Dampening assembly 116 and fuel assembly directly contact, in transportation, 116 available buffer of dampening assembly is extraneous to be applied
To the impulse force of fuel assembly, prevent nuclear fuel from fracture occurring under percussion, certain protective effect is played to fuel assembly；
Meanwhile, dampening assembly 116 goes back the partial pressure that decomposable asymmetric choice net support component 113 is born, it is to avoid 113 stress of support component is excessive and sends out
Raw bending is ruptured.
Additionally, bearing pin 1164 is equipped with the width of the present embodiment support column 1131, bearing pin 1164 is also cross spiral shell
Nail 1163, screw 1163 is further secured on support column 1131, it is to avoid screw 1163 departs from from support column 1131, is strengthened
The fastening of dampening assembly 116 and support column 1131.
As nuclear fuel assembly needs to be monitored its acceleration in transportation, then need to transport in nuclear fuel assembly
Accelerometer 117 is set in defeated container 1, so as to the acceleration of timely observing and controlling nuclear fuel assembly.As shown in figure 1, the present embodiment
Accelerometer 117 is arranged on the outer wall of top cover 112, accelerometer 117 is examined by need not so opening top cover 112
Look into, it is more simple and easy to do for operator.
In an additional preferred embodiment, as shown in figure 3, accelerometer 117 is can also be provided on the inwall for renovating 1112.
When renovating 1112 and being located at open position, the whether normal work of accelerometer 117, without the need for open top cover 112 again, letter just can be checked
Operating procedure is changed.
Additionally, as shown in Figure 4 and Figure 5, in order to meet the transport of different size nuclear fuel, in some other preferred enforcement
In example, support component 113 includes three or a support column 1131.Refering to Fig. 4, the support component 113 includes three support columns
1131, one of support column 1131 is located at the center of top cover 112, and two other 1131 arranged for interval of support column is in top cover 112
Diagonal on, such setting can ensure stable support of the support component 113 to dimension nuclear fuel assembly.
As shown in figure 5, support component 113 includes a support column 1131, the support column 1131 is arranged in top cover 112
The heart, to fix the nuclear fuel assembly of dimension.It should be noted that when the screw on top cover 112 unassembled support column
When 1131, need to be blocked with the bolt 122 of turret head.
When support component 113 includes a support column 1131, in order to increase connecing for support column 1131 and nuclear fuel assembly
Contacting surface is accumulated, and strengthens the stability that support column 1131 is fixed, as shown in fig. 6, the bottom of the support column 1131 is set in a bottom surface
In the larger base 118 of product.The bottom of base 118 is provided with rubber blanket 119, can reduce the vibrations in transportation to fuel stack
The impact of part.Further, in order that support column 1131 is more stably arranged in base 118, the bottom of support column 1131 with
And its with the contact surface of base 118 on, be respectively equipped with spring washer 120 and rubber washer 121.
It can be seen that, nuclear fuel assembly shipping container of the present utility model, top cover are overall structure and are removably connected with pedestal
Connect, after top cover dismounting, fuel assembly lifting space is bigger；The setting of accelerometer position, is easy to operator to accelerometer
Check；Support component is fixedly connected with top cover, and support component is big by force intensity, stably can provide support for fuel assembly,
