Risk Methodology and Evaluation
Safety Analysis, Hazards, and Risk Evaluation Expertise
Nuclear Engineering Division personnel have considerable experience in the field of
deterministic and probabilistic safety analysis. In deterministic analyses, facilities
and systems are analyzed to show that operating conditions will remain within design
tolerances. In probabilistic studies, hazards and risk evaluation models are used to
show, either qualitatively or quantitatively, which elements are most likely to
contribute to failure of a system or facility, and to indicate corresponding design
improvements.
This field covers a wide range of disciplines, usually requiring expertise in a number of areas (heat transfer, structural mechanics, materials properties, etc.) as well as familiarity with formal hazards and risk evaluation methods. Because of their extensive experience in many engineering disciplines, NE Division personnel are highly qualified to conduct the type of in-depth hazards and risk evaluations that are necessary for modern facilities to compete in today's highly regulated environment.
Areas of Application and Evaluation Methods
The following methods have been combined into state-of-the-art computer code packages which can be integrated with systems and components reliability databases to form a powerful tool for both qualitative and quantitative safety analyses, and hazards and risk evaluations.
