Improvement of computer codes used for fuel behaviour simulation (Fumex-III) : report of a coordinated research project 2008-2012

The modelling of the performance of nuclear fuel is crucial to the operation of nuclear power plants and comprises a key component of the demonstration of nuclear safety.

As the demands on fuel performance increase, fuel modelling codes need to develop and cover a wider range of operational and transient conditions.

This publication compares the predictions of current fuel modelling codes with data representing a wide range of fuel operational conditions.

The results demonstrate both excellent performance and areas for further development of the codes to support advanced fuel operations.
