Method for synergistically fixing and sealing nuclear waste through 3D printing/grouting curing geopolymer
The invention belongs to the technical field of nuclear waste treatment, and discloses a method for synergistically fixing and sealing nuclear waste through 3D printing/grouting curing geopolymer. According to the method, the geopolymer is used for immobilizing and sealing the nuclear waste, and direct-writing type 3D printing and grouting curing are combined, so that regional segmentation and storage of nuclides in a micro-macro level are realized, a diffusion path is extended, a dynamic potential barrier is improved, and interface leaching of a nuclear immobilization system is blocked; the method is a key means for efficiently inhibiting nuclide diffusion, developing a nuclear waste solid sealing system which is stable in performance and conforms to the concept of green sustainable development, and provides a reference basis for further designing and optimizing solid waste and converting the solid waste into a green and low-cost nuclear waste solid sealing system.
本发明属于核废料处理技术领域，公开了一种3D打印/注浆固化地质聚合物协同固封核废料的方法。本发明使用地质聚合物来固封核废料，结合直写式3D打印和注浆固化，实现核素在微‑宏观层面的区域分割储置，延伸扩散路径，提升动力学势垒，阻断核固封体系界面浸出，是高效抑制核素扩散、开发性能稳定且符合绿色可持续发展理念的核废料固封体系的关键手段，为进一步设计和优化固废转化成绿色、低成本核废料固封体系提供参考依据。
