URS PROFESSIONAL SOLUTIONS LLC K. R. OKULA PROFESSIONAL EXPERIENCE:

URS Safety Management Solutions LLC 2000 to Present Advisory Engineer and Senior Fellow Advisor Dr. OKula is a lead technical consultant to the Department of Energys response plan to Defense Nuclear Facilities Safety Board (DNFSB) Recommendation 2010-1, Safety Analysis Requirements for Defining Adequate Protection for the Public and the Workers, in the area of completion of a DOE Accident Analysis Handbook. This project will complete an accident analysts desktop guide for performing consistent, standardized analysis to support Documented Safety Analysis for DOE facilities.

Kevin recently concluded activities as a member of the NRC-Sandia National Laboratories State-of-the-Art Reactor Consequence Analysis (SOARCA) Project Peer Review Committee. The SOARCA team provided recommendations on applying MACCS2 for modeling accident phenomena and subsequent off-site consequences from postulated severe reactor accidents. This activity supported the efforts of Sandia National Laboratories (SNL) and the Nuclear Regulatory Commission (NRC) to provide more realistic assessment of severe accidents.

Dr. OKula is also part of the Level 3 PRA Standard working group charged with developing an ANSI/ANS standard for Level 3 PRA analysis. He participated in a team that conducted an SQA gap analysis on the bioassay code [Integrated Modules for Bioassay Analysis (IMBA)] based on DOE G 414.1-4 requirements. He identified safety analysis codes that were designated as DOE toolbox codes, and oversaw production of the first documents (QA criteria and application plan, code guidance reports, and gap analysis) for six accident analysis codes designated for the DOE Safety Software Toolbox. He provided support to DOE/EH-31 (now DOE/HSS) for addressing SQA issues for safety analysis software. He was a contributor to DOE G 414.1-4, Safety Software Guide on SQA practices, procedures, and programs.

Kevin continues to support MACCS2 and related Severe Accident Mitigation Alternatives (SAMA) analysis issue resolution as a subject matter expert for a number of commercial nuclear plant license renewal applications. Included are the Pilgrim Nuclear Power Station, Indian Point Energy Center (Units 2 and 3), Davis-Besse Nuclear Plant, and Seabrook Nuclear Power Plants.

He was part of tritium environmental release analysis team that supported evaluation of tritium control and management areas for the Braidwood plant. He supported an initial SAMDA document for the Mitsubishi Heavy Industries (MHI) US-APWR (1610 MWe evolutionary PWR), as well as complete a control room habitability study for postulated toxic chemical gas releases.

Kevin was part of a Washington Group team that developed a Design Control Document (DCD) for the MHI US-APWR using input information from MHI. He was Chapter lead on Chapter 15 (Transient and Accident Analysis), and later transitioned to severe accident evaluation and documentation support to Chapter 19 (PRA and Severe Accidents). He was the Chapter 19 lead for PRA and Severe Accident for COLA development for the Pebble Bed Modular Reactor (PBMR).

Dr. OKula developed the outline, coordinated contributors, and assembled the first draft of the DOE Accident Analysis Guidebook, a reference guide for hazard, accident, and risk analysis of nuclear and chemical facilities operated in the DOE Complex. He is also the primary author and coordinator for the Accident Analysis Application Guide for the Oak Ridge contractor. Dr. OKula also developed a one-day course and exam for the guide, which he later presented to the Oak Ridge, Paducah, and Portsmouth staff.

Dr. OKula also led an independent V&V review for the DTRA of the U.K.-developed Urban Dispersion Model (UDM) software for predicting chemical and biological plume dispersion in city environments, and is leading projects to verify and validate chemical/biological simulation suite software applications for the Dugway Proving Ground (Utah), and the Edgewood Chemical Biological Center (ECBC) in Maryland.

URS PROFESSIONAL SOLUTIONS LLC K. R. OKULA Managing Member, Consequence Analysis 1997-2000 Dr. OKula was responsible for the consequence analysis associated with accident analysis sections of Documented Safety Analysis (DSA) reports and other safety basis documents for SRS, Oak Ridge, and other DOE nuclear facilities. He also developed the methodology and identified appropriate computer models for this purpose. Additionally, Dr. OKula developed training to enhance consistency and standardize analyses in the consequence analysis area. He was project manager for environmental assessment support to SRS on a transportation safety analysis using the RADTRAN code.

Dr. OKula coordinated development of a DOE Accident Analysis Guidebook involving over 10 sites and organizations. He also led the effort to produce Computer Model Recommendations for source term (fire, spill, and explosion), in-facility transport, and dispersion/consequence (radiological and chemical) areas.

Westinghouse Savannah River Company 1989 to 1997 Group Manager Dr. OKula managed consequence analyses associated with accident analysis sections of DSA reports and other safety basis documents. He also developed the associated methodologies and identified appropriate computer models. He was a member of the management team supporting Criticality Safety Evaluation preparation assisting Safe Sites of Colorado and the dispositioning of final criticality safety issues for the decommissioning and decontamination of nuclear facilities at the Rocky Flats Environmental Technology Site.

In a teaming arrangement with Science Applications International Corporation, Kevin initiated discussions that led to development of an emergency management enhancement tool to risk inform likely source terms. Applied this approach to a Savannah River nuclear facility (K Reactor), and was part of the team to provide this methodology for use on the British Advanced Gas-Cooled Reactors (AGRs) (for the United Kingdoms Nuclear Installation Inspectorate). Model was knowledge-based, and required development of an Accident Progression Event Tree (APET) for the facility in question.

Dr. OKula managed the completion of the SRS K Reactor PRA program. He was the lead for development of the K Reactor Source Term Predictor Model and assisted with the core technology lay-up program to preserve competencies in reactor safety. He coordinated a 25-person group responsible for K Reactor probabilistic and deterministic dose analyses, and led the examination of reduced power cases at project termination. He developed risk and dose management applications to cost-effectively prioritize facility modifications.

Kevin interfaced with DOE Independent and Senior Review teams to finalize study acceptance, and transitioned the risk assessment team to risk management functions for nuclear and waste processing facilities. In addition, he successfully prepared a 10 CFR 100 Siting white paper to resolve issues raised by the DNFSB, and teamed with DOE/HQ legal support to document resolutions. He led the development of a position paper demonstrating SRS Replacement Tritium Facility compliance with DOE Safety Policy (SEN-35-91).

Staff Engineer Dr. OKula led an analytical team quantifying the tritium source term during a Loss of River Water design basis accident. He evaluated airborne tritium levels with multi-cell CONTAIN model, interfaced with a multidisciplinary team to resolve Operational Readiness Review concerns, developed an SRS-specific methodology for applying MACCS as a tool for Level 3 PRA Applications, and applied CONTAIN code for K Reactor source term analysis.

PROFESSIONAL

SUMMARY

Dr. Hanna is a specialist in atmospheric turbulence and dispersion, in the analysis of meteorological and air quality data, and in the development, evaluation, and application of air quality models. He is an AMS Certified Consulting Meteorologist with over 40 years of experience. He has led several research and development projects involving, for example, the analysis of uncertainties of dispersion models, the statistical evaluations of hazardous gas dispersion models and regional ozone models, the development of models for the dispersion of emissions from tall power plant stacks, from offshore oil platforms, and from accidental and intentional releases of hazardous chemicals, and the analysis of data from large urban and regional field experiments. From 1988-1997, Dr. Hanna was Chief Editor of the Journal of Applied Meteorology, and has published over 150 articles in refereed journals, six chapters in books, and five books in which he is the primary author.

RELATED PROFESSIONAL EXPERIENCE Model Evaluation, Model Uncertainty, and Concentration Fluctuations Under support of the American Petroleum Institute, a statistical method for evaluating air quality models was developed and applied to many types of source scenarios, models, and field data sets. This method is now accepted as a standard in international research on dispersion model evaluation (e.g., see www.harmo.org/kit). The U.S. Air Force, the U.S. Army, and the American Petroleum Institute supported the further development of a framework for evaluating and for estimating the uncertainty in environmental models. During the past few years, the Department of Defense, the Department of Energy, the Environmental Protection Agency, and the Department of Homeland Security have sponsored additional studies of model evaluation methods, with emphasis on scenarios where chemical or biological agents might be released.

From 1993 through 2006, the Electric Power Research Institute supported the development of uncertainty analysis methods for photochemical grid models. The Nuclear Regulatory Commission has had Dr. Hanna review their uncertainty analysis methods for linked emissions-dispersion-exposure-risk consequence models. The American Petroleum Institute has had Dr.

Hanna lead a long-term study in which the uncertainties of dispersion models for toxic gases in urban areas were investigated. In November 2006, Dr. Hanna presented an invited talk on air quality model uncertainty at an EPA workshop on uncertainties in estimation of future changes in air quality due to changes in climate.

From 2004 through 2007, Dr. Hanna was a lead scientist in a Defense Threat Reduction Agency (DTRA) study involving improvements of methods to account for mesoscale and regional-scale uncertainties in transport and dispersion estimates.

From 2006 through 2010, Dr. Hanna led model evaluation efforts for the HPAC-Urban model and for Rockle-type urban models (supported by DTRA), for the JEM model (supported by DOD), and for the LATRA3D model (supported by the USAF).

Regional Air Quality Data Analysis and Model Evaluation

Dr. Hanna was the chief scientist for analysis of field data from several regional and urban-scale ozone experiments, including the South Central Coastal Cooperative Aerometric Monitoring Program (SCCCAMP), the Lake Michigan Ozone Study (LMOS), and the Gulf of Mexico Air Quality Study (GMAQS). He was the manager and chief scientist for the multi-agency Cross-Regional Model Evaluation project, in which four regional air quality models were evaluated with field data from the LMOS, Northeast, and SARMAP domains. From 1999 through 2005, Dr. Hanna was the chief scientist on two DOI/MMS-sponsored studies involving boundary layers and air quality in the Gulf of Mexico.

Dr. Hanna led a ten-year effort in which the effects of uncertainties in input parameters on the uncertainties in predictions of regional air quality models were assessed using Monte Carlo methods. In 2005, Dr. Hanna completed a study of the uncertainties in the BEIS3 model, which is used to estimate biogenic emissions for input to photochemical grid models. He led a Monte Carlo uncertainty study of model predictions of benzene and 1,3-butadiene in the Houston area.

Modeling of Turbulence and Diffusion Dr. Hanna has developed applied diffusion models for several industrial and governmental clients, including a diffusion model for complex terrain (RTDM) for the Westvaco Corporation, a model for overwater diffusion (OCD) for the Minerals Management Service, a cooling tower plume model (ATCOOL) for the Department of Energy (DOE), a model for diffusion from tall stacks (HPDM) for EPRI, a hazardous gas model for chemical reactions and thermodynamics associated with UF6 releases, and a baseline urban dispersion model.

In the past five years, Dr. Hannas baseline urban dispersion model was further enhanced for use in estimating impacts of possible terrorist attacks with chemical and biological agents. It was evaluated with field data from Los Angeles, Salt Lake City, Oklahoma City, and New York City.

He led the evaluation of DTRAs HPAC-Urban model with field data from Oklahoma City and New York City. He was the chief scientist of the Madison Square Garden-2005 (MSG05) tracer experiment in New York City.

Hazardous Gas Model Development and Analyses The American Institute of Chemical Engineers (AIChE) Center for Chemical Process Safety (CCPS) sponsored the writing of the Guidelines for use of Vapor Cloud Dispersion Models in 1987, and the preparation of greatly-enhanced second edition in 1996. The AIChE/CCPS also sponsored preparation of the 2002 book entitled Wind Flow and Vapor Cloud Dispersion at Industrial and Urban Sites.

A USAF/API study was completed in which 15 hazardous gas models were evaluated with data from 8 field studies.

An industry-government consortium supported the five-year PERF 93-16 Dispersion Modeling Project, including field and laboratory experiments, in which dense gas models were improved so that they account for high surface roughnesses, short-duration releases, and stable ambient conditions. Dr. Hanna was responsible for the planning and coordination of the technical components of the project and carried out the analysis of the Kit Fox field data and

the evaluation of the HGSYSTEM 3+ model.

From 2005 through the present, Dr. Hanna has led DARPA, DHS, DTRA, and Chlorine Chemistry Council studies of emissions and dispersion of chlorine released from railcars. In the DTRA study, source emission model improvements were made for Toxic Industrial Chemicals (TICs). He is currently analyzing the observations from the DHS Jack Rabbit chlorine and anhydrous ammonia field experiments, and is a member of the Scientific Advisory Board, responsible for planning future field experiments.

Hazardous Gas Modeling for DTRA, DOE-CBNP, and DHS From 1997-2002, Dr. Hanna was the director and chief scientist of the Coordinated Hazardous Atmospheric Release Modeling (CHARM) project at George Mason University. The research, supported by the Defense Threat Reduction Agency (DTRA), was concerned with development and evaluation of mesoscale meteorological models and atmospheric dispersion models for releases of chemical and biological agents. Also, from 2000 through the present, DHS is supporting studies focused on improvements in guidance given to emergency responders concerning transport and dispersion in urban areas.

Reviews of Diffusion Research Dr. Hanna has been requested to prepare written reviews of various aspects of diffusion research by many national and international agencies, industries, and universities. He is a member of peer-review panels for NRC, DOE, EPA, CDC, DHS, CARB, and DOD programs. In March, 1997, he chaired the Peer Review Panel for the Atmospheric Modeling Division of the EPA National Exposure Research Laboratory. In June, 2000, he was a member of the Peer Review Panel for the EPA research program on ozone and air toxics. In November, 1997, he chaired the Peer Review Panel for the U.S. modeling program for the Khamisiyah, Iraq, chemical releases. In 1998 he chaired the Peer Review Panel for the EPAs new AERMOD model. In 2000, he was member of the Peer Review Panel for the Army Research Offices Atmospheric Boundary Layer Program. In 2003, he was a reviewer of the DOE VTMX research program. In 2005, he was a reviewer of the DTRA Chemical/Biological Defense Science Program. In 2009, he gave a keynote address at the Workshop on Evaluations of IMAAC models (for DHS).

Teaching Experiences at Universities Dr. Hanna has been an adjunct professor and/or research professor at several universities during his career (Vanderbilt University from 1969 through 1973, University of Tennessee from 1974 through 1981, Harvard School of Public Health from 1983 through the present, and George Mason University from 1997 through 2002). Approximately once each year throughout this period, he has taught graduate-level courses in atmospheric turbulence and dispersion. The Vanderbilt and UT lectures were used as the basis for the textbook by Hanna, Briggs, and Hosker (1982), which has been widely adopted as a basic text at other universities. In addition, three or four times a year from 1987-1997, Dr. Hanna taught a two-day short course entitled Vapor Cloud Dispersion as part of AIChE/CCPS conferences. Since 2002, he has taught 8 to 16 lectures a year in Air Quality Meteorology graduate-level courses at HSPH in Boston and in their International Institute in Cyprus.

From 1997 through 2003, Dr. Hanna organized and ran the annual GMU July Workshop on Atmospheric Transport and Dispersion Modeling.

Business Experience In 1985, Dr Hanna was a cofounder of Sigma Research Corporation, which carried out basic and applied research on meteorology and air quality issues for a variety of clients. The company grew successfully and was purchased by Earth Tech in 1992. Since 1997, Dr. Hanna has continued his consulting under Hanna Consultants, and currently spends about three-fourths of his time on that effort. The other one-fourth of his time is spent at Harvard School of Public Health. Hanna Consultants projects are sponsored by government agencies, chemical industries, environmental consulting companies, industrial associations, and universities.

Expert Witness Dr. Hanna has provided testimony in depositions in several litigation cases and has testified in two trials and at two hearings. In most of these cases, he was required to apply and interpret atmospheric transport and dispersion models. He has modeled releases of methyl mercaptan, ammonia and chlorine from rail cars, oleum from valve ruptures, ammonia from a tank rupture, sulfuric acid from a stack, hydrogen sulfide from a missile spill, water vapor and particulates from paper mills and cooling towers, small particles and ozone from power plants over the eastern U.S., wind flows in Manhattan street canyons, and wind patterns and dispersion of potential releases from nuclear power plants.

On June 2, 2003, Dr. Hanna was one of seven scientists invited to testify at a hearing before the U.S. Congress Subcommittee on National Security, Emerging Threats, and International Relations, on the subject of Following Toxic Clouds: Science and Assumptions in Plume Modeling.
