Face has more stable structure for the storage tube of square, meanwhile, at least two adjacent opposite faces between adjacent storage room,
So that storeroom, which is combined into after modular storage sleeve pipe, has stable structure, Relative sliding between adjacent grid is reduced, enters one
Step increase anti-seismic performance.Exemplarily, the neutron absorber plate is adopted as B4C/Al neutron absorber plates.Compared to fracture toughness
Single boron carbide ceramics absorbing material that is low, being difficult to densified sintering product, B is made by boron carbide and aluminum or aluminum alloy4C/Al neutrons are inhaled
Plate is received, so that the good plasticity and toughness and boron carbide ceramics high intensity, high rigidity, good neutron-absorbing with metallic aluminium are imitated
The advantage of fruit.It is to be appreciated that the use B4C/Al neutron absorber plates are explained only as example to the present invention
Exemplary, any neutron absorber plate, suitable for the present invention.
It is that example is illustrated to be set to section as the storage tube of hexagon using storage tube below.It is to be appreciated that institute
State storage tube and be set to section for hexagon, the storage tube being merely exemplary.
Referring to Fig. 4 A, the schematic diagram of storeroom according to an embodiment of the invention is shown.The storeroom 5 includes
Storage tube 5-1, cladding plate 5-2 and storeroom bottom plate 5-3, the storeroom bottom plate 5-3 are fixedly connected with bottom plate 2, the storage
The top of room 5 is fixedly connected with upper backup pad, by being fixedly connected for each storeroom and bottom plate and upper backup pad, is formed each
Being fixedly connected for storeroom, while further stablizing the structure of storage sleeve pipe, further improves shock resistance.Exemplarily,
The storeroom bottom plate 5-3 is fixedly connected by bolt with the bottom plate 2, compared to using welding manner by storeroom bottom plate with
Bottom plate is fixedly connected, described more stable by the way of bolt is fixedly connected with the bottom plate, not mutability, while also side
Just installing/dismounting.With continued reference to Fig. 4 B, storeroom bottom plate 5-3 passes through bolt hole 5-3- in the schematic diagram of storeroom bottom plate in Fig. 4 B
1 is fixedly connected with bottom plate 2.Exemplarily, limbers is provided with the storeroom bottom plate, with continued reference to Fig. 4 B, the storeroom
It is further opened with limbers 5-3-2 on bottom plate 5-3, the limbers is trapezoidal, evenly around being distributed in the bolt hole 5-3-1 tetra-
Week.The limbers from screen work bottom to be passed through cold water to cool down the fuel in the storeroom.The storeroom
Set limbers to be merely exemplary ground on bottom plate, in the frame structure for possessing multiple storerooms, only can be stored in part
Limbers is set on the bottom plate of room.Exemplarily, carried out at the top of the storeroom by way of welding with the upper backup pad
It is fixedly connected, so as to form continuous seamless structure at the top of screen work, it is ensured that the stability of storage sleeve pipe, and further prevents
Relative sliding under earthquake operating mode between storeroom.Fig. 5 shows showing for screen work bottom plate according to an embodiment of the invention
It is intended to.From figure 5 it can be seen that the bottom plate 5-3 can be consolidated by different bolt hole 5-3-1 form with the bottom plate 2
Fixed connection.
Exemplarily, the neutron absorber plate is arranged between the side wall of the storage tube and cladding plate.With continued reference to figure
4A, in storeroom 5, middle daughter board 5-4 is arranged between storage tube 5-1 side wall and cladding plate 5-2, and the storage tube is set to
When section is at least the storage tube of hexagon, so that each storage tube has at least six neutron absorber plates, neutron is improved
Baffle sets quantity, and neutron absorption capability is substantially increased compared to four storage tubes.
Exemplarily, referring to Fig. 1, the screen work also includes adjustment supporting leg 8, and the adjustment supporting leg 8 is fixed on the screen work
Bottom plate 2 on.Balance integrally-built to the screen work is finely adjusted when the adjustment supporting leg is used to install at the scene, further
