【摘要】 随着高温气冷堆由实验堆到示范堆的放大,相应地产生的核废物也将增加。核废物进入环境后会造成水、大气、土壤的污染,并通过各种途径进入人体引起损害。在环保和生态问题日益引起重视的今天,为了保障核电的可持续发展,必须解决好核废物处理处置的问题。"清洁生产"、"零排放"的要求都对工艺生产提出了更高的要求,只有满足上述要求才能实现可持续发展,因此,各种含放射性元素的废液处理成为重要的课题。本文利用当前现有的处理技术与方法,针对高温气冷堆球形燃料元件生产中陶瓷UO₂颗粒制备过程产生的工艺废液,概述了低放废液处理概念流程,实现了"零排放"的要求。更多还原

【Abstract】 Today,more and more people pay attention to the environmental protection and ecological environment.Along with the development of nuclear industry,many radioactive effluents may be discharged into environment,which can lead to the pollutions of water,atmosphere and soil.So radioactive effluents including low-activity and medium-level wastes solution treatments have been becoming one of significant subjects.High temperature gas-cooled reactor(HTR) is one of advanced nuclear reactors owing to its reliability,security and broad application in which the fabrication of spherical fuel element is a key technology.During the production of spherical fuel elements,the radioactive effluent treatment is necessary.Referring to the current treatment technologies and methods,the conceptual flowsheet of low-level radioactive effluent treatment during preparing spherical fuel elements was summarized which met the "Zero Emission" demand.更多还原
