Background

Spent fuel is spent nuclear fuel subjected to radiation, typically produced by a nuclear reactor in a nuclear power plant. The sealed container for storing the spent fuel is used for storing the spent fuel (assemblies), and the appearance of the sealed container for storing the spent fuel has various design schemes, and particularly, the length of the sealed container for storing the spent fuel has larger difference in order to adapt to different spent fuel assemblies of different power stations. The concrete dry method storage system is used for storing a spent fuel sealed storage container with a spent fuel assembly, and the existing concrete dry method storage system is generally designed according to the maximum value of the active nuclear fuel assembly, and a guide rail structure is adopted inside the existing concrete dry method storage system to support the spent fuel sealed storage container. After the dry storage system is installed, the whole length cannot be adjusted, and when the length of the spent fuel sealed storage container is basically consistent with the support span of the guide rail inside the dry storage system (shown in figure 1), the stress condition of the guide rail is better. When the length of the sealed storage container of the spent fuel also becomes shorter along with the length of the spent fuel assembly, the length of the existing supporting structure cannot be adjusted. The stress of the guide rail is not uniform when the guide rail supports a short sealed storage tank, namely, distributed load is applied to a contact area of the sealed storage tank, the load is suddenly changed in a non-contact area of the sealed storage tank, and the guide rail is suspended without support (shown in figure 2), so that the overall stress condition of the guide rail is complex, and the risk of deformation of the guide rail is high in the middle storage design life.

In the course of realizing the above-mentioned transportation of nuclear fuel assemblies, the inventors found that at least the following problems existed in the prior art:

the supporting structure which is specially suitable for a concrete dry method storage system and is easy to operate and maintain and capable of effectively protecting various guide rail stress working conditions is lacked.

Further, still including setting up the slide rail below the guide rail, second bearing structure sets up on the slide rail, can pass through the slide rail along the guide rail removes.

Further, the second supporting structure comprises an upright post and a bracket positioned at the top end of the upright post, the bracket is of a V-shaped structure with an upward opening, and the bottom of the guide rail is supported by the second supporting structure through the bracket.

Further, a steel plate is arranged at the position, contacted with the bottom of the guide rail, on the bracket, and the steel plate is used for ensuring the strength and form and position tolerance of the contact position of the bracket and the guide rail.

Further, the bottom setting of stand is in on the slide rail, the stand is two, two constitute hollow structure between the stand for increase the air flow, avoid influencing the inside radiating efficiency of concrete dry method storage system.

Furthermore, an active heat dissipation system can be added into the hollow structure between the two upright posts.

Furthermore, the height and the inclination angle of the second supporting structure and the first supporting structure are consistent, so that the guide rails can be horizontally placed in the concrete dry-method storage system.

Further, the second support structure can be equipped with a power source to realize reciprocating movement on the slide rail, and can also realize movement on the slide rail through manual movement.
