Outline
To address the challenges in the design of associated radioactive waste repository and ensure the long-term effectiveness of waste disposal, theoretical and experimental research were conducted on radionuclide migration control technologies for associated radioactive waste disposal sites. A three-dimensional pollution control technology system was established from three dimensions: source, process, and end. Through waste leaching experiments, stabilization agents were screened, and based on this, a new type of stabilization composite material was developed, which effectively resolved the acid rebound issue to a certain extent, achieving source control. Research on seepage process blockage constructed a three-dimensional waterproof intrusion system, blocking external water intrusion from multiple dimensions. For end-of-pipe pollution control technology, soil modification and retardation experiments were conducted using natural clay from a specific region, determining the optimal mixing ratio of modified materials and the thickness of the natural material anti-seepage layer.The practical applications were implemented for a provincial associated radioactive waste repository, and the results show the three-dimensional pollution prevention and control technology plays a critical role in controlling radionuclide migration.
