Description
Technical field
The invention belongs to reactor system part design technical field, be specifically related to cold and hot pond separating system in the cooling natural circulation bath-type reactor of a kind of liquid heavy metal.
Background technology
The cooling natural circulation bath-type reactor of liquid heavy metal adopts integrated design, all incore components are all immersed in a container, utilize the natural circulation characteristic that liquid heavy metal is good simultaneously, main coolant system adopts Natural Circulation to drive, the probability of happening that has greatly reduced a loop loss-of-flow accident, coolant loss accident, has good inherent safety and economy.Its simple course of work is: cooling medium enters reactor core by cold drop, under the effect of Natural Circulation driving force, after cooling reactor core, import hot pond, the cooling medium in hot pond enters main heat exchanger, transfers heat to secondary circuit cooling medium and imports cold drop, forms the circulation of a circuit cools agent.
In heap, hot separating system is the vitals of the cooling natural circulation bath-type reactor of liquid heavy metal.The cooling natural circulation reactor of liquid heavy metal is divided into the hot pond on top and the cold drop of bottom by hot separating system by cooling medium in primary tank, for reducing hot pond to the heat transmission of cold drop, the temperature difference of maintaining heat pond and cold drop.For the cooling natural circulation bath-type reactor of liquid heavy metal, its hot pond is different with cold drop temperature, cause the cooling medium of primary tank internal upper part and bottom to produce density difference, liquid heavy metal has good natural circulation characteristic simultaneously, thereby a circuit cools agent is produced to Natural Circulation driving force.In heap, the effect of heat insulation of hot separating system will directly determine maintaining of the temperature difference between hot pond and cold drop, directly affect the natural-circulation capacity of reactor and the stability of circulate coolant, thereby affect economy and the inherent safety of liquid heavy metal natural circulation bath-type reactor.
In the cooling pool reactor of existing liquid metal, in heap, hot separating system adopts the hot dividing plate scheme of individual layer steel plate or multilayer steel plates structure more.In the design of China Experiment Fast Reactor, in reactor, horizontal direction adopts the three-ply plate of each interval, the double-layer plate that vertical direction adopts each interval, form hot separating system in heap, this scheme can reduce the temperature difference of hot dividing plate both sides, reduce the thermal stress on hot dividing plate, but the cooling medium that enters hot spacer gap adopts forced circulation, is not suitable for the pool reactor that adopts Natural Circulation to drive.Cold and hot pond separating system in a kind of liquid metal cooling pond formula reactor of China Science Institute HeFei Resource Research Institute's design, rely on the low density gas in hot spacer gap to reach heat separation effect, but still there is the radiant heat transfer between the hot dividing plate of ectonexine in this scheme, hot dividing plate one side of internal layer near hot pond is that liquid metal, a side are rarefied air simultaneously, in hot pond, all liquid metals are all carried on the hot dividing plate of internal layer, larger for hot separator material selection and processing challenge, engineering feasibility is not high.
In the design of the phoenix fast reactor Phoenix of Belgian plumbous bismuth cooled reactor MYRRHA, France and the sodium-cooled fast reactor PFBR of India, hot system for partition wall is only individual layer steel plate, and the thermal stress on steel plate is larger, to material properties, requires high, realize difficulty large, effect of heat insulation is bad.These reactors all adopt and drive circulation simultaneously, and hot pond is conducted heat negligible on the impact of its circulate coolant ability to cold drop.If natural circulation reactor adopts this design, be unfavorable for the temperature difference of maintaining heat pond and cold drop, can reduce the natural-circulation capacity of full heap, affect the thermal efficiency and the stability of a circuit cools agent circulation.
