[美国核军工管理局网站2006年10月2日报道]美国Y-12国家安全中心已完成高浓铀的重新安置工作,因此可以减少需要采取最严格保安措施的设施的数量。对这些材料的重新安置标志着Y-12在安全方面的重大改进,是Y-12在执行美国能源部设计基础威胁(DBT)计划的组成部分。此举将有效加强安全并提高设施的运行效率。 [US Nuclear War Administration website reported on October 2, 2006] The United States Y-12 National Security Center has completed the relocation of HEU and therefore can reduce the number of facilities that require the most stringent security measures. The relocation of these materials marks a significant safety improvement for the Y-12 and is part of the Y-12’s implementation of the DOE Design Basis of Threats (DBT) program. This will effectively enhance safety and improve the operational efficiency of the facility.
