ABSTRACT
STUDY ON REACTOR TRIP SYSTEMS PERFORMANCE OF EPR 1600. The study on reactor trip systems of European Pressurized Reactor (EPR) 1600 has been carried out. EPR design has applied several sophisticated safety feature in order to enhance the overall plant safety margin. One of the outstanding features was the implementation of fully digitalized instrumentation and control (I&C) system which could reduce human error sensitivity. I&C system of EPR 1600 was divided into four levels namely process interface, system automation, supervision and control unit, and business management systems. Plant protection system is part of automation systems. This system could actuate the reactor trip system automatically or manually by operator. Reactor trip system actuation process on EPR 1600 was carried out by Acquisition and Processing Unit and also the Actuation Logic Unit. The study showed that the advantages of EPR reactor trip system was lay on the reliability system which have four fold 100% redundancy, room separating between each division, the self supporting of each division to do the actuation system, and the implementation of 2/4 logic system.

Keywords: EPR 1600, instrumentation and control system, reactor trip system.
