Modifications for the development of the MAAP-DOE code: Volume 3, A mechanistic model for combustion in integrated accident analysis: Task 3. 4. 5
A model for flammability characteristics and combustion of hydrogen and carbon monoxide mixtures is presented for application to severe accident analysis if advanced light water reactors (ALWRs). The purpose of the model development is to reduce uncertainty in the evaluation of fission product source terms for ALWRs through reduction in the uncertainty in phenomenological calculations. This is achieved because the model has a minimum number of adjustable parameters, and these parameters have a small range of variation. Background data on flammability and combustion are reviewed so that pertinent application can be made to the model. The mathematical formulation of the model is described and a driver program is demonstrated to be validated. The model is applied to four sets of recent hydrogen combustion experiments involving premixed combustion, injection conditions, quiescent and turbulent atmospheres, and inertants. These model benchmarks validate the model for the recommended model parameter values.
