Spent fuel container transportation plant and spent fuel container transportation method
The invention relates to a spent fuel container transportation workshop and a spent fuel container transportation method.The spent fuel container transportation workshop comprises a loading well, a preparation well and a hoisting opening which are sequentially arranged, the preparation well and the hoisting opening are communicated or separated through a gate, and a damping layer is arranged below the hoisting opening; the height difference between the bottom surface of the preparation well and the fuel operation hall is not larger than 9 m, and the height difference between the bottom surface of the preparation well and the container transport vehicle below the hoisting opening is not larger than 9 m; a water filling and draining pipeline is arranged in the preparation well, and a water pump and an isolating valve are arranged on the water filling and draining pipeline. By arranging a temporary water filling and draining system, arranging a gate to form stepped hoisting to reduce the hoisting height, arranging a damping layer and other measures, it is ensured that after a spent fuel container falling accident occurs, radioactive substances can be contained in a loading well and a preparation well, the integrity of the sealing boundary of the spent fuel container can be ensured in a hoisting opening, and the safety of the spent fuel container is ensured. And the risk that a large amount of radioactive substances are released to the environment after a spent fuel container falling accident occurs is reduced.
本发明涉及一种乏燃料容器运输厂房和乏燃料容器运输方法，包括依次设置的装载井、准备井和吊装口，所述准备井和吊装口之间通过闸门实现连通或隔断，所述吊装口下方设有减震层；准备井底面与燃料操作大厅的高度差不大于9m，所述准备井底面与所述吊装口下方的容器运输车辆的高度差不大于9m；所述准备井内设有充排水管线，所述充排水管线上设有水泵和隔离阀。本发明通过设置临时充排水系统、设置闸门形成台阶式吊运降低吊装高度、设置减震层等措施，确保乏燃料容器跌落事故发生后，在装载井和准备井中可保证放射性物质的包容，在吊装口中可保证乏燃料容器密封边界的完整性，降低乏燃料容器跌落事故发生后放射性物质向环境大量释放的风险。
