The Lungmen Nuclear Power Station (LNPS) is currently under construction in Taiwan, which consists of two advanced boiling water reactor (ABWR) units. The instrumentation and control (I&C) systems of the LNPS are based on the state-of-the-art modernized fully integrated digital design. This paper presents regulatory overviews, regulatory requirements, current major regulatory issues, as well as the areas of regulatory concerns and the lessons learned on the digital I&C systems in the Lungmen Project.
