Evaluation of history effects in full-core calculations
Original language description
Thanks to the rapid development of the computing power it is nowadays feasible to generate macroscopic data libraries for each computing node with its particular depletion history. The method is based on coupling the core physics code (ANDREA, which is aNEM-based 2-group diffusion code for VVER reactors) and the lattice code (HELIOS 2) in an iterative scheme. Each core physics code run establishes an estimate of the depletion history in terms of local parameter values (that is, values related to each of 7000 nodes of core discretization) depending on the local burnup; nodes with the same fuel composition and similar burnup history are grouped and then for each of the 700 "mutually different" nodes a new run of lattice code is performed, generating a new node-specific data library for the macrocode. The iterations are repeated until the power distribution has converged; however, usually only two iterations are needed due to the fact that also the node-specific libraries are parameteriz
