[en] This report describes the Dsf-P1 project Spray Cooling Heat Transfer Experiment in a BWR Bundle mock-up. It gives the philosophy behind the choice of test parameters which covered very extreme conservative assumptions for reactor application. The global influence of the test parameters on the rod cladding temperature is shown and comparisons between channel rewetting data and predictions are presented. When the test program was completed and the bundle dismantled, a severe bundle distortion was revealed. The originally planned evaluation of heat transfer coefficients was therefore limited to a very preliminary analysis. This report recommends a separate project with the purpose to perform a detailed mapping of the bundle distortion and to evaluate heat transfer coefficients. (author)
