This report describes the implementation and experience with Programmable Logic Controllers (PLC) for nuclear safety applications. Two applications are described. The first is an Anticipated Transient Without Scram (ATWS) mitigation system provided as a Diverse Auxiliary Feedwater Actuation System (DAFAS). It was implemented at Arizona Public Service`s Palo Verde Nuclear Generating Station and has been in commercial operation since early 1992. The second system described is an Emergency Diesel Generator Bus Load Sequencer installed at Florida Power and Light`s Turkey Point Nuclear Power Plant. This system was installed as part of an upgrade to the emergency power system in 1988. The experience gained in the design, development, implementation and qualification of these systems will be beneficial to utilities that are considering the utilization of PLCs for their plant applications.
