Following the CABRI-REP Na program initiated in the early 90s, the CABRI-PWL program is now prepared in the frame of a broad international cooperation with the aim to provide data and knowledge for high burn-up advanced fuels submitted to a reactivity initiated accident under more representative reactor conditions. Twelve tests are foreseen, the two first being planned in 2002 in the CABRI sodium loop allowing obtainment of preliminary results on advanced fuels, the other ten being scheduled in the years 2005-2007 after renewal of the CABRI facility. These tests will be associated to clad mechanical characterization providing a complete data set for different fuel types tested in similar conditions. The CABRI PWL program will allow to establish data under more representative reactor conditions that will provide the industry and their respective regulatory agencies with the necessary knowledge for further fuel management evolutions.
