Spectral-history modeling in DYN3D burnup calculations

Spectral-history modeling in DYN3D burnup calculations

Bilodid, Y.; Mittag, S.

Burnup spectral-history effects are reflected in deviations in the actual nuclide concentrations within the fuel. The deviations of different nuclides are correlated. It is possible to treat the nuclide concentration change by tracing only one nuclide – Pu-239. Implementation of historical correction for 2-group cross sections method in DYN3D is described in this paper.
