Session 2A - Lectures by Fellows and Associates

Appa Rao Podile, University of Hyderabad, Hyderabad

Modelling and control of large size nuclear reactors

In this talk, the speaker will discuss the modelling and controlling of a large pressurized heavy water reactor (PHWR). At first, the flux equations of two energy groups will be discussed. It will be shown how these two group equations are converted into ordinary differential equations using the nodal techniques. By applying one and half group theory, these equations are converted into one group power equations for all the nodes. Finally, a linear model of 70th order, 14 inputs and 14 outputs are obtained in state space. The design of the controller will be discussed for this reactor model, and its efficacy will be illustrated by nonlinear simulation.
