Abstract:
In this talk, I will discuss the modeling and control of a large Pressurized Heavy Water Reactor (PHWR). First, the flux equations of the two energy groups will be discussed. It will be shown how these two group equations are converted into ordinary differential equations by using the nodal techniques. By applying one and a half group theory, these equations will be converted into one-group power equations for all the nodes. Finally, a linear model of 70th order, 14 inputs, and 14 outputs will be obtained in state space. The design of the controller for this reactor model will be discussed, and its efficacy will be illustrated by nonlinear simulation.
