Estimating the term…
A treated waste has been treated so as to prevent diffusion of a substance to be disposed, of e.g., radionuclide “I”, that tends to occur when the waste is disposed of in reducing environment at an ultra-deep underground. The treated waste has a low-resolution compound containing “I”, e.g., “AgI”, and a high oxygen potential agent having a higher oxygen potential than the compound, e.g., “Fe2O3”. Ionization of the substance to be disposed, attributable to reduction of the compound, can be suppressed over a long time.
A treated waste treated so as to suppress release of a radioactive substance to be disposed when said waste is disposed of underground under reducing conditions, comprising:
A method for making a treated waste treated so as to suppress release of a radioactive substance to be disposed of underground under reducing conditions, said waste comprising a compound containing said radioactive substance to be disposed, and an inhibiting agent made of metal oxide for oxidizing a reducing agent so as to inhibit said reducing agent from reducing said compound that causes said radioactive substance to be released from said compound, said method comprising
