DESCRIPTION:The Laboratory for Reactor Physics and System Behaviour (at EP
 FL and PSI\, Switzerland) has in recent years been developing a code syste
 m for reactor analysis based on the OpenFOAM numerical library. The main o
 bjective is to supplement available legacy codes with modern tools employi
 ng contemporary techniques in the fields of software engineering and compu
 tational analysis. In particular\, the research project aims to step beyon
 d currently available tools by providing high flexibility in terms of phys
 ical and geometrical complexity of the problems to solve\, high performanc
 es in terms of parallel computing\, and the possibility to easily tailor t
 he source code based on the needs of each user.\n\nThis presentation will 
 offer an overview of how OpenFOAM has been used to achieve these objective
 s. Some of the developed single-physics solvers will first be presented. A
 ttention will then be focused on the coupling of single-physics solvers in
 to an implicitly-coupled non-linear-consistent multi-physics solver for th
 e transient analysis of nuclear reactors. This solver couples together a m
 ulti-scale fine/coarse mesh sub-solver for thermal-hydraulics\, a multi-gr
 oup diffusion sub-solver for neutronics\, a displacement-based sub-solver 
 for thermal-mechanics and a finite-difference model for the temperature fi
 eld in the fuel. It is targeted towards the analysis of pin-based reactors
  (e.g.\, liquid metal fast reactors or light water reactors) or homogeneou
 s reactors (e.g.\, fast-spectrum molten salt reactors).
