In the nuclear industry, there is considerable interaction between fire and ventilation because the latter must keep on ensuring its function of radioactive substances confinement without contributing to the spread of fire. To take this interaction into account, the "Institut de Protection et de Sûreté Nucléaire" (IPSN) has been running a program of research for several years, combining the development of calculation codes and the performance of experiments. The present paper starts with an outline of the functionalities of the first version developed code based upon computer coupling of the FLAMME_S code (zones type fire code) with the SIMEVENT code (ventilation network code). It goes on to describe an example of comparison between the results supplied by the code and those obtained from experiment in a ventilated laboratory facility. Finally, it illustrates the potential of the tool so as to permit studies to be carried out into ventilation control best suited to reduce the impact of fire on ventilation network components.
