Abstract
MSR cylindrical separator formula primary tank belongs to MSR technical field.Its iris type structure mainly solves the distribution problem along cylindrical main vessel axis such as nucleic density, neutron flux, power density, burnup caused by fused salt flowing, the burnup of each fused salt thin slice etc. can be made different and along the change of cylinder axis approximate continuous, thus can be in fused-salt medium, the nuclear burning ripple for the stabilization propagated along cylinder axis is formed, the high burnup of fertile material can be realized.Change active region and its neighbouring dividing plate into compact plate-type heat exchanger, heap power output etc. can be improved.Primary tank can also use the wall of heat-exchangers of the plate type formula, and core structure can be made compact and simplified.The reactor core of low pressure operation, what the thin wall barrier formula and wall plate-type heat exchanger of interior logical fused salt or gaseous coolant were technically feasible, but fused salt pile structure can be made to become more complex.The requirement of property when being mainly used in meeting to burn the special special MSR normal operation of depleted uranium or thorium.
Description
Technical field MSR
The primary tank of background technology MSR is its critical component, inside has molted salt nuclear fuel, molten salt coolant, fused salt to increase
Grow material etc..Primary tank can have different shape and structure.The type of cooling has interior cold and cooling type.To realize different work(
With.
The structure of the horizontal positioned elongated cylindrical primary tank of content of the invention MSR, along cylinder axis lateral arrangement every
Plate, fused salt is separated into equal thickness or the thin slice of cylinder of specific thicknesses with several centimeters of the way-board in interval, dividing plate with primary tank
Sealing requirements between wall are not high, and dividing plate can easily move along cylinder axis, to solve to need to move when fused salt expands and reloaded
The problem of dynamic dividing plate, and dividing plate, the one or both ends of cylinder can be readily changed according to the needs of irradiation dose or service life
It can be hemispherical or plane, be provided with close to start end and change dividing plate and discharge fused salt spentnuclear fuel mechanism, the other end has charger
Structure.Fused salt natural circulation cooling in thin slice of cylinder, the nucleic Density Distribution of each fused salt thin slice, neutron flux, power density, combustion
Consumption etc. is different and along the change of cylinder axis approximate continuous, and fused salt virgin material is also easily added in units of thin slice of cylinder
Or spentnuclear fuel is removed, it in the fused-salt type medium of depleted uranium or thorium, can thus form the core for the stabilization propagated along cylinder axis
The active region of combustion wave or the Critical Stability of movement.The high burnup and the high height for putting fission product that fertile material can be realized transmute
Become.When in emergency circumstances or temperature of molten salt exceedes setting value, only need to discharge active region and its neighbouring fused salt, spentnuclear fuel and
The fused salt in virgin material area can still be retained in reactor core, or be discharged in other storage tank, i.e., sectional is discharged.Further development, it can incite somebody to action
The compact plate-type heat exchange of high temperature resistant of active region and its neighbouring dividing plate Evolution Development into the manufacture such as metal or carbon carbon complex
Device, to improve heap power output.Whole dividing plates are not needed all to change iris type heat exchanger into.When nuclear fuel is all in primary tank
And during with the wall heat transfer of primary tank, heat-exchangers of the plate type, this wall plate-type heat can be partly or entirely made in its wall
Exchanger can be single or multiple lift, interior ventilation body or molten salt coolant, can be used for that variously-shaped primary tank to be for example spherical, cylinder
It shape etc., can be also used together with iris type heat exchanger, the primary tank heat exchange area increased considerably, be advantageous to reactor core heat energy
More effectively export.Because reactor core low pressure operation, the thin wall barrier formula heat exchanger and wall of interior logical fused salt or gaseous coolant
Plate-type heat exchanger should be technically feasible, but the structure of MSR can be made to become more complex.
The cylindrical separator formula primary containment structure schematic layout pattern of appended drawings 1.Firing tip is spherical another in figure
Hold as plane.The wall of primary tank can be wall plate-type heat exchanger or common wall, referring to accompanying drawing 2.It is attached
The internal structure layout half-section diagram of Fig. 2 iris type heat exchangers.Bossing between two plates plays water conservancy diversion and support function, stream
Gas body or molten salt coolant in groove.
When embodiment builds special special MSR, the construction of its primary tank will be according to cylindrical separator formula master
The structural requirement manufacture of container, could meet the requirement of the property of the normal operation of special special MSR.Such as realize height
Burnup, long-life etc..
