Closed-Loop Models

Using the coefficients of reactivity we have the final equation for the system representation, the feedback equation

dk = <5fc0 + £ aiiXi — Tia) + «v bV + aBS (1.59)

were temperature, voiding and burn-up feedbacks are included.

This equation, together with the kinetics equations and the thermal model equations, forms the complete representation of the reactor. The inter­dependence of these equations can be seen from closed-loop model diagrams.
