This paper updates the analytical rationale and the computed results from those presented in the initial paper delivered on this subject (see the first reference listed below). The operational scheme is the same in this paper as in the earlier paper. The ACS Ventilation and Relief Valve (VRV) in the depressurizing Lab Module is wide open due to the need to suppress a large fire in the Lab or to remove the contaminated Lab atmosphere. All crew-men have evacuated the Lab Module and all previously open hatches in the Lab Module have been closed.
