摘要

核能约占全球能源产量的10%,在对气候变化的担忧日益加剧的情况下,核能被定位为实现碳中和的有希望的解决方案。然而,放射性废物的有效管理可能在长达10万年的时间里仍然具有危险性,这是维护公众信任和保障环境安全所必须解决的重大挑战。这篇综述概述了核退役的基本阶段,包括战略规划、净化、拆除、修复、封装、放松管制和作为可持续环境实践关键组成部分的场地再利用。该审查还强调了有效的除污过程对减少废物产生的重要性。各种去污技术,包括机械、机电、化学和先进的方法,如激光和等离子体去污,评估了它们的有效性和局限性。此外,审查强调需要在去污过程中加强离子交换树脂和潜在放射性核素的回收和再循环,以尽量减少浪费并解决潜在放射性核素资源的枯竭问题。今后的研究应优先考虑发展除污和放射性废物管理的创新技术,促进可持续的退役和支持以对环境负责的方式正在进行的核能发展。

Nuclear Decommissioning and Sustainable Environment: Insights on Decontamination Processes

Nuclear Decommissioning and Sustainable Environment: Insights on Decontamination Processes

Nuclear energy accounts for ≈10% of global energy production, positioning it as a promising solution for achieving carbon neutrality amid escalating concerns over climate change. Nonetheless, the effective management of radioactive waste, which can remain hazardous for up to one hundred thousand years, presents considerable challenges that must be addressed to uphold public trust and safeguard environmental safety. This review outlines the fundamental stages of nuclear decommissioning including strategic planning, decontamination, dismantling, remediation, encapsulation, deregulation, and site reuse as a critical component of sustainable environmental practices. The review also highlights the significance of efficient decontamination processes in reducing waste generation. Various decontamination techniques, including mechanical, electromechanical, chemical, and advanced methods such as laser and plasma decontamination, are evaluated for their effectiveness and limitations. Moreover, the review emphasizes the need to enhance the recovery and recycling of ion exchange resin and potential radionuclides during decontamination processes to minimize waste and to address the depletion of potential radionuclide resources. Future research should prioritize the development of innovative techniques for decontamination and radioactive waste management, fostering sustainable decommissioning and supporting the ongoing development of nuclear energy in an environmentally responsible manner.
