The passive autocatalytic recombiner for flammable gas control in the light water reactor containment during postulated accident, has the unique feature which does not require any external driving force. However, the system performance has close interaction with thermal-hydraulic condition inside containment, and empirical correlations have been applied to date. Authors have developed mechanistic model which is applicable to extended atmospheric condition such as inerted containment. The new model has been incorporated into 3-dimensional CFD code, and verified against existing performance test data ranges from small to large scale. The analytical result shows good agreement with test data, and supports the model capability of recombiner performance prediction.
