Introduction

Scott Gladney, an Electric Engineer at the Tennessee Valley Authority’s Sequoyah facility, attributes smoother operations and the reduction of single points-of-failure to installation of the DCS and feedwater controls. Mr. Gladney states that “We were able to eliminate over 40 single points-of-failure per unit using the DCS feedwater controls. It also simplified the startup of our second feedwater pump. When starting the second pump, speed balancing used to be an operator-intensive manual procedure. The I/A Series block features allow for the controls to completely balance the pumps in automatic. Our swap over from startup valve to main valve was greatly simplified. It used to be an operator manual swap that took about an hour to perform. It is now an automatic event that occurs on they fly with no specific interaction required. I have seen a valve transfer occur as they were tying a turbine online (and in single element) with no significant level perturbations in the steam generators.” Mr. Gladney also stated how the controls were improved to have one set of tuning parameters, and one set of inputs. “If you have narrow range level, steam flow, and feedwater flow, that’s all you need to run single element or three element at any power level.”

The following are brief descriptions of some of the control enhancements delivered for various feedwater control systems throughout the nuclear industry by the nuclear control system engineering team of Invensys Operations Management.
