Relaxation of Quasi-Static Approach via Polynomial Interpolation in the Predictor Corrector Quasi-Static Method

摘要

In this paper, a relaxation of the predictor corrector Quasi-Static approach through polynomial interpolation of PK.E parameters has been introduced and tested with a one-dimensional two-group slab reactor without the presence of feedback effects. It is shown that for un-synchronized and large macro-step cases, the quadratic iPCQS method returns the most reliable estimation of power and reactivity evolution compared to conventional QS and PCQS methods.
