Application of the ARRAMIS Risk and Reliability Software to the Nuclear Accident Progression
The ARRAMIS risk and reliability analysis software suite developed by Sandia National Laboratories enables analysts to evaluate the safety and reliability of a wide range of complex systems whose failure results in high consequences. This software was originally designed to model the systems, responses, and phenomena associated with potential severe accidents at commercial nuclear power reactors by solving very large fault tree and event tree models. However, because of its power and versatility, ARRAMIS and its constituent analysis engines have recently been used to evaluate a wide variety of systems, including nuclear weapons, telecommunications facilities, robotic material handling systems, and aircraft systems using hybrid fault tree event tree analysis techniques incorporating fully integrated uncertainty analysis capabilities. This paper describes recent applications in the area of nuclear reactor accident progression analysis using a large event tree methodology and the ARRAMIS package.
