Sampling methods and non-destructive examination techniques for large radioactive waste packages
Progress is reported on work undertaken to evaluate quality checking methods for radioactive wastes. This involved seven tasks: (i) identifying and developing techniques which may be used for the extraction of material from waste packages by coring techniques; (ii) comparing the conclusions from the coring programme with those from similar CEC programmes; (iii) preparing test pieces and representative samples from the extracted cores for chemical and physical analyses; (iv) assessing the importance and relevance of changes to the sample arising from modifications engendered by the coring processes; (v) developing rapid, non-labour intensive methods for the dissolution of powdered samples of cemented intermediate level waste; (vi) investigating the use of beta/gamma correlations as an aid to determining the radionuclide inventory of cemented intermediate level waste; (vii) assessing the potential of real-time X-ray video imaging techniques for the determination of spatial distribution and partial identification of the contents of drummed low level waste.
