[0002] Energy supply often faces significant challenges in areas severely impacted by environmental factors, such as islands, areas prone to sudden geological disasters, and deserts. Traditional energy supply methods are often constrained by imperfect supply networks and unpredictable weather conditions, leading to unstable and unreliable energy supply. To address this issue and ensure a stable, reliable, and secure energy supply in these areas, heat pipe high-temperature reactors have become a highly sought-after solution.

The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0041] Example 1

[0042] 1 and 2 , which are a first embodiment of the present invention, a heat pipe integrated high temperature reactor is provided, which includes a protection unit 100 : including a pressure vessel 101 ;

[0043] The reactor unit 200 includes a reactor compartment 201 and a plurality of fuel grid element assemblies 202 disposed in the reactor compartment 201;

[0044] The heat exchange unit 300 includes a heat exchange chamber 301, a first partition 302 disposed above the stack chamber 201, and a heat transfer pipe 303 disposed in the heat exchange chamber 301;

[0045] The steam generating unit 400 includes a steam chamber 401, a second partition 402 disposed above the heat exchange chamber 301, water inlet pipes 403 disposed on both sides of the steam chamber 401, and a steam outlet pipe 404 disposed above the steam chamber 401;

[0046] The control unit 500 includes a large rotating hub 501 , a small rotating hub 502 disposed on one side of the large rotating hub 501 , a rotating disk 503 disposed at the bottom of the large rotating hub 501 , and a telescopic rod 504 disposed on one side of the rotating disk 503 .

[0047] It should be noted that the pressure vessel 101 is a container used to store and contain the working medium and fission products in the high-temperature heat pipe reactor. It has extremely high strength, pressure resistance and high temperature tolerance, and is generally made of special alloy materials such as niobium alloy, nickel-based alloy, etc.

[0048] Preferably, the pressure vessel 101 contains a steam generating unit 400, a heat exchange unit 300, a reactor unit 200 and a control unit 500 from top to bottom. These four modules are integrated in the pressure vessel 101 and separated by high-strength partitions, and the partition material is consistent with the material of the pressure vessel 101.

[0049] Example 2

[0050] 1 to 7 , a second embodiment of the present invention is shown, which differs from the first embodiment in that: a stack compartment 201, a heat exchange compartment 301, and a steam compartment 401 are sequentially disposed within a pressure vessel 101; the pressure vessel 101 further comprises a hub cavity 101a disposed on one side of the stack compartment 201, a turntable compartment 101b disposed at the bottom of the pressure vessel 101, and a transmission compartment 101c disposed below the turntable compartment 101b;

[0051] The transmission compartment 101c includes a hinge rod 101c-1 provided on one side thereof.

[0052] The fuel cell assembly 202 includes a core 202a and a heat pipe 202b disposed outside the core 202a.

[0053] The ventilation groove 202a extends through the through hole 202c.

[0054] The heat pipe 202b includes a heat source end 202b-1, a condensation end 202b-2 disposed on one side of the heat source end 202b-1, and a heat buffer rod 202b-3 disposed in the heat pipe 202b.

[0055] The heat pipe 202 b passes through the first partition 302 , connecting the stack compartment 201 and the heat exchange compartment 301 .

[0056] The heat transfer pipe 303 passes through the second partition plate 402 and connects the heat exchange chamber 301 and the steam chamber 401 .

[0057] The large rotating hub 501 includes an absorber 501a provided on one side thereof, a cam 501b provided on one side of the large rotating hub 501, and a first latch 501c provided on one side of the cam 501b;

[0058] The small rotating hub 502 includes a second latch 502a disposed at the bottom thereof.

[0059] It should be noted that in the pressure vessel 101, the heat exchange compartment 301 and the steam compartment 401 are circular and through-hole shaped, while the stack compartment 201 is opened into a regular hexagonal through-hole shape. The hub cavity 101a is a 3 / 4 circular through hole that passes through to the turntable compartment 101b. It is specifically divided into a large hub cavity opened in the middle of the six sides of the hexagon of the stack compartment 201, and a small hub cavity opened at the six corners of the hexagon. 1 / 4 of the hub cavity 101a opens toward the center of the stack compartment 201. The large hub cavity contains a large rotating hub 501, and the small hub cavity contains a small rotating hub 502.

[0060] Preferably, the rotating hub body is composed of an absorber 501a and graphite on the periphery. The absorber 501a is made of boronized carbon (B4C) material. The production of neutrons by fission in a nuclear reactor is an important component of the reaction process, and boronized carbon has a very high neutron absorption cross-sectional area and can effectively absorb neutrons, thereby controlling the nuclear fission reaction rate. The cam 501b is fixedly installed at one end of the rotating hub. The raised center of the cam 501b of the large rotating hub 501 is fixedly installed with a first pin 501c, and the raised center of the cam 501b of the small rotating hub 502 is fixedly installed with a second pin 502a. The cam 501b drives the rotating hub to rotate so that its absorber 501a is exposed in the reactor compartment 201. The exposed area of ​​the absorber 501a can be controlled by the rotation angle of the cam 501b, thereby controlling the reaction rate of the reactor.

[0061] Preferably, the fuel fence assembly 202 is composed of a uniform array of cores 202a and heat pipes 202b, the array arrangement of which is shown in Figure 3. Each heat pipe 202b is shared by six cores 202a, and the heat of each core 202a is transmitted to the heat exchange chamber 301 by three adjacent heat pipes 202b. In the core 202a, the center is a columnar TRISO fuel interval, which is filled with a graphite matrix and contains dispersed TRISO fuel particles. TRISO particles are commonly used fuel designs for high-temperature reactors. These particles serve as the first barrier to contain radioactive products. The TRISO fuel interval is coated with graphite material. This interval is a graphite shell interval, and the graphite cladding serves as the second barrier to contain radioactive products. The two sections together constitute the fuel elements, which are prismatically agglomerated and stacked in the longitudinal direction of the core 202a. The heat pipe 202b is a single integral piece in the longitudinal direction, starting from the core 202a, passing through the first partition 302, and inserted into the intermediate heat exchange chamber 301 for heat input.

[0062] Preferably, the heat exchange chamber 301 is filled with metallic lead. The high core temperature causes the metallic lead within this chamber to be molten. The uneven temperature distribution of the heat pipes can cause the molten lead to flow and turbidity, making the molten lead temperature distribution more uniform. This configuration can further uniformize the radial temperature distribution, reduce radial power peaks and temperature peak factors, and mitigate the impact of uneven temperature distribution on reactor safety and economic efficiency. Lead is a good shielding material, effectively reducing the impact of radiation emitted by the core 202a on the working fluid water within the steam chamber 401, thereby reducing the discharge of nuclear wastewater after the reactor is operational. The intermediate heat exchange chamber 301 also adds a safety barrier to the core. In the event of a severe accident such as a partition rupture or loss of coolant in the steam generator compartment, the molten lead cools and solidifies, protecting the core from fission product leakage. Another set of heat transfer pipes 303 is provided within the heat exchange chamber 301, alternating with the heat pipes 202b connected to the core 202a. The molten lead transfers heat to the steam chamber 401 through this second set of heat transfer pipes 303.

[0063] Preferably, a second partition 402 is provided between the heat exchange chamber 301 and the steam chamber 401, and the heat transfer pipe 303 passes through the second partition 402 to transfer heat to the steam chamber 401. The water inlet pipe 403 is fixedly installed on both sides of the steam chamber 401 and is symmetrically distributed. The water inlet pipe 402 passes through the steam chamber 401. The heat transfer pipe 303 conducts heat from the heat exchange chamber 301 to heat the working medium water in the steam chamber 401, causing the water to boil and change phase to produce high-temperature steam, which is output through the steam outlet pipe 404 above. Finally, the steam is converted into energy and collected by an external steam turbine.

[0064] During normal operation, this integrated small-scale prismatic high-temperature heat pipe reactor can be transported to its target location by vehicle, rail, or air, connected via a pre-configured pipeline system. After the reactor is started, fission energy is transferred to the steam generator system via heat pipes and an intermediate heat exchange system. This heats the working fluid, converting it into high-temperature steam energy for use by the target device, serving as a power supply unit. By connecting to an external piping system to output steam power, the system eliminates the need for an additional heat conversion system, reducing equipment and improving stability, reliability, and cost-effectiveness.

[0065] Example 3

[0066] 1 to 9 , a third embodiment of the present invention is shown, which includes the above two embodiments and differs from the above two embodiments in that: the turntable 503 further includes a second track 503 a provided on its surface, a first track 503 b provided on one side of the second track 503 a, a protruding plate 503 c provided on the bottom of the turntable 503, and a hinged joint 503 d provided on one side of the protruding plate 503 c.

[0067] The second track 503a cooperates with the first latch 501c;

[0068] The first track 503b cooperates with the second latch 502a.

[0069] The telescopic rod 504 includes a fixed end 504a and a movable end 504b;

[0070] The fixed end 504a cooperates with the hinge rod 101c-1;

[0071] The movable end 504b cooperates with the hinged end 503d.

[0072] It should be noted that the turntable 503 is movably installed in the turntable cabin 101b, and the telescopic rod 504 is hingedly installed in the transmission cabin 101c.

[0073] Preferably, as shown in Figures 7 and 9, the turntable 503 is provided with six pairs of second tracks 503a distributed in a circumferential array and connected thereto, and between every two first tracks 503b there is also a first track 503b evenly distributed therebetween, the second track 503a is engaged with the first latch 501c at the bottom of the large rotating hub 501, the first latch 501c is inserted into the second track 503a, and similarly, the second latch 502a at the bottom of the small rotating hub 502 is inserted into the first track 503b. When the turntable 503 rotates counterclockwise, the first latch 501c will rotate clockwise along the second track 503a and simultaneously drive the large rotating hub 501 to rotate, and the second latch 502a will also rotate synchronously clockwise along the first track 503b to drive the small rotating hub 502 to rotate, and the absorber 501a is controlled by the rotating torque. The exposed area controls the reaction rate of the reactor. When the turntable 503 rotates clockwise, the first pin 501c and the second pin 502a rotate counterclockwise. At this time, the two have different motion trajectories. The second track 503a is flat, and the first track 503b also moves in a circular motion, which will cause the large rotating hub 501 to not rotate and the small rotating hub 502 to rotate. Through this setting, the rate control of the reactor can be refined into two parts. When the turntable 503 rotates counterclockwise, the two rotating hubs move at the same time. At this time, the control range is large and the adjustment is convenient, but the adjustment accuracy is low. It is suitable for reactor control or shutdown that requires immediate large-scale adjustment. When the turntable 503 rotates clockwise, only the small rotating hub rotates. At this time, the control range is small, but the adjustment accuracy is high, which is suitable for smaller rate adjustments during the operation of the reactor.

[0074] Preferably, a frustum-shaped convex plate 503c is fixedly connected to the bottom of the turntable 503, and the convex plate 503c extends from the turntable cabin 101b to the transmission cabin 101c. A hinged joint 503d is fixedly connected to the surface of the convex plate 503c, and the hinged joint 503d is hinged to the movable end 504b of the telescopic rod 504, and the fixed end 504a of the telescopic rod 504 is hinged to the hinged rod 101c-1. The telescopic rod 504 is electrically driven or hydraulically driven, and the turntable 503 can be driven to rotate clockwise or counterclockwise through the telescopic feed amount to control the large and small rotating hubs.

[0075] When in use, it is transported to the target location by vehicle, rail, air, etc., and connected through a preset pipeline system. After the device is installed, it can start working. The core 202a acts as a heat source to generate thermal energy through fission reaction. The heat generated by the core is transferred to the molten lead in the heat exchange chamber 301 through the heat pipe 202b, and then the heat is transported to the steam chamber through the heat transfer pipe 303 to heat the working water to generate high-temperature steam. Finally, the steam thermal energy is converted into energy through the steam turbine to supply energy to the target system.

[0076] In summary, the present invention adopts a new reactor core design, which makes it compact and modular by integrating the reactor core 202a, the intermediate heat exchange system and the evaporator system, and can be quickly deployed and operated, thereby solving the problem of difficult and slow energy supply in emergency situations; the reactor core 202a is a triangular prism, and the heat pipes 202b are arranged in a triangular array outside the core 202a, which can fully absorb the energy generated by the core 202a. By adding a heat exchange chamber filled with molten lead between the core compartment and the steam compartment, due to the shielding properties of the lead, the impact of the radiation released by the core 202a on the working fluid water in the steam compartment 401 can be effectively reduced. The heat exchange chamber 301 also adds a safety barrier to the core. In the event of a severe accident, such as a diaphragm rupture or loss of coolant in the steam generator compartment, the molten lead cools and solidifies, preventing the leakage of fission products in the core 202a. Furthermore, traditional control rods are replaced by boron carbide rotating hubs placed at varying intervals. The position of the boron carbide material is controlled by a bottom turntable 503, thereby controlling the neutron flux density in the reflector layer and, consequently, the core reactivity. The core design meets Generation IV reactor standards, utilizing TRISO fuel particles and a graphite matrix as fuel elements, with graphite as the moderator. The high thermal feedback coefficient of this fuel and the high heat capacity of the graphite components ensure that even in the event of a severe accident, even if the control system fails completely, the reactor system can still automatically shut down due to high temperatures, ensuring safety in the event of an accident.
