Description
Technical field
The utility model relates to a kind of passive residual heat removal system for molten salt reactor.
Background technique
Fused salt has the advantages that chemical property stabilization, boiling point height, good heat-transfer etc. are a variety of, uses fused salt for coolant and pottery
The cooling high temperature nuclear reactor of the fused salt of porcelain coated particle fuel element, works under low-voltage high-temperature, there is good inherent safety and extensively
High temperature application, receive the extensive concern of the Nuclear Power circle, the whole world has multiple cooling high temperature nuclear reactors of enterprises' investment fused salts
Exploitation design in.
After reactor generation accident, even if emergency shut-down, still there is part of waste heat persistently to generate, this part of waste heat is comparable
It is also very considerable in a period of time, it needs to be set out by the residual heat removal system being specially arranged to ultimate heat sink.Otherwise, heap
Interior heat accumulation and temperature raising may cause reactor safety barrier failure, cause to release outside radioactivity, serious core is caused to be pacified
Full accident.
Residual heat removal system is divided into active residual heat removal system and passive residual heat removal system, and the difference of the two is,
Active residual heat removal system must rely on external power supply or external action, and passive residual heat removal system does not need external move
Make, fully relies on natural phenomena driving.If in the case where power-off (being lost containing reliable source of power), when power supply cannot restore in time,
Active residual heat removal system just loses the function of discharge residual heat of nuclear core, and then will lead to core meltdown, pressure boundary and containment
Breakage, so that a large amount of hot materials are discharged into environment.In the case where complete power loss, only uses and do not depend on power supply
Passive residual heat removal system can prevent the accidents such as core meltdown, pressure boundary and containment breakage.Thus may be used
See, it is particularly significant to the design and research of passive residual heat removal system.
However, under accident conditions, fuel salt can be discharged into fuel salt storage tank, fuel salt first in traditional molten salt reactor design
It is equipped with residual heat removal system in storage tank, and then by Residual heat removal.Wherein, which changes using a kind of bushing type

In the prior art, the Residual heat removal of high temperature shut-down system cooling for fused salt, has using passive residual heat removal system
The situation of system mainly uses gravity as the driving force of passive system.University of California Berkeley (english abbreviation UCB)
A kind of molten salt reactor buffer salt accident afterheat discharge system is proposed, the structure and working principle of the system is specific as follows: by fused salt
Cooling high temperature is stacked in molten salt pool, and special Residual heat removal heat exchanger is arranged in the molten salt pool, under accident conditions, fused salt
The heat of cooling high temperature nuclear reactor first passes through Residual heat removal heat exchanger transfer to remaining row's fused salt circuit, then by being placed in air cooling tower
Radiator arranges the waste heat that fused salt is absorbed in remaining row's fused salt circuit to atmosphere hot trap.However, the passive residual heat removal system,
Additional molten salt pool need be set, taken up a large area, therefore be unfavorable for the economy of heap.
In summary, there is no in the prior art, occupied area simple for structure it is small for the passive remaining of molten salt reactor
Hot discharge system, therefore seek the technology that the novel passive residual heat removal system for molten salt reactor of one kind is current urgent need to resolve
Problem.
