NUCLEAR WASTE STORAGE CANISTERS AND METHOD OF FABRICATING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240013944 titled 'NUCLEAR WASTE STORAGE CANISTERS AND METHOD OF FABRICATING THE SAME

Simplified Explanation

The abstract describes a dry storage system for radioactive nuclear waste materials that utilizes a double-walled canister system. The canister system consists of a tubular inner shell that creates an internal cavity for storing the nuclear waste material. A first lid is sealably welded to one end of the inner shell, and a primary base plate with an annular closure flange is attached to the other end of the inner shell through an annular full thickness butt weld. The combination of the inner shell, first lid, and first end closure forms a sealed primary pressure retention barrier. Additionally, a tubular outer shell is connected to the inner shell through welding, creating a hermetically sealed secondary pressure retention barrier.

  • The patent describes a dry storage system for radioactive nuclear waste materials.
  • The system includes a double-walled canister with a tubular inner shell and an outer shell.
  • The inner shell has an internal cavity for storing the nuclear waste material.
  • A first lid is sealably welded to one end of the inner shell.
  • A primary base plate with an annular closure flange is attached to the other end of the inner shell through an annular full thickness butt weld.
  • The combination of the inner shell, first lid, and first end closure forms a sealed primary pressure retention barrier.
  • The outer shell is welded to the canister, creating a hermetically sealed secondary pressure retention barrier.

Potential Applications:

  • Storage and containment of radioactive nuclear waste materials.
  • Transportation of radioactive nuclear waste materials.

Problems Solved:

  • Provides a secure and sealed storage solution for radioactive nuclear waste materials.
  • Ensures the containment and retention of pressure within the canister system.

Benefits:

  • Enhanced safety and security for the storage and transportation of radioactive nuclear waste materials.
  • Minimizes the risk of leakage or release of radioactive materials.
  • Provides a robust and reliable storage system for long-term storage of nuclear waste.


Original Abstract Submitted

a dry storage systems for radioactive nuclear waste materials may include a double-walled canister system. the canister system may include a canister having a tubular inner shell defining an internal cavity for storing nuclear waste material, a first lid sealably welded to a first end of the inner shell, a primary base plate defining a peripheral edge portion and having an annular closure flange, and an annular full thickness butt weld formed at an abutment joint between the annular closure flange and a second end of the inner shell. the inner shell, first lid, and first end closure may collectively define a sealed primary pressure retention barrier. a tubular outer shell may adjoin the inner shell. the outer shell may be welded to the canister to form a hermetically sealed secondary pressure retention barrier.
