Components of VVER engineering factors for peaking factors: status and trends
20th Symposium of AER on VVER Reactor Physics and Reactor Safety (2010, Hanasaari, Espoo, Finland)
Engineering factors
Abstract
One of the topics for discussion at special working group ?Elaboration of the
methodology for calculating the core design engineering factors? is the problem of
engineering factor components. The list of components corresponds to the phenomena that are
taken into account with the engineering factor. It is supposed the better understanding of the
influenced phenomena is important stage for developing unified methodology.
This paper presents some brief overview of components of the engineering factor for
VVER core peaking factors as they are in the Kurchatov Institute methodology. The evolution
of some components to less conservative values is observed. Author makes some assumptions
as for the further progress in components assessment.
