Description

Seal

The present invention relates to a seal that can be used to contain and transport nuclear waste, and more particularly to a seal that can permanently and safely store nuclear waste to avoid radiation leakage.

With the operation of nuclear power plants, nuclear waste generated during the period needs to be disposed of. Appropriate nuclear waste is disposed of in a storage container and placed in the ultimate storage field to be permanently confined to a fixed range. Since the half-life of radioactive nuclear waste is extremely long, the container used for storage needs to have strong corrosion resistance so that cracks can be generated without breaking, so as to achieve long-term storage until the radioactive waste of nuclear waste disappears.

At present, most of the materials used for storage of nuclear waste storage containers are made of concrete, cement, etc. Some nuclear waste storage containers are made of metal materials such as stainless steel.
