Risk and Reliability Modeling and Assessment Group

The Risk and Reliability Modeling and Assessment Group (RRMAG) conducts risk analyses of complex technological systems to provide quantitative information to decision-makers. The RRMAG has established expertise in integrated risk and reliability management, ranging from HAZOP techniques to detailed probabilistic risk assessments. While principally focused on domestic and foreign nuclear power plants, the group also examines risks in such diverse areas as aircraft performance, space shuttle components, chemical spills and electrical reliability. The RRMAG has performed reliability and risk analyses for the US NRC, DOE, FAA and others. Specific current applications include: risk-informing the regulations governing the operation of commercial nuclear power reactors; using risk insights to develop high-level, technology-neutral regulations for advanced reactor concepts; and establishing consensus standards for risk analyses to assure better quality, uniformity and consistency among practitioners.

One of ten national laboratories overseen and primarily funded by the Office of Science of the U.S. Department of Energy (DOE), Brookhaven National Laboratory conducts research in the physical, biomedical, and environmental sciences, as well as in energy technologies and national security. Brookhaven Lab also builds and operates major scientific facilities available to university, industry and government researchers. Brookhaven is operated and managed for DOE's Office of Science by Brookhaven Science Associates, a limited-liability company founded by Stony Brook University, the largest academic user of Laboratory facilities, and Battelle, a nonprofit, applied science and technology organization.
