Post-irradiation Examination Techniques for Research Reactor Fuels


Book Description

Post-irradiation examination (PIE) is an indispensable step in the selection of new or improved research reactor fuel, and in the characterization and understanding of its in-core behaviour. This publication provides an introduction to PIE techniques. It describes a typical PIE process from intercycle inspections in the reactor pool or channel, to hot cell PIE, which is subdivided into non-destructive and destructive testing techniques with their typical output, advantages and drawbacks, and their applicability to understanding fuel irradiation behaviour. Much of the work presented in this publication originated from the research and development of new low enriched uranium research reactor fuels. Intended readers include research reactor operators, regulators and their technical support organizations, fuel developers and manufacturers, laboratory staff, and policy makers.













Measurement of Internal Pressure Buildup in Full-sized Fuel Rods During Irradiation


Book Description

Full-sized mixed-oxide fuel rods were instrumented to monitor internal gas pressures and plenum gas temperature during irradiation in the Plutonium Recycle Test Reactor (PRTR) at Battelle-Northwest. The successful operation of the experiments under different operating conditions for over fifteen months in the reactor provided information related to the sorbed gas behavior and fission gas release fraction as affected by fuel temperature and burnup.
