Domestic production of high specific activity ⁶⁰Co was halted after a target rupture in 2012 at the Advanced Test Reactor (ATR). The Isotope Program (IP) within the US Department of Energy (DOE) Office of Science tasked a multilaboratory team of researchers and managers from Oak Ridge and Idaho National Laboratories with the redesign the radioisotope capsule. The objective of this effort was to create a more robust and reliable design, compared to the pre-2012 target. The team successfully completed this task to produce the DOE-IP cobalt (Co) production capsule design. Furthermore, 66 capsules were successfully fabricated by Oak Ridge National Laboratory (ORNL) and delivered to Idaho National Laboratory (INL) for irradiation in the ATR between January 2014 and October 2016. This paper describes the efforts of the team to prepare and disposition the two initial DOE-IP Co production capsules that were processed in March 2020. These efforts include performing accurate production predictions, experimentally validating predictions with assay measurements, shipping with the Orano-furnished Battelle Energy Alliance Research Reactor shipping package, and disassembling capsules at the isotope vendor site.

国内高比活生产⁶⁰在2012年先进测试反应堆（ATR）的目标破裂后，Co停产。美国能源部（DOE）科学办公室的同位素计划（IP）委托了橡树岭和爱达荷州国家实验室的研究人员和管理人员组成的多实验室团队，对放射性同位素胶囊进行了重新设计。与2012年前的目标相比，此工作的目标是创建一个更可靠，更可靠的设计。该团队成功完成了此任务，以生产DOE-IP钴（Co）生产胶囊设计。此外，橡树岭国家实验室（ORNL）成功制造了66个胶囊，并于2014年1月至2016年10月之间将其送交爱达荷州国家实验室（INL）进行ATR照射。
