摘要： Transuranic waste generated at Department of Energy operations have been packaged to a large extent in unvented fifty-five gallon steel drums and have been stored with the intention of future retrieval. There are safety concerns regarding these drums because of a potential presence of hydrogen and methane generated by radiolysis of hydrogenous wastes and/or of traces of combustible volatile organic compounds contained in original waste materials. Methods and apparatus are provided for penetrating the packed drums and drum liner lids and for sampling and analyzing headspace gases as well as for purging undesirable gas mixtures and installing high efficiency particulate air filter vents. The steps of the method are performed by automated apparatus which is configured to isolate the drums having contents being tested from the surrounding environment and for inserting vents with filters concurrently with performing the tests.

摘要翻译： 能源部门产生的超铀废物在很大程度上被包装在未经许可的五十五加仑钢桶中，并且已经存储，以便将来检索。 由于氢废物和/或原废物中含有的可燃挥发性有机化合物的痕量产生的氢气和甲烷的潜在存在，对这些鼓有安全性的担忧。 提供了方法和装置，用于穿透包装的鼓和鼓衬套，并用于取样和分析顶空气体，以及用于清除不需要的气体混合物并安装高效颗粒空气过滤器通风口。 该方法的步骤由自动化装置执行，其被配置为将具有被测试内容的鼓与周围环境隔离并且用于在执行测试的同时插入带有过滤器的通风口。
