Title: Regulatory Review of the Digital Plant Protection System for Advanced Power Reactor 1400

This paper presents the evaluation result and the regulatory approach of digital plant protection system (DPPS) for Advanced Power Reactor (APR-1400). Firstly, we discuss the issue associated with the integration of bistable processor (BP) and local coincidence logic processor (LCLP) as one of design changes over digital plant protection system. Secondly, regulatory approach is presented on the safety classification and the independence of the soft controller to be installed in digital engineered safety features actuation system (DESFAS). Finally, hardwired back up systems against common mode failure of a digital system and the safety classification of Remote Shutdown Panel (RSP) are described. (authors)
