1 Subject Content and Application Scope This standard specifies the minimum characteristic requirements and inspection methods for bitumen solidified waste in low-and intermediate-level radioactive wastes (hereinafter referred to as bitumen solidified waste). This standard is applicable to the bitumen solidified waste disposed near surface; With regard to the bitumen solidified waste disposed in rock cavities, this standard may apply as a reference. 2 Normative References GB/T 267 Petroleum products-Determination of flash and fire points GB/T 4507 Test method for softening point of petroleum bitumens GB/T 7023 Long-term leach testing of solidified radioactive waste forms GB 9132 Regulations for shallow ground disposal of solid low and intermediate- level radioactive wastes GB 9133 Classification of radioactive waste GB 11806 Regulations for the Safe Transport of Radioactive Material GB 13600 Regulations for disposal of solid low and intermediate level radioactive wastes in rock cavities 3 Radioactive Specific Activity Limit of Bitumen Solidified Waste Radioactive specific activity of bitumen solidified waste must meet the relevant regulations and requirements of GB 9132 and GB 9133. 4 Performance Requirements Performance of bitumen solidified waste must meet the relevant regulations and requirements of GB 9132, GB 11806 and GB 13600. 4.1 Unevenness Unevenness of waste distributed in bitumen solidified waste shall not be greater than 2º. 4.2 Water ratio Water ratio of concentrated liquid waste bitumen solidified waste shall not be greater than 1% of weight of solidified waste.
