Fission gas release measurements in mixed carbide and mixed oxide fuel pins

Description

Fission Gas Release (FGR) and fuel swelling are two important facets of fuel performance. Release of fission gases results in degradation in heat transfer due to bond gas dilution and enhanced stress in the clad due to internal pressure, whereas, retention of fission gases in the fuel matrix causes swelling leading to the Fuel Clad Mechanical Interaction (FCMI). Hence estimation of FGR is important to evaluate the fuel performance. As a part of Post Irradiation Examination (PIE), FGR measurements has been carried out on Plutonium-rich mixed carbide fuel pins (U0.3Pu0.7)C of FBTR fuel sub-assembly (FSA) discharged at various burnup levels and on the fuel pins from a failed carbide sub-assembly. FGR measurements have also been carried out on the fuel pins of MOX test sub-assembly after a burn-up of 112 GWd/t. This paper discusses the results of gas release measurements in these fuel pins
