技术领域 technical field
本实用新型涉及核电厂燃料装卸及贮存领域，具体是一种用于地下核电站的长距离燃料传输通道。 The utility model relates to the field of fuel handling and storage in nuclear power plants, in particular to a long-distance fuel transmission channel for underground nuclear power plants.
背景技术 Background technique
国产65万千瓦堆型、M310堆型、AP1000堆型、ACP1000堆型等堆型的核电厂在总体布置上，都设有反应堆厂房和燃料厂房（或辅助厂房），且厂房相邻且间距很小，厂房外壁间距不到100mm。反应堆厂房和燃料厂房之间通过燃料传输通道连接，传输通道既是燃料转运的通道，也是反应堆安全壳的密封屏蔽。以M310堆型核电厂为例，反应堆厂房换料水池内壁和燃料厂房传输水池内壁距离约为4200mm，燃料传输通道连接两个水池，在换料期间，水池连通，燃料组件在水下进行传输。在反应堆厂房和燃料厂房通过焊接为整体的传输管道连接起来，传输管道壁厚10mm的圆形管道，内径488mm，长约5542mm，内部焊有托架以支承行走轨道。穿过反应堆安全壳时，传输管道一侧焊接在厂房圆形通孔上；在贯穿燃料厂房时，两端各有一个封闭腔，可以检测泄漏。在传输管道一端装有闸阀，另一侧装有盲板。在反应堆运行期间，关闭闸阀和盲板，可以隔离反应堆厂房和燃料厂房；在换料期间，打开闸阀和盲板，则可以将两侧水池连接起来，从而可以实施换料操作。 In terms of overall layout, the domestic 650,000-kilowatt reactor type, M310 reactor type, AP1000 reactor type, and ACP1000 reactor type nuclear power plants are equipped with reactor buildings and fuel buildings (or auxiliary buildings), and the buildings are adjacent and spaced apart. Small, the distance between the outer walls of the factory building is less than 100mm. The reactor building and the fuel building are connected by a fuel transmission channel, which is not only a channel for fuel transfer, but also a sealed shield for the reactor containment vessel. Taking the M310 reactor type nuclear power plant as an example, the distance between the inner wall of the refueling pool of the reactor building and the inner wall of the transfer pool of the fuel building is about 4200mm. The fuel transmission channel connects the two pools. During refueling, the pools are connected and the fuel assemblies are transferred underwater. The reactor building and the fuel building are connected by a welded transmission pipe. The transmission pipe is a circular pipe with a wall thickness of 10mm, an inner diameter of 488mm, and a length of about 5542mm. A bracket is welded inside to support the walking track. When passing through the reactor containment, one side of the transmission pipe is welded to the circular through hole of the building; when passing through the fuel building, there is a closed cavity at both ends, which can detect leakage. A gate valve is installed at one end of the transmission pipeline, and a blind plate is installed at the other side. During the operation of the reactor, closing the gate valve and the blind plate can isolate the reactor building and the fuel plant; during the refueling period, opening the gate valve and the blind plate can connect the pools on both sides, so that the refueling operation can be implemented.
但是，上述传输通道布置形式仅适用于反应堆厂房和燃料厂房或辅助厂房间距较小布置形式，对于地下核电站，反应堆厂房与燃料厂房则处在不同洞室，厂房间距长达几十米，整个传输通道均布置在地下，现有的传输管道并不能应用，而且存在安装困难、检修困难等问题。 However, the arrangement of the above-mentioned transmission channels is only suitable for the arrangement with a relatively small distance between the reactor building and the fuel building or the auxiliary building. The channels are all arranged underground, the existing transmission pipelines cannot be used, and there are problems such as difficult installation and maintenance.
