Hydrogen combustion results from the Sandia intermediate-scale (VGES) tank and the Sandia critical-tube-diameter test facility. [PWR; BWR]

Sandia National Laboratories is currently involved in several experimental projects to provide data that will help quantify the threat of hydrogen combustion during LWR accidents. One project, which employs several experimental facilities, is the Variable Geometry Experimental System (VGES). The purpose of this paper is to present descriptions of an experimental results from two of these facilities: an intermediate-scale burn tank (approx. 5 m/sup 3/) and a critical-tube-diameter test facility.
