High Burnup Fuel Cladding Materials R&D for Advanced Nuclear Systems

Modelling of Fission Gas Behaviour in High Burnup Nuclear Fuel

The safe and economic operation of nuclear power plants (NPPs) requires that the behaviour and performance of the fuel can be calculated reliably over its expected lifetime. This requires highly developed codes that treat the nuclear fuel in a general manner and which take into account the large number of in uences on fuel behaviour, e.g. thermal, mechanical, chemical, etc. Although many mature...

Recovery and Restructuring induced by Fission Energy Ions in High Burnup Nuclear Fuel

In light water commercial reactors, extensive change of grain structure was found at high burnup ceramic fuels. The mechanism is driven by bombardment of fission energy fragments and studies were conducted by combining accelerator based experiments and computer science. Specimen of CeO2 was used as simulation material of fuel ceramics. With swift heavy ion (Xe) irradiation on CeO2, with 210 MeV...
