【Abstract】 The raw materials selection and the properties for nuclear waste concrete drum, the formula and properties of the concrete, the specification and technical quality requirement of the drum were described. The manufacture essentials and technology, the experiments and checks as well as the effective quality control and quality assurance carried out in the course of production were presented. The nuclear waste drum has a simple structure, easily available raw materials and rational formula for concrete. The compressive strength of the drum is more than 70 MPa, the tensile strength is more than 5 MPa, the permeability nitrogen is (2.16~3.6)x 10-18 m2. The error of the drum in dimensions is +2 mm. The external surface of the drum is smooth. The drum accords with China standards in the sandy surface, void and crack. The results shows China has the ability to develop and produce nuclear waste concrete container and lays the foundation for standardization and series of the nuclear waste container for packing and transporting in China.更多还原
