中国重视高浓铀安全，支持在技术和经济可行的情况下，最大限度减少高浓铀的使用。2015年9月，中国原子能科学研究院高浓铀研究堆卸出高浓铀堆芯；2016年3月，中国原子能科学研究院完成了高浓铀研究堆的低浓化改造工作。加纳高浓铀研究堆改造项目进展顺利。2014年9月，中国与加纳签署了《关于为研究堆协助供应低浓铀的协定》，项目正式进入实施阶段。2015年12月，中美签署相关商务合同，加纳研究堆低浓铀燃料元件开始加工。
China pays great attention to the safety and security of HEU and supports minimizing the use of HEU where technically and economically feasible. The core of the HEU research reactor in Chinese Institute of Atomic Energy was discharged in September 2015. The conversion of this reactor to using Low Enriched Uranium (LEU) was completed in March 2016 by Chinese Institute of Atomic Energy. The project of converting Ghana's HEU research reactor is steadily making progress. The project entered implementation stage after China and Ghana signed in September 2014 an agreement for assistance in securing LEU for a research reactor. With the signing of a commercial contract between China and the United States in December 2015, production of LEU fuel elements for Ghana's research reactor started.
中国愿本着自愿、务实的原则，与相关国家协商改造自中国进口的高浓铀研究堆，并与国际社会分享高浓铀研究堆低浓化改造技术经验。
China stands ready to consult with relevant countries on conversion of its China-origin HEU research reactors subject to voluntariness and feasibility, and is also willing to share with international community its experience and expertise in converting research reactors from using HEU to LEU.
五、强化放射源管理
5.Strengthening management of radioactive sources
中国支持在严格管理、确保安全的前提下，促进放射源在民用领域的应用，着力提升国内放射源安全水平。中国严格执行放射源安全管理标准，全方位涵盖放射源生产、销售、运输、使用、收贮等环节；全面推进中国各城市放射性废物库安保升级，完成《城市放射性废物库安全防范系统要求》，与美国开展放射源安保方面的合作；完成了1.5万多家放射源利用单位的安全检查，妥善处置了废旧放射源；加强放射源安全能力建设，积极开展人员培训和安保实战演练；推进放射源安保技术研发，开展高风险移动放射源跟踪系统、辐照装置安保技防措施等研究设计工作。
China supports promoting radioactive sources application in civil areas with the precondition of strict management and ensuring security, and works hard to enhance its domestic radioactive sources security. China strictly follows the security standards of radioactive sources management, which cover all related aspects including production, sales, transportation, use and storage of the radioactive sources. China has made comprehensive efforts to upgrade the security level of radioactive waste repositories in various cities in China, completed compilation of the document "Security Requirements for Radioactive Waste Repositories in Cities" and conducted cooperation with the United States on radioactive sources security. China conducted security inspections of over 15,000 users of radioactive sources and properly disposed of disused radioactive sources. China also works to promote capacity building of radioactive sources security, actively hosts training courses and field exercises, promotes research and development of radioactive sources security technologies, and is conducting research on a tracking system of high-risk mobile radioactive sources, as well as technical protection measures of radiation devices.
