Abstract
In 1975, as a result of a blockage of the coolant inlet flow, two fuel plates of a fuel element of the BR2 reactor of the Belgian Nuclear Research Centre (SCK•CEN) have partially molten. This incident was included in the 1985 periodic safety analysis of BR2 and included in the IAEA database (Incident Reporting System Research Reactors). The element, consisting of HEU fuel plates (90 % 235U enriched UAlx fuel dispersed in an Al matrix), had accumulated a burn up of 21% 235U before it was removed from the reactor. Recently, the damaged fuel plates were sent to the hot laboratory (LHMA) for detailed PIE. In view of the scarceness of such datasets, the results of the microstructural analysis can provide valuable input for the research reactors community.
