The raw material selection and performance, concrete formulation and performance, barrel specifications and technical quality requirements of nuclear waste concrete bucket were reviewed. The manufacturing essentials, manufacturing process, experiment and testing as well as effective quality control and assurance of the whole process were expounded. The developed nuclear waste concrete bucket has a simple structure, convenient and easy-to-use raw materials and a reasonable formula of concrete. The technical indicators: the compressive strength is greater than 70MPa; tensile strength is greater than 5MPa; nitriding rate of (2.16 ~ 3.6) × 10 ~ (-18) m ~ 2 level;
