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...
