Electrical cable sheaths are the most abundant fire load in nuclear power plants and fire is the most frequent internal aggression (one fire outbreak per year and per nuclear unit in France). A fire is threatening by two means: the heat it releases that may drive a fire growth and the smoke it yields, composed of gases and aerosols, that may be toxic and corrosive and interact with components in the area. At advanced stages, confined fires become oxygen depleted and the combustion regime shifts towards under-ventilated and vitiated combustion with the production of unburnt species leading to a higher threat. To assess the potential hazard of a confined fire, it is then of high importance to quantify the heat release, the gases and the aerosols produced by electrical cable sheaths fires in oxygen depleted conditions. To do so, a bench scale apparatus known as the controlled-atmosphere cone calorimeter (CACC) has been developed. The apparatus has been primarily qualified with PMMA plaques. Representative materials of PVC based electrical cable sheath have been formulated and manufactured in the shape of plaque samples. These materials have been characterized in terms of fire parameters (heat release rate, mass loss rate), evolved gases and evolved aerosols under different oxygen concentrations in under-ventilated conditions thanks to the CACC/FTIR/ELPI coupling. Vitiation lowers the heat release rate and decreases the fuel mass loss rate while under-ventilation increases unburnt species and aerosols production

.Wood materials play a key role in sustainable construction to tackle climate change. However, in the event of fire, they can contribute to fire growth, challenging their use. To improve understanding of fire risk, experimental studies have been carried out to examine the behavior of Cross-Laminated Timber (CLT) and wood fiber (WF) at various scales, from test bench to intermediate scale. These studies considered variations in temperature and oxygen concentration. The research focused on the potential interaction between CLT and WF, particularly in a wall/insulation configuration. The results indicated that oxygen depletion had a significant impact on the fire behavior, gas, and aerosol emissions of CLT, WF and CLT/WF. In addition, wood fiber negatively influenced the ignition of CLT under certain conditions. On a larger scale, the fire behavior and gas production of the CLT/WF assembly are like those of WF, with no interactions observed between the two materials

In the field of fire safety, the ignition and combustion of polymeric materials are closely linked to the ambient conditions, particularly the oxygen concentration. In the initial stages, the fire displays characteristics similar to a well-ventilated situation, but as the fire develops and the combustible materials burn, the availability of oxygen decreases. The fire moves into a state of under-oxygenation characterised by complex and unstable behaviour of the gaseous phase. Oxygen depletion also affects heat and mass transfer within the material under study, affecting its thermal decomposition and combustion, as well as the kinetics and nature of the gaseous products. Experimental studies aimed at characterising the influence of the under-oxygenation on the reaction to fire of solid materials are still very limited in the literature, and numerical models are often not validated for such atmospheres. In this context, the present work aims to characterise the thermal decomposition and the combustion of polymeric materials in contaminated environments, focusing on poly(methyl)methacrylate (PMMA). A controlled atmosphere calorimeter cone (CACC) was instrumented to characterise the influence of oxygen concentration on thermal decomposition and combustion processes: mass loss, temperature fields, heat flux, gas composition. During the experimental study, oxygen concentrations ranging from 10% to 21% were studied, for 3 different heat flows. The experimental results highlight the significant influence of oxygen concentration and external heat flux on heat and mass transfer as well as on PMMA combustion. Mass loss, heat release rate and temperatures show linear progression with oxygen concentration up to a certain value where the behaviour becomes chaotic and unpredictable. A dimensionless parameter representing the oxygen concentration was introduced, allowing suitable correlations to be found for the various parameters studied

After the beginning of a fire in a closed room, the oxygen rate in the atmosphere decreases. This implies an incomplete combustion and unburnt gases production. These ones may accumulate in the room or in ventilation pipes, and, after mixing with fresh air, auto-ignite. This could trigger a thermal accident such as backdraft. This present work, conducted for AREVA, aims to analyse this hazard and provide some methods to predict and prevent it. First, a bibliographical research, was carried on to define a mixture’s auto-ignition parameters. This study was based on Frank-Kamenetskii’s model: after establishing the energetics balance between the heat produced by combustion, and the one consumed by conduction, an auto-ignition critical parameter, δC, was defined. It reunites the system’s geometry, temperature (or the room temperature) and composition.Then, the High Density Polythene degradation in a Controlled Atmosphere Cone Calorimeter was studied. The effect on the material’s degradation of under-ventilation and of the energy brought has been tested through the oxygen concentration in the atmosphere and the incident heat flux.During this work many different gas mixtures were analyzed. On the ground of δC formula, the final step was to set the volume, through the radius (characteristic size of the system), as an auto-ignition parameter. Making the concentration of each combustible varying between the LFL and UFL and imposing the temperature allowed to predict this hazard
