| Abstract Scope |
Repository of high-level radioactive waste is one of the key issues in a nuclear power industry. The method developed in Sweden and Finland implies multi barrier and deep geological repository concepts. Spent nuclear fuel is planned to be stored in copper canisters with iron insets. The canisters will be sealed, embedded in bentonite clay and placed in the granite bedrock at a depth of 500 m. Thus, the copper canisters will be used as one of the barriers that provides complete isolation of spent nuclear fuel from the environment for at least 100 000 years. Although, the canisters will be stored in anoxic conditions which favors copper stability, ionizing radiation is one of the parameters that influences the degradation of the copper outer shell. Hereby we investigate stability and a mechanism of gamma-radiation induced corrosion of the copper in de-aerated water. |
