I am a Principal Member of the Technical Staff in the Severe Reactor Accident Modeling and Analysis Department at Sandia National Laboratories. I work with the codes MELCOR and MACCS.MELCOR is a fully integrated, engineering-level computer code that models the progression of severe accidents in light-water reactor nuclear power plants. MELCOR is being developed at Sandia National Laboratories for the U.S. Nuclear Regulatory Commission as a second-generation plant risk assessment tool and the successor to the Source Term Code package. A broad spectrum of severe accident phenomena in both boiling and pressurized water reactors is treated in MELCOR in a unified framework. These include thermal-hydraulic response in the reactor coolant system, reactor cavity, containment, and confinement buildings; core heatup, degradation, and relocation; core-concrete attack; hydrogen production, transport, and combustion; fission product release and transport behavior. MELCOR applications include estimation of severe accident source terms, and their sensitivities and uncertainties in a variety of applications. MELCOR is also used to analyze design basis accidents for advanced plant applications (ESBWR, EPR, APWR).The MELCOR Accident Consequence Code Systems (MACCS) was developed at Sandia National Laboratories for the NRC. Its primary use is in performing PRAs for commercial nuclear reactors to evaluate the impact of accidental atmospheric releases of radiological materials on humans and on the surrounding environment. MACCS2 has been widely distributed and used by the NRC and its subcontractors, private industry, and throughout the U.S. Department of Energy complex. It has also been distributed to Cooperative Severe Accident Research Program (CSARP) members and other international organizations.For more information on MELCOR or MACCS visit:https://melcor.sandia.gov/
