Abstract

Computational methods are commonly used in nuclear criticality safety evaluations to analyze systems and demonstrate that they are subcritical. With the increased usage of these computational methods, their validation has become increasingly important over the years. This seminar will provide some history on how the topic of validating neutron transport calculational methods in nuclear criticality safety has evolved. A detailed discussion of the important validation steps outlined in ANS ANSI 8.24 will be provided. Finally, the seminar will cover recent validation efforts to address issues related to nuclear criticality safety evaluations for LEU and high burnup nuclear fuel.

Biography

Walid A. Metwally obtained his B.Sc. and M.Sc. in Nuclear Engineering from Alexandria University, Egypt, in 1992 and 1997. In 1998 he joined the Department of Nuclear Engineering at North Carolina State University as a PhD. Student. He remained there until completing his doctorate. After completing his doctorate, he served as a Research Associate until 2003. Dr. Metwally also holds a Master of Science in Operations Research and a Masters degree in Business Administration. Walid worked at the Atomic Energy Authority in Egypt, NC State University, United Arab Emirates University, and Global Nuclear Fuel in Wilmington, NC. In 2012, Walid joined the University of Sharjah, UAE, where he founded and chaired the Nuclear Engineering and Mechanical Engineering Programs and also served as the vice dean of the College of Engineering. He currently is a Distinguished R&D Scientist and leads the Nuclear Criticality Safety Group in Oak Ridge National Laboratory. His expertise is concentrated in the fields of criticality analysis of nuclear fuel storage, radiation transport modeling, and radiation detection and measurement. Walid also serves as ABET commissioner and program evaluator, chair of the ANS Accreditation Policy and Procedures Committee, past chair of the UAE ANS local section, chair of Working Group 1 of the IAEA International Nuclear Security Education Network, and technical expert on IAEA missions and assignments.
