An improved projected predictor-corrector method for Gd-bearing fuel burnup calculations

The accuracy of the conventional predictor-corrector(PC) fuel depletion method breaks down for the Gd-bearing fuel when coarse timestep is adopted.To resolve this issue,the projected predictor-corrector(PPC) method which assumes the reaction rates are linear functions of the nuclide's atom density,was proposed by Yamamoto and significant accuracy gain was achieved for Gd-bearing fuel depletion calculation.This paper proposes an improved PPC method,which assumes a linear relation between the microscopic reaction rate and the natural logarithm of the nuclide's atom density for nuclides 155Gd and 157Gd.Verification calculations are performed against a 17×17 PWR Gd-bearing fuel assembly test problem,numerical results demonstrate that once the timestep is coarser than 25 days the new PPC method is better than the original PPC method.
