Assay of PCM Crates and Drums using the BIL Solutions Ltd. Imaging DISPIM{sup R} System
- BIL Solutions Ltd., Hinton House, Risley, Warrington, WA3 6AT (United Kingdom)
BIL Solutions Ltd Decommissioning In-Situ Plutonium Inventory Monitor (DISPIM{sup R}) is a versatile neutron and gamma assay system designed to be deployable in a wide range of decommissioning and waste management situations. The system utilizes Totals and Coincidence neutron counting to determine both total Pu mass values and the 3D Pu mass distribution inside the target object. DISPIM{sup R}'s modular, mobile design allows the system to be used in the assay of a range of objects of varying size and shape in locations where alternative monitoring equipment would not normally be available. The DISPIM{sup R} system has recently been successfully used for the in-situ measurement of crated and drummed Plutonium Contaminated Material (PCM) waste items to provide Pu mass values in preparation for their treatment as part of a decommissioning program. A description of the operation of the DISPIM{sup R} system is given, including calibration of the system prior to the on-site survey, the measurement and quality control methodology employed during assay of waste items and discussion of the data analysis techniques. The results of 'imaging' measurements (i.e. Pu mass distribution results) recorded from the PCM crate measurements are likely to be of particular benefit when planning any future operations on these waste items. The results of this DISPIM{sup R} survey represent a complete solution for the customer with minimal requirement for use of their own resources. Technically substantiated Pu mass assay results have been provided which can now be easily adopted for use in criticality safety cases for the future treatment of these waste items. In summary, the DISPIM{sup R} system has successfully delivered a safe, fast and cost effective measurement solution to this challenging assay task and demonstrated its flexibility as a PCM monitoring system.
