Design of the exhaust system in the confinement of the HTR-10

Experimental study on the effect of mechanical ventilation conditions and fire dynamics on the pressure evolution in an air-tight compartment

“…In air-tight residential buildings, a mechanical ventilation system is applied to compensate for unintended adverse consequences due to airtightness in daily life [15,16]. Also, for industrial buildings, like the nuclear power plant, dynamic confinement is acquired by mechanical ventilation to ensure the safety requirements [3,17]. The ventilation condition has been proven to have an impact on the pressure variation [3,5].…”

Influence of fire heat release rate (HRR) evolutions on fire-induced pressure variations in air-tight compartments

“…Moreover, in industrial applications, the fire-induced pressure is able to undermine the dynamic confinement of nuclear power plant buildings, which may result in the release of hazardous contaminations [6,14]. Therefore, it is important for both the fire community and building community to better understand such a fire-induced pressure phenomenon.…”

Investigation of fires in a mechanically ventilated compartment using the CFD code FireFOAM

“…Nuclear facilities are equipped with mechanical ventilation networks that create dynamic confinement and control any possible release of radioactive materials during a fire outbreak (Jiang et al, 2002). In 2016, the Nuclear Energy Agency recorded 448 fire events from its twelve member countries at a varying period of observations for each member country, with the oldest observation start time of 1981 (NEA, 2016).…”
