| PRISME-2 | CSNI2042/01 | Report | 16-DEC-2020 |
Machines used:
The second phase (PRISME-2) was a follow-up of the first which provided valuable results to participants on room-to-room heat and smoke propagation, the effects of ventilation and the resulting thermal stresses to sensitive safety equipment in specific room configurations. As with phase one, phase two consisted of a series of fire and smoke propagation tests at the IRSN dedicated facility in Cadarache. Again, data from the project was used to study multi-room fires and for validation of fire computer codes.
The PRISME-2 project results addressed some outstanding safety issues particularly with respect to the appreciable uncertainties that exist in risk assessments for nuclear power plants due to gaps in knowledge and modelling capabilities on fire growth and propagation, on fire extinction phenomena, on the prediction of damage to equipment and on the treatment of plant and operator response to a fire event. Phase two also provided useful information on outstanding questions with respect to fire probabilistic safety assessments, in particular regarding how heat and smoke propagate from one room to another and the impact of smoke on safety-critical systems.
The technical program of phase two consisted of the following:
experiments related to smoke and hot gas propagation through a horizontal opening between two superimposed compartments,
fire spreading scenarios on real fire sources such as cable trays and electrical cabinets and fire propagation from one fire source to another,
fire extinction studies of the performance of various extinguishing systems,
an open test campaign to build-upon and further investigate some of the phenomena from the earlier campaigns.
The acronym PRISME comes from the French phrase “propagation d’un incendie pour des scénarios multi-locaux élémentaires”, which in English can be translated as "fire propagation in elementary, multi-room scenarios".
