deinventory翻译？ 这个单词是由美国汉福德（hanford ：美国华盛顿州南部原子能研究重要中心）生产和处理的放射性金属钚过程中杜撰出来的单词。后来引申为清空, 清除的意思，通常是指把容器中有毒、易燃或放射性的物料清理出去，以及紧急情况下将这些有毒、易燃或放射性[wiki]化工[/wiki]物料清理出危险区域，进行妥善的储存。（the word ''de-inventory'' (usually written deinventory) was coined at the plutonium finishing plant on the hanford atomic reservation to describe this process. the cleanout of gloveboxes at the plutonium finishing plant illustrates typical deinventory operations. although tanks may have been previously drained of their solutions, residual contents remain for which the plutonium content must be estimated. normally, this is accomplished using non-destructive assay (nda) techniques that require conservative correction factors to compensate for tank wall shielding apparatus geometry, fissile material distribution, detector efficiencies, and detector locations. the plutonium inventory is usually overestimated. a kickoff meeting is held to review planned operations. then a criticality safety evaluation of the operations is written, and limits and controls are established. in practice, an evaluation may turn out to be significantly more difficult than it at first appeared, primarily due to uncertainties in the quantity and distribution of the residual plutonium and liquid. the evaluation process can sometimes be streamlined by taking advantage of similarities in design, plutonium inventory, and operations to a glovebox previously evaluated. if an existing criticality safety evaluation report (cser) can be shown to bound the new operations, it may be used as the basis for establishing limits and controls for the new operations. otherwise, a new cser must be completed and approved.）查看更多
