Verification, Validation and Uncertainty Quantification of Multi-Physics Modeling of Nuclear Reactors Woodhead Publishing Series in Energy Series

Langue : Anglais

Auteurs :

Verification, Validation and Uncertainty Quantification in Multi-Physics Modeling of Nuclear Reactors is a key reference for those tasked with ensuring the credibility and reliability of engineering models and simulations for the nuclear industry and nuclear energy research. The book has a strong focus on the verification and validation procedures required for the emerging multi-physics M&S tools that have great potential for use in the licensing of new reactors, as well as for power uprating and life extensions of operating reactors.

The first part of the book provides an introduction to nuclear reactors and their simulation challenges, as well as revising key definitions, concepts and terminology. Part II then focuses on verification, covering code verification, solution verification and the frontier discipline of multi-physics coupling verification. The following chapters address model validation and its applications to single and multi-scale models, and are followed by an extensive section on uncertainty quantification, again covering both theory and practice. The final part of the book considers in depth how to apply best estimate plus uncertainty (BEPU) methods in safety analyses and design of nuclear reactors.

This essential and authoritative guide will greatly assist engineers, scientists, regulators and students in applying rigorous verification, validation and uncertainty quantification methodologies to the M&S tools used in the nuclear industry.



  • Uniquely - and crucially for nuclear engineers - directly demonstrates the application of verification, validation and uncertainty methodologies to the modeling and simulation (M&S) of nuclear reactors
  • Equips the reader to develop a rigorously defensible validation process irrespective of the particular M&S tool used
  • Brings the audience up-to-speed in validation methods for traditional M&S tools, then extends the discussion to the emerging area of validation of multi-physics and multi-scale nuclear reactor simulations

Dr Avramova is a member of the US national validation canter (NEKVaC) and NEA/OECD Expert Group on Multi-Physics Validation (EGMPEBV), and the coordinator of the OECD/NEA LWR Uncertainty Analysis and Modelling (UAM) benchmark. In addition, she is coordinator and leader of three international NEA/OECD benchmark activities - the US NRC/OECD BFBT benchmark, NRC/OECD PSBT benchmark, and OECD/NEA benchmark on reactivity compensation with diluted boron by stepwise insertion of control rod cluster into the VVER-1000 core. She has more than 15 years’ expertise and experience in verification, validation and uncertainty quantification of multi-physics modeling of nuclear reactors and has published more than 40 peer-reviewed papers in this area in journals and proceedings of international conferences. She is one of the developers and instructors of a residential and distance education graduate level course entitled “Verification, Validation and Uncertainty Quantification in Multi-Physics Nuclear Reactor Analysis” at PSU and NCSU, which is also taught internationally as a one-week short course.
