Configurable Logic in Fuel Handling Control

Abstract

Control and protective systems operating in the older nuclear power stations are nearing the end of their reliable operating life. These systems are still subject to frequent logic changes. Testing the software logic changes is becoming a significant task with ever greater expense. The software based systems can be replaced with systems using configurable logic. These systems provide new, more reliable technology, offer the capability for complete logic simulation and test before installation. There is a base of operating experience with these devices and many potential applications where they can be used to advantage.
