Problems solved by technology

[0002] The heat removal system of the existing pool reactor pool mainly utilizes the non-phase-change heat transfer of the working fluid in the system. This cooling cycle has the problem of low heat transfer efficiency due to the small temperature difference between the pool heat source and the external air. In addition, the existing The heat removal system needs to rely on active equipment. In the event of an accident, the waste heat of the core cannot be exported, and there are hidden dangers of unsafety in human intervention.

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] Such as Figures 1 to 2 As shown, the cooling system 100 according to the embodiment of the present invention includes an air induction device 130 and at least one set of cooling circuits 140, wherein the air induction device 130 is arranged at an upper position outside the pool reactor pool 110 for increasing air flow rate. The wind-inducing device can be a wind-inducing tower. Using the cooling system 100 according to the embodiment of the present invention, for example, by arranging the air induction device 130 at an upper position outside the pool reactor pool 110, the air can be guided to move in an organized manner and the flow speed of the air can be accelerated.

[0019] figure 1 , 2 The cooling system 100 of the embodiment of the present invention is shown to include two sets of cooling circuits 140, but in some embodiments ...

Abstract

The embodiment of the invention provides a cooling system. The cooling system comprises an air inducing device and at least one group of cooling loops, wherein the air inducing device is arranged at the upper position outside a pool type reactor water pool and is used for increasing the flow rate of air; and the cooling loop comprises a first heat exchanger, a second heat exchanger, a first pipeline, a second pipeline and a valve. The cooling loop in the cooling system provided by the invention adopts a separated heat pipe principle, passive export of decay heat in the pool type reactor pool can be realized without depending on any active equipment and human intervention, and the cooling system has high safety.

Description

technical field [0001] The invention relates to a cooling system, especially a cooling system for discharging waste heat of a pool reactor. Background technique [0002] The heat removal system of the existing pool reactor pool mainly utilizes the non-phase-change heat transfer of the working fluid in the system. This kind of cooling cycle has the problem of low temperature difference between the pool heat source and the external air, which makes the heat transfer efficiency low. In addition, the existing The heat removal system needs to rely on active equipment. In the event of an accident, the waste heat of the core cannot be exported, and there are hidden dangers of unsafety in human intervention. Contents of the invention [0003] The purpose of embodiments of the present invention is to provide a cooling system whereby, for example, the residual heat of a pool reactor can be efficiently and safely removed. [0004] According to an embodiment of the present invention,...
