There is a technical document in reactor operation which contains neutronic calculations to predict reactor situation in different power lever and effective power days. Operators use this document which usually called Album of Reactor Core Neutronic to operate the reactor based on that. This document can also predict the date of reactor end of cycle using diminishing of Boron concentration until reaching to zero in the core but in many cases this prediction is not exactly the same with actual date; that is, approaching to end of cycle during reactor operation based on Boric Acid consumption is occurred sooner or later in comparison with calculation.
I want to know the main reasons of this discrepancy.
