Description

The present disclosure relates to an anti-tipping device for a low-level radioactive waste container.

In order to prevent storage containers of low-level radioactive waste from toppling due to an earthquake, a common practice is to reduce the number or height of stacked containers to ensure that stacked containers will not topple due to an earthquake of expected magnitude. However, this approach will reduce the space utilization of the storage library and increase storage-related costs.

In addition, it is also a feasible approach to install facilities or structures in the storage to prevent stacked containers from tipping over. However, this method not only reduces the space utilization of the storage, but also increases the complexity of related operations and the cost of construction of the storage, which indirectly Increase the radiation exposure dose and operating costs of relevant workers.

Therefore, the conventional method cannot effectively meet the requirement of preventing low-level radioactive waste containers from tipping over when they are stacked and stored.

Furthermore, since the present disclosure can increase the equivalent support area of stacked low-level radioactive waste containers through connecting devices, the number or height of stacked low-level radioactive waste containers can be increased, which will significantly increase the storage space. Utilization rate and reduction of costs associated with storage of low-level radioactive waste containers.

In addition, the present disclosure does not require the installation of additional facilities or structures in the storage warehouse to prevent the stacked containers from falling over. In addition to improving the space utilization of the storage warehouse, the use of connecting devices to connect adjacent stacked containers can also reduce the complexity of related operations and the construction cost of the storage warehouse, and indirectly reduce the radiation exposure dose and operation cost of related operators.
