Flow equalization piping assemblies for pooled nuclear reactors

Abstract

The invention discloses a flow distribution pipe assembly for a pool type nuclear reactor. The flow distribution pipe assembly includes: an inflow pipe; a flow distribution unit connected to the inflow pipe, and the flow distribution unit is arranged in a There is a reactor pool of the reactor body; a plurality of flow distribution pipes connected to the fluid distribution unit, the plurality of flow distribution pipes are arranged to extend in multiple directions, so as to guide the fluid to multiple channels along the circumference of the reactor pool a position; and an outflow pipe, configured to lead out the fluid after heat exchange with the reactor body to the outside of the reactor pool.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of nuclear engineering, in particular to a flow equalizing pipe assembly for a pool type nuclear reactor. Background technique [0002] The pool-type nuclear reactor is an atmospheric nuclear reactor that utilizes the static pressure of the deep water layer. The reactor body is placed in the reactor pool, and the fluid in the reactor pool exchanges heat with the reactor body. The fluid after heat exchange is exported to the reactor through the outflow pipe. The primary circuit system outside the pool transfers the heat generated by the reactor body to the primary circuit system, which can ensure the inherent safety of the reactor body and effectively utilize the heat. [0003] In the prior art, fluid generally enters the reactor pool from an inflow pipe installed on the side wall of the reactor pool, and the inflow pipe is set as a single straight pipe. Since the temperature of the...

Problems solved by technology

Since the temperature of the fluid in the inflow pipe is lower than that in the reactor pool, the temperature of the fluid in the reactor pool near the inflow pipe is lower, while the temperature of the fluid on the side farther away from the inflow pipe is higher, so that in different directions There is a temperature difference between the fluid that exchanges heat with the reactor body, which further leads to uneven temperature distribution inside the reactor body, which will have a certain impact on the uniform heat transfer of the reactor body, and may also affect the working performance and safety of the reactor body
