is a Technical Specialist (Seismologist) on the staff of the Defense Nuclear Facilities Safety Board. He is responsible for technical issues involving natural phenomena hazards, nuclear facility safety and design, and general oversight of defense nuclear facilities. He has 30 years of experience with the evaluation and characterization of natural phenomena hazards and the design of critical facilities to resist these hazards. He has full knowledge of a wide range of nuclear facility regulations, regulatory guides, standards, manuals, guides, and review plans associated with nuclear facility design and evaluation. From 1990 to 2006, Mr. Kimball was the group lead for engineering design in the DOE National Nuclear Security Administration. He supervised technical staff responsible for technical review of nuclear facility designs and safety analysis. He led the development of seismic site characterization at numerous DOE sites, including the definition of the design basis earthquake, and led preparation of DOE standards and guides to define requirements and procedures to complete assessment of natural phenomena hazards.

Mr. Kimball was the DOE sponsor for the program that led to the “Recommendations for Probabilistic Seismic Hazard Analysis: Guidance on Uncertainty and Use of Experts,” commonly referred to as the SSHAC guidelines. From 1987 to 1990, he was a geophysicist in the DOE Office of Radioactive Waste, responsible for establishing the baseline site characterization plan for the Yucca Mountain high-level waste repository site. Before that, from 1984 to 1987, he was a senior geophysicist with Roy F. Weston Inc., participating in the review and development of environmental assessments for nine candidate high-level waste sites, and comparing and ranking sites for site characterization. From 1980 to 1984, he was a geophysicist with the NRC, participating in the review of safety analysis reports and developing appropriate sections of those reports. Mr. Kimball holds a BS in atmospheric and oceanic sciences and an MS in geosciences (geophysics/seismology), both from the University of Michigan.

He has co-authored a number of technical papers on seismic analysis and design. He is currently the Technical Interface for Southern Nuclear for the seismic portion of the Vogtle ESP and COL. Mr. Moore holds a BS in civil engineering from University of Alabama and an MS in engineering from The University of Alabama at Birmingham. He is a licensed Professional Engineer.

Mark D. Petersen, PhD
, is currently the Chief of the U.S. National Seismic Hazard Mapping Project of the U.S. Geological Survey in Golden, Colo., and also serves as a National Coordinator for the USGS Earthquake Hazards Program. Dr. Petersen was lead in developing the 1996 California state hazard maps (California Geological Survey) and the 2008 National Seismic Hazard Maps (USGS). He is responsible for the USGS seismic hazard maps that are applied in many modern building codes, implemented in earthquake insurance rates, and considered for public policy decisions. Dr. Petersen has served on several scientific committees, including the Working Group on California Earthquake Probabilities (1999, 2002, 2008); the Working Group on Utah Earthquake Probabilities (2010); the Science Advisory Board for the California Earthquake Authority (2003–2005); the Utah Seismic Safety Commission (2002–2010); the Global Earthquake Model (GEM) Modeling Advisory Group (2009–2010); the Advisory Board for the Swiss Seismological Service (2009); PEER Next Generation Attenuation Relations groups (2003–2010); and the PPRP for the CEUS-SSC Project (2008–2010). In addition to the hazard analyses, he has conducted seismic hazard assessments for Europe (Turkey); central Asia; Southeast Asia (India, Thailand, Cambodia, Vietnam, Laos, Indonesia, Singapore, Malaysia); Central America and the Caribbean (Panama, Puerto Rico, Virgin Islands); and South America (all countries). Dr. Petersen has a BS and MS in geology from Brigham Young University, and an MPhil and PhD from Columbia University’s Lamont-Doherty Earth Observatory.
