HECTR1.5 (Hydrogen Event-Containment Transient Response) is a lumped-volume containment analysis program that is most useful for performing parametric studies. Its main purpose is to analyze nuclear reactor accidents involving the transport and combustion of hydrogen, but HECTR can also function as an experiment analysis tool and can solve a limited set of other containment problems. Six gases; steam, nitrogen, oxygen, hydrogen, carbon monoxide, and carbon dioxide are modified along with sumps containing liquid water. HECTR can model virtually all the containment systems of importance in ice condenser, large dry and Mark III containments. A postprocessor, ACHILES1.5, is included. It processes the time-dependent variable output (compartment pressures, flow junction velocities, surface temperatures, etc.) produced by HECTR. ACHILES can produce tables and graphs of these data.
