Abstract

The invention discloses a hot end seat, a thermoelectric power generation system, a liquid reactor, an operation method of the liquid reactor, and application of the thermoelectric power generation system. The hot end seat is used for being matched with the condensation ends of reactor core heat pipes in a liquid reactor, wherein the positions of the tops of the condensation ends of the reactor core heat pipes are sequentially increased from outside to inside, the condensation ends of the reactor core heat pipes are divided into the first to Nth areas from outside to inside, the hot end seat comprises hot end sleeves from the first layer to the Nth layer from bottom to top, the outer diameters of the hot end sleeves are decreased layer by layer from bottom to top, the hot end sleeve of thehot end seat corresponds to the area of the condensation end of the reactor core heat pipe, the hot end sleeve is provided with a center body and an outer edge body surrounding the center body, the center body is used for passing through the reactor core heat pipe in the areas corresponding to other layers above the layer, the outer edge body is provided with a reactor core heat pipe channel, andthe reactor core heat pipe channel is used for containing the condensation end of the reactor core heat pipe in the area corresponding to the layer. According to the hot end seat, heat of the reactorcore heat pipe can be smoothly brought out, so that local hot spots are avoided, and the heat utilization rate and the thermoelectric power generation efficiency are improved.

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
