structure of a pool type sodium-cooled fast reactor. Background technique [0002] In the pool-type sodium-cooled fast reactor, the core support structure is an essential part. It is the direct support and positioning reference of the reactor core assembly, and is also the distribution center of the core coolant flow. The core of various reactor types Support structures vary. For example, in the U.S. Patent "Diagrid for supporting a nuclear reactorcore, United States Patent 3937653, Feb.10, 1976", a core support structure called a core grid plate is provided, which is a box-like structure composed of The upper and lower flanges are composed of a cylinder. The upper flange is a circular grid plate, and the lower flange is a dome structure. A lot of pipe sockets with holes are welded between the upper and lower flanges corresponding to eac...
