【摘要】 国际原子能机构(IAEA)建立了比较完整的核保障体系并不断加以完善,以确保有能力核查保障协定所涉核材料所作申报的正确性和完整性。本文对IAEA核保障技术的建立和发展情况进行了描述。国内在核保障技术方面做了大量研究。建立和完善的针对不同对象的核材料非破坏性分析技术和破坏性分析技术在核材料管制中得到应用;在实体保护方面研发了封记技术,防伪胶粘封记与光纤电子封记已得到应用;建立了系列环境样品分析方法,其中微粒分析技术能力通过IAEA认证,微粉分析实验室正式纳入IAEA微粒分析网络实验室。对IAEA保障技术的发展趋势进行了分析,提出了核保障技术发展的建议。更多还原

【Abstract】 In order to assure the ability to verify the correctness and completeness of declared nuclear material related to safeguards agreement, International Atomic Energy Agency(IAEA) established a safeguards system and improved it continuously. The development of the safeguards technique by IAEA was described. The great effort on safeguards technique was made in China. The measurement of nuclear material including nondestructive analysis and destructive analysis was established. On line monitoring technique for uranium abundonce was applied at enrichment facilities. Sealing technology such as adhesive seal and optical-electric seal were used in nuclear material control. The methodologies for environment sampling analysis were developed. The particle analysis laboratory at China Institute of Atomic Energy(CIAE) passed through the certification by IAEA, and became the membership of IAEA Network of Analytical Laboratories. The trends of safeguards techniques by IAEA were followed. Advice on the development of safeguards techniques was suggested.更多还原
