Abstract
This novel upper grid plate that belongs to, concretely relates to fuel assembly upper grid plate. It includes upper grid plate barrel, upper grid plate bottom plate to and set up at the upper grid plate barrel, big pterygoid lamina and little pterygoid lamina between the upper grid plate bottom plate, wherein the upper grid plate barrel be the cylinder part, and the upper grid plate bottom plate be the regular hexagon part, and the coaxial setting of geometric centre of this upper grid plate barrel and upper grid plate bottom plate sets up 2 pterygoid laminas at every edge of upper grid plate bottom plate, and wherein the setting is at the big pterygoid lamina that is of apex angle, and the setting is at the little pterygoid lamina that is of edge. This neotype effect is: using the upper grid plate of this application, going up and use big pterygoid lamina and the connection of winglet board between the lower plate, joint strength is markedly increased, the bellied phenomenon in bottom surface in the conventional art can not appear.
Description
Technical field
Basis is novel belongs to upper grid plate, is specifically related to a kind of fuel assembly upper grid plate.
Background technology
Upper base is one of key components of high burnup nuclear fuel assembly, has the irreplaceable functions such as lifting, control rod entrance, bumper and absorbing shock.
The upper grid plate of fuel assembly is the important component part of presurized water reactor nuclear fuel, has the important function such as positioning and guiding pipe, bearing assembly weight.Panel is as shown in Figure 1 traditionally, and this upper grid plate includes parallel two base plate, small one and large one, connected by metal rack between the two, form the structure of similar round platform.This upper grid plate has the disadvantage that: 1. the bottom plate heights on top is less, it is impossible to the various parts in protection upper grid plate；2. being made by metallic plate at sidewall, when there is external pressure, central plate can protrude, and causes base plate uneven, affects current performance further, ultimately result in heat dispersion difference, cause the potential safety hazard of fuel assembly；3. if it occur that above-mentioned central plate situation about protruding, wanting to even up this projection, required technical matters too complex, the manpower and materials of input and time are all too many, and again make a upper grid plate and there is a need to put into more human, financial, and material resources, cause crag-fast situation.
Summary of the invention
This novel pin is to prior art defect, it is provided that a kind of spring washer manufacturing process.
This novel technical scheme is: a kind of fuel assembly upper grid plate, wherein, including upper grid plate cylinder, upper grid plate base plate, and it is arranged on upper grid plate cylinder, big wing plate between upper grid plate base plate and small wing, wherein upper grid plate cylinder is cylindrical component, and upper grid plate base plate is regular hexagon part, the geometric center of this upper grid plate cylinder and upper grid plate base plate is coaxially disposed, arranging three wing plates on each limit of upper grid plate base plate, being provided with at drift angle is big wing plate, and being arranged on limit is small wing.
A kind of fuel assembly upper grid plate as above, wherein, described big wing plate and small wing are right angled triangle part, arrange some through holes on big wing plate and small wing.
A kind of fuel assembly upper grid plate as above, wherein, the height of described upper grid plate cylinder is at least 80 centimetres.
A kind of fuel assembly upper grid plate as above, wherein, described upper grid plate cylinder arranges through hole.
This novel effect is: use the upper grid plate of the application, uses big wing plate and small wing to connect between upper and lower bottom plate, and bonding strength substantially increases, and does not have the phenomenon that in conventional art, bottom surface is protruding；Upper plate becomes tube structure, adds height, has good effect to protecting its interior part；Adding through hole on upper grid plate cylinder, this through hole plays location and interconnection function in subsequent installation process, facilitates the carrying out of follow-up work.
Accompanying drawing explanation
Fig. 1 is the structural representation of conventional art upper grid plate；
Fig. 2 is the structural representation of the application upper grid plate；
Fig. 3 is the top view of Fig. 2.
In figure: 1. upper grid plate cylinder, 2. big wing plate, 3. small wing, 4. upper grid plate base plate.
Detailed description of the invention
A kind of fuel assembly upper grid plate, including upper grid plate cylinder 1, upper grid plate base plate 4, and be arranged on upper grid plate cylinder 1, big wing plate 2 between upper grid plate base plate 4 and small wing 3, wherein upper grid plate cylinder 1 is cylindrical component, upper grid plate base plate 4 is regular hexagon part, and the geometric center of this upper grid plate cylinder 1 and upper grid plate base plate 4 is coaxially disposed, and arranges 2 wing plates on each limit of upper grid plate base plate 4, being provided with at drift angle is big wing plate 2, and being arranged on limit is small wing 3.
Arranging 2 wing plates on described each limit to refer to, there are 2*0.5 big wing plate, 1 small wing in every limit.
Described big wing plate 2 and small wing 3 are right angled triangle part, arrange some through holes on big wing plate 2 and small wing 3.
The height of described upper grid plate cylinder 1 is at least 80 centimetres, for protection setting part in the middle of the upper grid plate.(conventional art upper grid plate cylinder height is approximately 50 centimetres)
Arranging through hole on described upper grid plate cylinder 1, this through hole plays location and interconnection function in subsequent installation process.
Described upper grid plate cylinder 1 and the size of upper grid plate base plate 4 manufacture as requested.
