The Halden Reactor test series IFA-650 was part of the joint international programme of the Halden Reactor Project. These tests addressed the LOCA performance of high burnup fuel irradiated in commercial nuclear power plants.
IFA-650.10 (PWR fuel): moderate ballooning, fuel fragmentation and dispersal were indicated.
The fuel was supplied by EDF/FRAMATOME and had been irradiated in the French Graveline 5 PWR to 61 MWd/kgU. The target peak cladding temperature (PCT) was 850°C.
Rod burst was detected 249 s after the start of blow-down. Minor fuel relocation was confirmed by gamma scanning and PIE.
