摘要： A canister for storing radioactive materials includes a base plate, side wall and a top plate. The top plate includes a top surface with a top edge having a bevel, and with a channel set in from the top edge. The top plate is sealed to the sidewall by a weld formed between the beveled top edge and the top of the side wail. The base plate is sealed to a bottom of the sidewall, so that a sealed vessel is formed.

摘要： A system for storing radioactive materials includes a canister having a first hermetically sealed vessel having a first cavity, a second hermetically sealed vessel having a second cavity, the first vessel positioned in the second cavity, an interstitial space between the first and second vessels, and a test port through the second vessel in fluidic communication with the interstitial space. A conduit has a first end fluidically coupled to the test port, and a removable seal is operably coupled to a second end of the conduit.

摘要： A method for detecting gas leakage from a radioactive material sealed container includes measuring a temperature at a bottom portion of a metallic sealed container. A feeding air temperature of external air passing between the metallic sealed container and a concrete-made storage container is also measured. Presence of leakage of inactive gas is determined by comparing the temperatures or by utilizing a physical amount calculated by using the temperatures.
