A vertical cable routing on different trays has been observed as worst case in case of fire. PVC (polyvinyl chloride) or FRNC (fire retardant non-corrosive) polymers have been used as cable insulation materials for cables typically being installed in German NPP. Each experiment has been repeated under pre-heated conditions. A propane gas burner has been used for igniting cables and an ethanol pool for pre-heating. Two different types of fire simulation codes (one 'lumped parameter' code - COCOSYS - and two three-dimensional computational fluid dynamics (CFD) codes - FDS and CFX) have been investigated with respect to their potential for predicting the experimental results. There were significant differences in the way of performing flame spread calculations in the codes. However, none of the models applied in the frame of this benchmark exercise was able to predict the cable flame spread in an adequate manner.
