Description

Technical Field

[0001] The invention relates to the field of radioactive cargo package transportation, in particular to a transportation device for radioactive containers. Background Art

[0002] In the process of handling radioactive waste from nuclear power plants, radioactive waste is usually placed in packaging containers, including traditional 130-liter, 220-liter or 480-liter cylindrical metal drums. Larger metal square containers can be used as outer packaging containers for cylindrical metal drums. Parallelepiped containers CMT do not produce unusable middle gaps, while stacking drums in an orthogonal or regular tetrahedral structure will produce such gaps. Therefore, CMT is often used in the nuclear field for the storage and transportation of radioactive waste.

[0003] In radioactive waste repositories, drums are used in combination with CMT containers and other packages of various sizes. In addition, many different operations must be performed: placing drums in larger drums or other containers, placing containers in larger containers, opening and closing container lids, stacking packages together, filling gaps or finally sealing packages... All these operations require a bridge crane to support multiple tools and must be remotely operated from a remote control room.

[0004] Replacing complex mechanical equipment with multiple integrated tools is a labor-intensive, risky and time-consuming task. In addition, when replacing in a radioactive environment, each replacement exposes the operator to radiation for a long time. According to international safety requirements stipulated by the ALARA standard, operators are kept as far away from the waste package as possible.

[0005] In order to reduce the time and risk of personnel in handling tool replacement operations, reduce personnel exposure to radiation, and save labor costs, a handling device for radioactive containers is proposed herein. Summary of the invention
