Understanding and predicting fuel performance at high burnup require improving our
understanding of transient fission gas release. High-burnup operations enable new …

Gaseous fission product generation, transport, and release can have a large impact on
nuclear fuel performance, degrading fuel and fuel–cladding gap properties. Over the past …

There has been a recent push to accelerate nuclear fuel qualification by combining
advanced modeling and simulation with accelerated separate effects irradiation testing. One …

In response to the nuclear industry desire to extend burnup beyond current licensing
practices, the US Nuclear Regulatory Commission (NRC) released a research information …

The modelling of fission gas behaviour is a crucial aspect of nuclear fuel performance
analysis in view of the related effects on the thermo-mechanical performance of the fuel rod …

ABSTRACT A desire to increase fuel burnup to decrease the cost of nuclear power plants
has led to significant interest within the nuclear industry to develop improved understanding …

A two-stage gas release model was examined to determine if it could provide a physically
realistic and accurate model for fission gas release under Prometheus conditions. The …

This report deals with a computational model for release of gaseous fission products from
mixed oxide (MOX) nuclear fuel with heterogeneous microstructure. The model treats fission …

A theoretical model has been used for predicting the behavior of fission gas and volatile
fission products (VFPs) in UO/sub 2/-base fuels during steady-state and transient conditions …

The behavior of fission gases (Xe, Kr) is of critical importance to nuclear fuel performance,
because it determines both the amount of fuel swelling and the quantity of fission gas …
