Exhibition and the demand of low-carbon emission reduction, nuclear power are favored by more and more national.In order to further improve the peace of following nuclear power station
Full property and economy, domestic and international nuclear power enterprise and scientific research institution have started the R＆D work of the 4th generation of technology such as nuclear energy system.
Supercritical-Pressure Light Water Cooled Reactor is unique selected water cooled reator in the 4th generation of technology such as nuclear energy system.The current nuclear power technology route of China
Based on presurized water reactor.Therefore from meeting China's future clean energy resource growth requirement and technology continuity, overcritical water-cooled
Heap is a kind of reactor core scheme of the great prospect with security, economy and sustainability.Supercritical-Pressure Light Water Cooled Reactor is due to reactor core
Complex structure, gateway coolant density difference are larger, there is the possibility that out-phase flow instability occurs in reactor core.Supercritical water
The experiment of parallel port flow instability is the important mechanism experiment for studying Supercritical-Pressure Light Water Cooled Reactor flowing instability feature, is used for
The flow instability feature that reflection Supercritical-Pressure Light Water Cooled Reactor is likely to occur under coolant density situation of change.
Prototype Supercritical-Pressure Light Water Cooled Reactor core power is non-uniform Distribution vertically, and this non-uniform Distribution feature can affect to lead to
Road is along the Temperature Distribution of journey, Boundary Layer Characteristics, flow behavior, and then affects the starting point of flow instability phenomenon, unstable
The rules such as property dynamic characteristic.Therefore the flow instability in Experiment of Thermophysics under the conditions of development nonuniform heat flux is needed to grind
Study carefully.At present, the general non-uniform Distribution that power is realized using non-uniform wall thickness method, but this method is for the processing of passage
Manufacture requirements level is very high, and key technology is also rested in offshore company；In addition, this mode is can only obtain for a passage
The power distribution shape of one group of fixation, it is impossible to realize the transient control and orientation adjustment of power distribution, it is impossible to be applied to transient state
In the experimental study of regulatory demand.
Based on this, study and develop and devise a kind of new supercritical water parallel port stepwise adjustable electricity-saving heating method
For simulating prototype Supercritical-Pressure Light Water Cooled Reactor axial power distribution character.
The content of the invention
The technical problem to be solved is existing for unstable to nonuniform heat flux flowing in Experiment of Thermophysics
In qualitatively studying, using non-uniform wall thickness method, the processing and manufacturing level requirement to heating passage is higher, it is impossible to realize to work(
The transient control and orientation adjustment of rate distribution, it is impossible to be applied in the experimental study of transient state regulatory demand.The object of the invention exists
In a kind of Novel supercritical water parallel port stepwise adjustable electricity-saving heating device is provided, conducting copper is installed on heating passage,
The independent heating end of correspondence heating passage area heating is set between adjacent conductive copper bar, is solved and cannot be realized to water cooled reator axle
It is simulated to power distribution characteristics, transient control, the technical problem of orientation adjustment.
The present invention is achieved through the following technical solutions：
A kind of Novel supercritical water parallel port stepwise adjustable electricity-saving heating device, including etc. wall thickness heating passage, heating
At least provided with three conducting coppers on passage, heating module between two neighboring conducting copper, is connected with, heating module includes can
