Thirty-two years experience in areas of chemical and process engineering, technical and safety analysis, operations and performance evaluation, and quality assurance. Acknowledged Subject Matter Expert on centrifugal contactors by the Department of Energy (Modular Caustic-Side Solvent Extraction Unit (MCU) at the Savannah River Site, Uranium Processing Facility at the Y-12 facility in Oak Ridge, TN). Designed Process to remove radioactive cesium from salt waste at the Savannah River Site utilizing centrifugal contactors. Took R&D concept through design, flowsheet development, contactor testing to deliver optimum performance, startup, and finally over five years of successful operation. Devised a flowsheet (new solvent) for the same process that would provide 2-3 orders of magnitude greater cesium removal. Optimimized centrifugal contactor performance for use with the new solvent. Process now in successful operation with orders of magnitude better performance. I have extensive theoretical knowledge of centrifugal operation and can predict setup parameters to optimize performance.

Have a strong working knowledge of nuclear design codes and safety basis/accident analysis which allows design of nuclear processes that meet applicable standards.

Expert may consult nationally and internationally, and is also local to the following cities: Augusta, Georgia - Athens, Georgia - Columbia, South Carolina - North Charleston, South Carolina - Greenville, South Carolina

Work History

Years Employer Title Department Responsibilities
Years: 2012 to 2014 Employer: General Atomics Title: Engineer IV Department: Fission Group Responsibilities: He is responsible for developing and testing the Caustic-Side Solvent Extraction process (to remove cesium) for the Salt Waste Processing Facility at the Savannah River Site. This includes development of processes for both the original solvent and the improved solvent. Also responsible for developing a cesium removal flowsheet for the DOE Hanford site.
Years: 2009 to 2012 Employer: Savannah River Remediation, LLC Title: Senior Engineer A Department: H-Tank Farm Engineering Responsibilities: He was the responsible Design Authority for the Modular Caustic-Side Solvent Extraction Unit (MCU) at the Savannah River Site. He developed the skills and technical theory to be recognized as a Subject Matter Expert on the design and operation of centrifugal contactors. He developed flowsheets for the process and tested the design using centrifugal contactors as small as 1" diameter to full-scale 5" and 10" diameter.
Years: 1998 to 2009 Employer: Westinghouse Savannah River Company Title: Senior Engineer Department: H-Tank Farm Engineering Responsibilities: He was an integral member of an interdisciplinary team to select a cesium removal technology to be developed to a full-scale process for use in the SRS H-Tank Farm Area. After down-selecting to four technologies, he designed a test program and performed testing of an ion-exchange process. Ultimately, a counter-current solvent extraction process (CSSX) was selected. He performed small scale testing with both simulant and radioactive salt waste. As the Design Authority, he designed a full-scale process and supervised construction and performed testing at the manufacturer and after installation at the site. The process has run successfully for over six years (design life of 3 years!).
Years: 1997 to 1998 Employer: Westinghouse Safety Management Solutions Title: Senior Engineer Department: Safety Analysis/Technical Safety Basis Responsibilities: He performed safety analysis calculations for processes at the Savannah River Site to support Safety Basis documentation required by the Department of Energy. He also developed Technical Specifications for the facilities adhere to assure compliance with the Safety Basis documentation.
Years: 1989 to 1997 Employer: Westinghouse Savannah River Company Title: Engineer A Department: Safety Analysis & Quality Assurance Responsibilities: He performed safety analysis calculations for potential accident scenarios at Savannah River Site nuclear reactors. He

Government Experience

Years Agency Role Description
Years: 1987 to 2014 Agency: Department of Energy Role: Contractor Description: He functioned in a variety of roles including, Design Design Authority, process design engineer, chemical separations,safety analysis, and quality assurance. Also served as Subject Matter Expert for NNSA.
