Full-scale experiments with different smokes

Full-scale fire experiments were carried out in a laboratory designed according to the standard EN54-9. The laboratory was instrumented with additional equipment such as thermocouples and flow meters, which are not used in standard fire sensitivity tests. This allows results to be used as experimental data for validation tasks of numerical fire simulation computerized fluid dynamics (CFD)-codes. The ultimate goal of the research is to model theoretically smoldering and flaming cable fires, their smoke production, transfer of smoke to detectors, as well as the response of detectors and fire alarm systems to potential fires. This would allow the use of numerical fire simulation to predict fire hazards in different fire scenarios found important in probability safety assessment (PSA) of nuclear power plants (NPPs). This report concentrates on explaining full-scale fire experiments in the smoke sensitivity laboratory and experimental results from fire experiments for validation tasks with CFD-codes or other numerical fire models.
