Abstract

The PBF scoping test was the first of a proposed series of in-reactor experiments to study the effects of a severe fuel damage accident under realistic conditions. Some of the results of this test have been published in open literature. Using this information an analysis of the heat transfer aspects of the test has been made using the computer code BUTRAN. In the analysis BUTRAN proved capable of reproducing the main features of the experiment. The modelling approximations did not result in any significant inaccuracies. There were however some discrepancies between the calculation and experiment. Possible origins of these are examined. One of the main differences is the prediction of larger clad - coolant temperature differences than in the experiment. Other codes appear to give similar results to BUTRAN so this topic needs to be examined in more detail.
