NEW METHODS AND TECHNIQUES IN NUCLEAR SAFEGUARDS RESEARCH AND DEVELOPMENT

摘要

3. AEC-LADC-10034nThe implementation of an effective nuclear safeguards and materials management system requires direct physical methods of detecting, identifying and quantitatively analyzing fissionable materials in various practical configurations containing both fissionable and nonfissionable materials. To be most effective and useful, such assay methods should be nondestructive, rapid, accurate, and capable of being carried out under a wide range of both laboratory and field conditions;e. g. , in situ or on-line assay in materials processing plants, or in mobile isotonic assay stations for in-the-field use.
