The utility model provides a system for filling and discharging sodium for main container of sodium cooled fast reactor with simple structure, low price and convenient disassembly which not only can fill sodium for the main container, but discharge the sodium.
Description
Technical field
The utility model relates to a kind of device of carrying liquid, particularly a kind of system of filling row's sodium to the sodium-cooled fast reactor primary tank.
Background technology
Sodium-cooled fast reactor with liquid metal sodium as catalyst carrier, in the world Jue Dabufen fast reactor also be with liquid metal sodium as catalyst carrier, still, the present fast reactor known to the whole world just, all has only the function of filling sodium to the reactor primary tank, not the function that sodium in the reactor primary tank is discharged.Cause shutdown in case have an accident, because the sodium in the primary tank can not be discharged, not observe concrete situation, but can only be the origin cause of formation of inferring accident according to the variation of measurement data such as temperature, pressure, exist a lot of uncertain factors, so be difficult to the origin cause of formation of the accident that analyzes very accurately.And known to fast reactor all be directly to fill sodium to the reactor primary tank by secondary circuit, with reactor all is to isolate by valve, the pipeline of sodium refilling system also is connected with it when reactor operation, and is also not exclusively independent between two systems, brings hidden danger to reactor operation.
Summary of the invention
The utility model has overcome deficiency of the prior art, provides a kind of and can fill sodium to primary tank and can arrange the sodium-cooled fast reactor primary tank simple in structure, economic, for convenience detach of sodium again and fill row's sodium system.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
This device comprises storage sodium jar, electromagnetic pump, valve etc., and storage sodium jar is connected with the electromagnetic pump inlet by valve, and the electromagnetic pump outlet links to each other with two sleeve pipes by valve, and two sleeve pipes are connected with primary tank; Two sleeve pipes also are connected with the electromagnetic pump inlet by valve, and the electromagnetic pump outlet is connected with storage sodium jar by valve.
In order to adapt to the needs of Chinese sodium-cooled fast reactor inner space and structure, the utility model is all right: described pair of sleeve pipe is connected with detachable pipeline section, and described storage sodium jar is three storage sodium jars.Described connection is welding.
Compared with prior art, the beneficial effects of the utility model are: this device has the function that sodium in the reactor primary tank is discharged, can be during because of breakdown at reactor with the sodium discharge section in the reactor primary tank until exposing combustion elements, can directly observe out the have an accident state of each parts in the back heap of reactor, thereby can be correct find out reason, improve the design of fast reactor.This device is connected with the reactor primary tank by detachable pipeline section, can easily this pipeline section be removed when normal reactor operation, and native system safety and reactor are disconnected, and has guaranteed the safe operation of reactor.
Description of drawings
The structural drawing of Fig. 1 system
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
This device is according to the needs of fast reactor inner space and structure, three storages of preferred use sodium jars 1,5,6 are connected with electromagnetic pump 9 inlets by pipeline and valve 10,12,14 respectively, electromagnetic pump 9 outlets are connected with two sleeve pipes 3 by valve 8 and pipeline, two sleeve pipes 3 are connected with detachable pipeline section 4 and are connected with reactor primary tank 2, two sleeve pipes 3 are connected with electromagnetic pump 9 inlets by valve 7 and pipeline, and electromagnetic pump 9 outlets are connected with storage sodium jar 1,5,6 by pipeline and valve 11,13,15.
Before the reactor operation, need in reactor primary tank 2, fill sodium.
At first open corresponding valve 10,8, and simultaneously to the 1 inflation pressurization of storage sodium jar, sodium in the storage sodium jar 1 is extruded, when sodium reaches certain liquid level in electromagnetic pump 9, open electromagnetic pump 9, sodium is delivered in the reactor primary tank 2, when storage sodium jar 1 sodium liquid reaches minimum liquid level with electromagnetic pump 9, sodium liquid level meter is reported to the police, and closes respective valves 10.12 pairs of reactor primary tanks 2 of respective valves of opening storage sodium jar 5 then fill sodium, and when storage sodium jar 5 sodium liquid reached minimum liquid level, sodium liquid level meter was reported to the police, and closes respective valves 12.Open the respective valves 14 of storage sodium jar 6 at last and fill sodium to reactor primary tank 2, when filling sodium and reach reactor primary tank 2 and require, valve-off 8,14 and electromagnetic pump 9.And pass through detachable pipeline section 4 this device is removed, at this moment reactor can safe operation.
Out of service when reactor, when needing to check the operating mode of each parts of reactor, need the sodium of discharging reactor primary tank 2.
At first native system is connected with reactor primary tank 2 by detachable pipeline section 4, start native system, open respective valves 7, utilize the pressure of sodium pond top blanketing gas the sodium in the reactor primary tank 2 to be pressed out to the inlet of electromagnetic pump 9, open valve 11, start electromagnetic pump 9, beginning is to 1 li row of storage sodium jar sodium, waits to store that liquid level reaches mxm. in the sodium jar 1, open valve 13, valve-off 11 is arranged sodium in storage sodium jar 5, when liquid level reaches mxm. in storage sodium jar 5, open valve 15 valve-off 13 simultaneously, in storage sodium jar 6, arrange sodium,, close all valves and electromagnetic pump 9 until the needs that satisfy the reactor primary tank.
