TheDENOPI project is part of this approach with the aim to gain knowledge in the SFP under loss of cooling or lossof coolant accident conditions and to better evaluate the safety margins. Questions are still pending regardingthe physical phenomena involved during the uncovery phase of the accident. Besides, the capabilities of a spraysystem to cool down a partially or totally uncovered assembly must be assessed. To address these issues, the ASPICfacility has been set up at the scale of one full height 17x17 rod bundle which is electrically heated. In this study,the results of a reference test are presented and discussed. For instance, the rod and wall section temperatures areanalyzed and a comparison is undertaken for the time evolution of these temperatures with and without the activation of the spray during the test. Besides, the impact of the spray on the outlet steam characteristics is examined. %G English %2 https://irsn.hal.science/irsn-04100245/document %2 https://irsn.hal.science/irsn-04100245/file/ICMF2023_Brillant_main.PDF %L irsn-04100245 %U https://irsn.hal.science/irsn-04100245 %~ IRSN %~ PSNRES %~ SEREX
