Abstract

Abstract

In order to solve the engineering problem of local radioactive hot spots caused by spent resin deposition in the process of radioactive spent resin long-distance pipeline transportation, a set of 1300 m spent resin ultra-long-distance pipeline system was constructed on the basis of theoretical calculation of pneumatic driven flow, comprehensive stress analysis of pipeline and engineering design combined with field practice. The pipeline adopts the design idea of overall smooth inner wall, pipeline self-compensation for the thermal expansion compensation, large bending radius square compensator and space Z-shaped compensation structure, etc. The valves and fittings are customized to match the inner diameter of the pipeline. After installation, the hydraulic test, simulated transportation test and engineering verification are carried out. The verification results show that the spent resin transportation pipeline has solved the engineering problem of local hot spots caused by spent resin deposition during long-distance pipeline transportation. The system has high inherent safety and simple operation, which significantly shortens the operation time, reduces the generation of secondary radioactive waste, reduces the labor intensity and radiation dose of personnel, and has good engineering application effect.
