Title

Light Water Reactor (LWR) core feedback and transient response

Prerequisites

None

Goal of the course

The course provides the basics of reactor kinetics and dynamics and training in LWR transient analysis with an emphasis to reactivity insertion and feedback modelling.

Content

This course teaches practical understanding of kinetics and feedback effects of reactor core transients by assessment of modeling approaches. In a first step delayed neutron theory and point reactor kinetics model will be reviewed followed by a comparative discussion of thermohydraulic feedback models and reactor dynamics. Next, the existing methods for spatial kinetics will be examined. This includes an introduction to different multi-physics and multi-scale coupling approaches for thermal-hydraulics and neutron kinetics. The course will discuss the internationally accepted verification and validation procedures and standard problems for coupled multi-dimensional dynamics codes. Cross-section parameterization methodologies for transient applications will be also reviewed. The course will involve computer exercises to illustrate the theoretical concepts and provide students with knowledge about state-of-the-art methods used to model reactor transients for safety evaluations. The computer exercises will include point kinetics model in COBRA-TF and the coupled multi-dimensional code NEM/COBRA-TF. The training part of the course will involve simulations of fast (rod ejection and rod drop) and slow (rod withdrawal) reactivity insertions in LWRs.

The course will be given in English.
