Description
Technical field
The utility model belongs to nuclear reactor technology field more particularly to a kind of rotation control rod.
Background technique
Control rod is reactor control unit, is made of the very capable material of absorption neutron, can control nuclear fission
Rate；They are for starting reactor, adjusting heap power and shutdown in normal conditions；Under accident conditions, control rod is relied on
The quick underthrust of self gravity makes reactor emergency shut-down in a very short period of time, to guarantee safety.
Existing control rod pair realizes the control to reactor using the transverse movement form for pulling out pumping, but such side
Formula can not quickly and effectively realize adjusting control, especially for the nuclear reactor shutdown under the state of emergency, need to consume longer
Time, cannot achieve rapid adjusting, greatly perplex for nuclear reactor reliability of operation and safety bring.
Utility model content
In order to overcome the shortcomings of art methods, the purpose of this utility model is that propose a kind of rotation control rod,
It can rapidly and effectively realize that the adjusting control of nuclear reactor, operating process are simple；Realize scram function, time-consuming is few,
Control process is uniform and stable, can effectively improve reliability and safety in nuclear reactor operational process.
In order to achieve the above object, the utility model is using technical solution: a kind of rotation control rod, including outer housing and
Inner core, the inner core insert in the inside of outer housing；
The outer housing is the circular casing that window is offered on side wall；The outer surface of the outer housing is absorber layers, institute
The inner surface for stating outer housing is structural material；
The inner core is barred body structure, is circumferentially sequentially arranged at intervals with fuel slug and absorber on the surface of the inner core
The position of block, the fuel slug and absorber block is corresponding with described the window's position.
Further, being disposed at least one window along axial direction on the side wall of the outer housing, it is arranged multiple
Window can reinforce the controllability of regulating effect.
Further, circumferentially offering 3 windows, each window in the same axial region of shell body sidewall
Mouth subtended angle is 50 ° -60 °；Maximum reactivity value and minimal reaction sexual valence can be realized in the angle that inner core only needs to rotate subtended angle
The switching being worth between two states.
Further, the surface of the inner core is provided with 3 fuel slugs and 3 absorber blocks, the fuel slug and suction
The width of acceptor block is identical as window width；It, being capable of save the cost while realizing regulating effect.
Using the technical program the utility model has the advantages that
The utility model can either realize the adjusting of control rod by rotating inner core, can rapidly and effectively realize that core is anti-
The adjusting of heap is answered to control, operating process is simple；Few for the adjustment process time-consuming of nuclear reactor, control process is uniform and stable, energy
Enough effectively improve the reliability and safety in nuclear reactor operational process；Especially in case of emergency, it can be realized quickly
Shutdown function.

Specific embodiment
In order to keep the purposes, technical schemes and advantages of utility model clearer, with reference to the accompanying drawing to the utility model
It is further elaborated.
In the present embodiment, shown in referring to figures 1-3, a kind of rotation control rod, including outer housing 1 and inner core 2, it is described
Inner core 2 inserts in the inside of outer housing 1；
The outer housing 1 is the circular casing that window 11 is offered on side wall；The outer surface of the outer housing 1 is absorber
Layer, the inner surface of the outer housing 1 are structural material；
The inner core 2 is barred body structure, is circumferentially sequentially arranged at intervals with fuel slug 21 on the surface of the inner core 2 and inhales
The position of acceptor block 22, the fuel slug 21 and absorber block 22 is corresponding with 11 position of window.
As the prioritization scheme of above-described embodiment, at least one is disposed with along axial direction on the side wall of the outer housing 1
A window 11, multiple windows 11, which are arranged, can reinforce the controllability of regulating effect.
3 windows 11, each 11 subtended angle of window are circumferentially offered in the same axial region of 1 side wall of outer housing
It is 50 ° -60 °；Maximum reactivity value can be realized in the angle that inner core 2 only needs to rotate subtended angle and minimal reaction is worth two kinds
Switching between state.
The surface of the inner core 2 is provided with 3 fuel slug 21 and 3 absorber blocks 22, the fuel slug 21 and absorber
The width of block 22 and window 11 are of same size；It, being capable of save the cost while realizing regulating effect.
In order to better understand the utility model, primary complete description is made to the working principle of the utility model below:
It rotates inner core 2 and arrives different angle, change material (i.e. the change fuel slug 21 and absorption appeared in circular casing window 11
The ratio that body block 22 exposes), it may be implemented to reactive control.
