This work deals with the validation of a high-fidelity multiphysics system coupling Serpent 2 Monte Carlo neutron transport code SUBCHANFLOW, subchannel thermalhydraulics code, and TRANSURANUS, fuel-performance analysis code. The results for full-core pin-by-pin burnup calculation ninth operating cycle Temelín II VVER-1000 plant, which starts from fresh core, are presented assessed using experi...

This paper presents the results of the parameter estimation procedure for the primary circuit dynamics of a VVER-type nuclear power plant. The model structure is a low dimensional lumped nonlinear model published previously in Fazekas et al. [2007a]. The parameter estimation method uses the modular decomposition of the system model for obtaining physically meaningful initial parameter estimates...

An increasing interest on the development of highly accurate methodologies in reactor physics is nowadays observed, mainly stimulated by availability vast computational resources. As a result, an on-going wide range coupled calculation tools observed within diverse projects worldwide. Under this framework, McSAFE European Union project coordinated effort aimed to develop multiphysics based Mont...
