[0002] As a clean energy source, nuclear energy offers unique advantages and development potential in reducing coal consumption, effectively minimizing greenhouse gas emissions, and alleviating energy transportation pressures. It is a crucial energy component for achieving the goals of carbon peak and carbon neutrality. In addition to traditional power generation, high-temperature gas-cooled reactors (HTGRs) have a wide range of applications, including district heating, industrial heating (and cooling), seawater desalination, and nuclear hydrogen production.

[0003] Currently, there are two main approaches to utilizing nuclear energy in high-temperature reactors. One is to remove heat from the core through helium, transfer the heat from the helium to water vapor through a steam generator, and generate high-temperature, high-pressure water vapor for nuclear energy utilization. The other is to use the hot helium removed from the core to directly drive a helium turbine, and use the waste heat for comprehensive nuclear energy utilization. However, both of these approaches require energy conversion, which results in heat loss during the conversion process, hindering efficient energy utilization. Furthermore, the direction of nuclear energy utilization is not scalable. Therefore, a scalable and applicable arrangement method for utilizing nuclear energy using direct helium supply from a high-temperature gas-cooled reactor was developed. Summary of the Invention

[0026] Example 1

[0027] Reference Figure 1-Figure 2 , provides a scalable high temperature gas cooled reactor 100 helium direct supply nuclear energy utilization method, including,

[0028] The high-temperature gas-cooled reactor 100 has an expansion module 200 connected to its outlet end. The medium in the high-temperature gas-cooled reactor 100 can enter the expansion module 200, and the expansion module 200 can absorb the heat carried by the medium entering the expansion module.

[0029] In this embodiment, the medium extracted from the high-temperature gas-cooled reactor 100 is preferably helium. The helium takes out the heat generated in the high-temperature gas-cooled reactor 100 and enters the expansion module 200. The medium exchanges heat in the expansion module 200, and the heat generated by the high-temperature gas-cooled reactor 100 is directly supplied to the expansion application module through helium as a heat carrier, thereby utilizing the heat in the high-temperature gas-cooled reactor 100.

[0030] Furthermore, the outlet of the expansion module 200 is connected to a helium heater 300, and the outlet of the helium heater 300 is connected to the high-temperature gas-cooled reactor 100; the medium in the expansion module 200 passes through the helium heater 300 and enters the high-temperature gas-cooled reactor 100 again;

[0031] By setting up the helium heater 300 , the helium in the expansion module 200 is heated in the helium heater 300 and then enters the high-temperature gas-cooled reactor 100 , where the used helium is preheated and reused.

[0032] Furthermore, the outlet of the high-temperature gas-cooled reactor 100 is connected to two sets of pipelines, one set of pipelines is connected to the expansion module 200, and the other set of pipelines is connected to the helium heater 300;

[0033] The two sets of pipelines are set up so that part of the helium is directly used for the expansion application module and returns to the helium heater 300 after use. The other part of the helium is directly supplied to the helium heater 300 to heat the helium entering the helium heater 300 from the expansion application module. After the two parts of helium are mixed, they are sent to the high-temperature gas-cooled reactor 100 for heating, forming a helium circulation system.

[0034] Furthermore, a helium blower 400 is provided between the helium heater 300 and the high-temperature gas-cooled reactor 100 ; the helium blower 400 can pressurize the helium passing through the pipeline so that the helium can better enter the high-temperature gas-cooled reactor 100 .

[0035] Furthermore, a replenishing mechanism 500 is provided on the pipeline connecting the expansion module 200 and the heater; helium may partially leak when flowing in the pipeline, and the replenishing mechanism 500 can replenish the helium in the system to ensure stable operation of the system.

[0036] The direct supply of helium reduces heat loss during transmission and conversion, improving the energy efficiency of the high-temperature gas-cooled reactor. Helium, as a clean heat carrier, reduces environmental pollution. By improving the utilization efficiency and scalability of nuclear energy, energy costs are reduced and economic benefits are improved. The system has a simple design and compact structure, which reduces floor space, saves purchase costs, and improves equipment reliability.

[0037] Example 2

[0038] Reference Figure 1-Figure 2 ,This embodiment is different from the first embodiment in that: the expansion module 200 is a system with high-temperature and high-pressure steam requirements, and the expansion module 200 can be provided in multiple groups;

[0039] In this embodiment, each system with a high-temperature and high-pressure steam demand can become an expansion module 200. The expansion modules 200 can be used individually or in combination when the steam flow, pressure, and temperature are met. Multiple groups of expansion modules 200 are arranged in parallel when used.

[0040] Preferably, the expansion module 200 includes industrial park applications, hydrogen production, residential heating, seawater desalination, petrochemical heavy oil thermal recovery, steel smelting, pharmaceutical park applications, etc.

[0041] The arrangement method of the expansion module 200 in this embodiment has good scalability. When a certain expansion application module needs to be added, a module is directly added, and the use of other application modules is not affected. The expansion application modules can be increased or decreased according to needs, and can be flexibly adapted to different application scenarios.

[0042] The rest of the structure is the same as that of Example 1.

[0043] Example 3

[0044] Reference Figure 1-Figure 2 , this embodiment is different from the above embodiment in that: the replenishing mechanism 500 includes a gas cylinder group 501 connected to the pipeline, and a helium gas replenishing blower provided between the gas cylinder group 501 and the pipeline;

[0045] The gas cylinder group 501 includes multiple groups of helium cylinders. The helium cylinder group 501 is used to store high-pressure helium to provide the required helium during system operation. In the event of helium supply interruption or increased demand, the helium cylinder group 501 can serve as an emergency backup to ensure continuous and stable operation of the system. The gas cylinder group 501 also includes a pressure regulating device to ensure that the helium has an appropriate pressure when it is delivered to the system.

[0046] The helium supply blower 502 is used to replenish helium into the pipeline to maintain the helium pressure and flow required by the system. During system operation, the helium supply blower 502 can adjust the helium flow rate according to actual needs to adapt to different working conditions. When the helium supply is insufficient, the helium supply blower 502 can respond quickly to replenish helium to ensure stable operation of the system.

[0047] Furthermore, the replenishment mechanism 500 further includes a helium storage tank disposed between the gas cylinder group 501 and the helium supply blower;

[0048] A helium purification device 504 is provided between the gas cylinder group 501 and the helium storage tank;

[0049] The helium purification device 504 is used to remove impurities in the helium, such as moisture, oil, dust, and other gaseous impurities, to ensure the purity and quality of the helium. By purifying the helium, wear and corrosion of the equipment in the system can be reduced, extending the service life of the equipment. Pure helium can improve the heat exchange efficiency, thereby improving the thermal efficiency of the entire system.

[0050] The helium storage tank is used to store a certain amount of helium for use during system operation. The storage tank can serve as a buffer between the system and the helium cylinder assembly 501 to balance fluctuations in helium supply and demand. The storage tank helps stabilize the helium pressure and ensures stable operation of the system under different working conditions.

[0051] The gas replenishment mechanism ensures the stable operation and high efficiency of the high-temperature gas-cooled reactor 100 helium direct supply system. Through the coordinated work of multiple components, it can realize the storage, purification, supply and regulation of helium to meet the high-temperature gas-cooled reactor 100's demand for helium.

[0052] The rest of the structure is the same as that of Example 2.
