The characteristics of precision assembly and Precision measurement.For special reactor, need according to selected fuel assembly type, reactor core display,
The difference of coolant type, reactive control mode etc., designs special control rod guide tubes and bundles structure, had both been able to satisfy its function and has wanted
It asks, and is unable to too complex, reduce the requirement to equipment and technology as far as possible.
Utility model content
The purpose of this utility model is built upon on the basis of Deep Pool Low Temperature Heating Reactor feature, the pile reactivity
Control is controlled using full control rod, and no boron water is adjusted, therefore C&P systems level of confidentiality, quantity are more, all contain in consecutive fuel component
C&P systems, conventional control rod guide tubes and bundles because thereon, lower end surface all lean on flange mutually to fix with screen, the control of adjacent position
The interference of stick guide cylinder mounting flange can not install, and should not use.The utility model provides a kind of control suitable for such heap-type
Stick is oriented to barrel structure, which does not influence the integral installation of reactor, also meets the accuracy requirement of positioning and guiding, structure compared with
It is simple.
To achieve the above objectives, the technical solution adopted in the utility model is: a kind of control rod guide tubes and bundles structure, wherein
Including by pull rod, from top to bottom horizontal stacking is arranged in several pieces of guide plates below hanging basket, the guide plate is equipped with quantity
Adjacent two pieces are arranged in by two counterbores up and down of position consistency in identical, position consistency counterbore, the guide cylinder
Between the guide plate, the consistent guide cylinder in upper and lower position is configured to the guide channel by control rod.
Further, the pull rod is several, is arranged at intervals at the edge of the guide plate, and perpendicular to the guiding
Plate.
Further, the top of the pull rod is connected by nut with the hanging basket；The bottom end of the pull rod passes through screw
It is connected with the guide plate of the bottom.
Further, the guide cylinder is equipped with several first through hole for by coolant.
Further, the upper and lower surfaces of the counterbore are equipped with the step that can accommodate the guide cylinder.
Further, the hanging basket is equipped with the second through-hole identical as the quantity of the counterbore, position consistency, for passing through
The control rod.
Further, the height of the whole guide cylinder between two pieces of adjacent guide plates is consistent.
The beneficial effects of the utility model are as follows:
1. conventional type guide cylinder can be overcome because of its flange using control rod guide tubes and bundles structure provided by the utility model
Interference can not install fixed defect, and the up and down motion for C&P systems (C&P systems include several control rods) provides
Reliable positioning and guiding, C&P systems total travel frictional force in control rod guide tubes and bundles structure is negligible, while can
Reduce fluid to impact the transverse flow of C&P systems；
2. control rod guide tubes and bundles structure provided by the utility model is used, in structure, it is only necessary to consider precision machined
Difficulty, no-welding-seam can save the requirement to precision welding, and the assembly of the relatively conventional pattern guide cylinder of assembly work is simpler.
