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.
