HDR reactor containment fire modeling with BRI2

John Rockett, Olavi Keski-Rahkonen, Liisa Heikkilä

Research output: Book/ReportReport


Fire tests at the German test reactor, HDR, were simulated using a Japanese zone model code, BRI2. Eight and ten room models of the containment building were developed. Critical phenomena occurring during simulation were explored. BRI2 can be used for this type of work but care must be exercised where a side wind increases entrainment by the fire plume. Horizontal vents were described by effective vertical vents. Effect of location of the vent to ambient was found critical during severely oxygen limited burning.
