Hot end block, thermoelectric power generation system, liquid stack and its operation method and application

Abstract

The invention discloses a hot end seat, a thermoelectric power generation system, a liquid stack and an operation method and application thereof. The hot end seat is used to cooperate with the condensing end of the core heat pipe in the liquid reactor; The 1st to the Nth area; the hot end block includes the first layer to the Nth layer of hot end sleeves from bottom to top, and the outer diameter of the hot end sleeves becomes smaller layer by layer from bottom to top; the hot end sleeve of the hot end block and the stack The area corresponding to the condensing end of the core heat pipe; the hot end sleeve has a center body and an outer edge body surrounding the center body; the center body is used to pass through the core heat pipe in the area corresponding to other layers above the layer; the outer edge body is provided with a core The heat pipe channel, the core heat pipe channel is used to accommodate the core heat pipe condensation end of the core heat pipe in the region corresponding to the layer. The hot end seat of the present invention can smoothly take out the heat of the core heat pipe, avoid local hot spots, and improve heat utilization rate and temperature difference power generation efficiency.

Description

technical field [0001] The invention relates to a hot end seat, a thermoelectric power generation system, a liquid stack and an operation method and application thereof. Background technique [0002] In the reactor system using heat pipes for core cooling, when one or more heat pipes in the core fail, the nuclear reaction heat of the failed heat pipe fuel assembly is exported to the core through the heat pipe in the center of the adjacent fuel assembly, thereby effectively avoiding a single point of heat transfer in the core Failure, therefore, has the advantage of being inherently redundant. Furthermore, the reactor system using heat pipes for core cooling has the advantages of easy start-up and no need for other auxiliary systems, so it has attracted special attention. In addition, since the heat pipe is directly inserted into the core and connected to the subsequent thermoelectric conversion system, the heat exchange between the core coolant and the external circuit is o...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to overcome the heat pipe molten salt reactor temperature difference power generation system in the prior art. Due to the dense arrangement of heat pipes and the limitation of the arrangement mode, it is impossible to ensure effective heat dissipation at the condensing end of the heat pipes, which will cause The heat of the heat pipe in the central area cannot be effectively used, which will reduce the defect of thermoelectric power generation efficiency, and provide a hot end seat, thermoelectric power generation system, liquid stack and its operation method and application
