Technology is being developed to identify and characterize spent fuel elements to establish if it is potentially suitable for retrieval and reprocessing. A remotely operated vehicle (ROV) deployable electrical resistance tomography (ERT) tool has been developed to identify the location of buried solids within sludge. Electrical field distribution measurement will be used from the sludge surface of the ponds to generate a conductivity map which will highlight the occurrence of buried metallic solids. A purposely built tomography based sensor capable of achieving detection of buried metal up to a depth of 50 cm (under trial conditions) has been developed. The proposed set of probes, arranged as a horizontal array, is encased in polytetrafluoroethylene (PTFE) and has no moving parts or electronics so to suit the requirements of operating under water. Further work is now ongoing to develop the technique to optimize interpretation of the volume and depth of the buried FGMSP spent fuel.

Benefits

The ability to identify and characterize spent fuel elements in sludge to establish if it is potentially suitable for retrieval and reprocessing.

Limitations

This technology is being developed and is not commercially available yet.
