Yusef Rashid


Senior Associate

Advanced Engineering Analysis

Nuclear Fuel

Dr. Rashid has over 45 years of experience in the engineering analysis of complex structures.  As a contributor to the technical literature in Structural and Computational Mechanics, Nuclear Fuel Technology, and Materials behavioral Modeling, his work is internationally recognized and spans a wide range of activities, which include: three-dimensional finite element modeling and computations, material and computational modeling of creep and plasticity, irradiated materials characterization, computational fracture mechanics, elevated-temperature constitutive modeling in concrete and metal viscoplasticity, analytical modeling of nuclear fuel behavior, large scale computations in nuclear structures, failure analysis of reactor containment structures under severe reactor accidents, development of source-term-based methodology for spent fuel shipping casks, identification and evaluation of damage mechanisms in spent fuel dry storage, and modeling and analysis of spent-fuel subjected to the regulatory hypothetical transportation accident.  He has authored over 200 papers and reports in these areas, including 100 papers in nuclear fuel and reactor technology as shown in the attached list.  Many of Dr. Rashid’s publications are extensively cited in the technical literature, and he is credited by his peers with pioneering concrete constitutive modeling as part of his work on pre-stressed concrete pressure vessels for gas-cooled reactor applications at GA in the sixties.

Dr. Rashid is known for his expertise in spent fuel cask drop evaluation and is the author of the EPRI Target Hardness Methodology, which demonstrates that the upper bound of cask deceleration load is a small fraction of regulatory-target loads.  The target hardness methodology has been used by many utilities for responding to regulatory concerns regarding potential cask drop accidents in fuel facilities.
