Numerical Simulation of a Compartment Fire in a Nulcear Power Plant Containment Building
J E. Floyd
The current trend towards the increased use of risk assessment in the regulation of nuclear power plants will soon result in changes in analysis of fire protection systems and methods. Before fire protection can be regulated on a risk basis, a consensus must be reached on a number Issues. One key issue is what types of computational tools should be approved for analyzing fire events, and what types of scenarios those approved tools will be declared valid for.To aid in this discussion, three different methods of fire simulation are applied to the T52.14 oil pool fire test in the HDR containment test facility. These methods are a hand calculation, the zone model code CFAST, and the computational fluid dynamics code FDS. Each is applied to a steady-state portion of the T52.14 test using, to the extent possible, the same set of input parameters.The results of computation are compared to the T52.14 test data. The comparisons show that each method is potentially suitable for use depending on the information required from the simulation. Each method will potentially have a role to play in risk based regulation depending on the scenario.
