A recently completed PhD project tested and proved the feasibility of drying AGR fuels that had been stored for long periods in a caustic environment. The project successfully developed a drying process and proved that end points can be identified.
During the project, drying of perforated fuels was simulated in the main using pin holes, but a method to produce characteristic stress corrosion cracks in AGR cladding was used and these samples were used in some drying tests. A joint report to the NDA highlights that perforated cladding may have water ingress into the fuel and should be investigated.
This project will build on the previous knowledge by:
The project will use a combination of experimental testing (making use of the existing drying rig developed and installed at Leeds) and modelling of flow through the perforated cladding to inform experimental procedure and assist in prediction of process performance. The model will be validated using results from the drying rig.
