Hasan Charkas

Description: Discussion on their recent report on Digital Twin Applications for Advanced Reactors

Biography: Dr. Hasan Charkas has more than 22 years of experience in research and engineering and is a Principal Project Manager in the Advanced Nuclear Technology group at the Electric Power Research Institute (EPRI). Dr. Charkas manages the engineering design, construction, and project execution and optimization research areas to help deploy new nuclear power plants around the world. He also leads EPRI's nuclear research on digital twins.

Prior to joining EPRI, Hasan was the engineering supervisor for vessel internals engineering qualifications for Framatome Inc. He directed and managed engineers responsible for qualifications and stress calculations of components for nuclear steam supply systems (NSSS).

Prior to joining Framatome, Hasan designed structural strengthening solutions for deficient and under-designed structures for Structural Group Inc. He used nonconventional techniques like carbon fiber reinforced plates together with conventional engineering techniques including external post tensioning to design repair solutions for structures.

Dr. Charkas delivered engineering seminars to teach structural engineers how to design external strengthening reinforcement using composite materials and taught undergraduate engineering courses.

Dr. Charkas is a professional engineer licensed in the Commonwealth of Virginia. Hasan holds a Ph.D. in structural engineering from Kansas State University.

Description: A call to action for the development of a consensus based nuclear Digital Twin Guide for Advanced Reactor Design, Accident Simulation and Fleet Operation.

As an integral part of this Guide, an ASME Plant Systems Design standard is being developed by the Plant Systems Design Standards Committee. This standard is a building block for the use of Digital Twin approach to the design of advanced reactor plants.

The concept of this standard is to integrate systems engineering, qualitative and quantitative risk evaluations, and probabilistic design methods as the basis for the design processes. The standard integrates the design concepts of defense in depth, regulatory requirements, safety significance, risk-informed and performance-based principles into a technology-neutral design process. The standard will provide guidance on the integration of these concepts into the design process and support the overall integration into Digital Twin applications.
